CPAP Battery Knockoff?

Post by Wildstar » Thu Aug 15, 2013 12:22 pm

Hi all,

Great forum! I purchased a Super CPAP Battery 266 watt hr from best cpap price dot com after doing research on this site. I use the resmed s9 and I know they have their own battery but it just didn't have a lot of reviews soooo...

I got the battery, among other things, with great shipping. However I noticed an oddity. The picture on the webpage is very different from what I got. One says :

http://www.bestcpapprice.com/Compact-Po ... p_516.html (mods feel free to delete url if this isn't ok.Image

is not what I got. What I got was this http://imgur.com/rn1w8oy

So to sum up their battery says "Super Cpap Battery Pack, Li Ion" and what I got says "Portable Power Supply". Smells fishy.

Second issue is that it is a full pound heavier than the description!

I am thinking I got a really poor, low quality Nickel Metal Hydride battery and not a Li-Ion.

I asked for a refund but they want to charge me 15% restock fee if you can believe that!

Did you use a credit card for the purchase? If so, contact your credit card company to see what, if anyhing, they can do.

Since the product delivered is not what they advertised, you should be able to just ship it back ( at your expense ) and get the credit card company to issue a credit for the full amount.

Just got this from Tom Malloy:

If the battery you send back is not absolutely exactly like it was shipped, and shows any signs of use by you whatsoever, it will be sent back to you. Any refund issued will be minus restocking fee and/or shipping charges as stated clearly in our return policy. As I emphasized before, we are not in the battery rental business. We are very responsive to our customers if the product actually has a problem or defect, but you are making accusations based solely on your own conjecture. I can provide you with ample proof that the batteries that we ship are in fact Lithium Ion Polymer, and not Nickel Metal Halide as you assume.

I will be interested to see what kind of response you get from the forum, because we have many satisfied customers there, and their parent site charges the same 15% restocking fee with a much less liberal return policy than we have.


Best Regards,

Tom Malloy


So hey Tom, since you are watching this thread...you say "absolutely exactly" So in other words the plastic wrap that no longer fits on the battery is not on it, and there are finger prints on it, are you saying to your customers that I need to wrap it in saran-wrap and wipe it down? I think what you mean by "absolutely exactly" is, "I am going to go over this with a fine tooth comb to make sure that I can stick it to you because I am mad." Just want to be clear before you make some other outrageous request.

Also its really insulting that you are lumping me into a group of consumers that would treat a serious purchase like this as a "battery rental business". Thats just slapping me across the face Tom.

My "conjecture" Tom is based on my expertise working in the cellular industry for 20 years and having a very good knowledge base between li-ion and nmh, which you should know supplier from China have no problem degrading their product to save a buck.

Take care of your customer Tom, people are watching.

Pretty clear from this response that you are not in to customer service but proving your point and making things worse. At this point I think this is good for people to know before they buy from your company.

It looks the same other than the label. Why do you think its not Li-ion? Did you weigh just the battery or all the gear?

Wildstar,

These batteries are manufactured in China by Owell Industries. They have a variety of labels on them.

I purchased one slightly over 2 years ago from Best CPAP Price. My unit is labeled "Super Portable Power Station" but is otherwise the same as pictured. The model number on the back of mine is OW-12-C266. The label also indicated the capacity is 266 WH (Watt Hours)

It will run my S9 Autoset for 2 nights using a 150 watt inverter. It will run my Intellipap Auto for at least 3 nights.

Check the label on your unit to see if your unit is what you ordered.

Bob

I weighed just the battery. I think its not li-ion because the specs said it weighed a pound less. li-ion is much much lighter than nmh.

How much does the one you got weigh? Another web site lists the weight at 9.1 pounds, battery only. I see bestcpapprice lists the weight at 5.0 pounds. Maybe yours is the Li-ion and not the Li-ion polymer, or the web sites just don't have good reliable data on them. What does the label have on it?

As mentioned above, the same product from a China factory can come over here with many different labels. If I were you I'd do a bunch of Internet searches on tool batteries and compare sizes, weights, and capacities to see if there is a real difference in size and weight for the same capacity and voltage.

On the other hand, China is notorious for sending fake products over here. You may have gotten stung, and then again you may not have. It's really hard to tell.

Hello,

I work for BestCPAPprice, and I want to take this opportunity to present our position on this issue and to affirm that the batteries that we sell are in fact Lithium Ion Polymer technology and not NMH as the original poster (for privacy reasons, I will refer to him as "Mr. S") is claiming. We have been selling these batteries since 2010, and have hundreds of them in the field. They have had a very good service rate or we would not be carrying them. In addition, we offer a full one-year warranty on our batteries, versus six months for some that are sold by others. Mr. S is referring to the fact that the case on his battery has the words "Portable Power Station" instead of "Super CPAP Battery Pack" like some of the earlier versions had on the case. I can assure everyone that these are the exact same batteries that we have been selling all along. The manufacturer has used several different iterations of wording on the case through the years, but this is the very first complaint we have had about what was written on the case not being the same as what is shown in the picture, or that the battery was heavier than the weight listed online. The fact remains that it is still a 12V LI Polymer battery with a reserve capacity rating of 266 w-hrs. We have had many very favorable reviews from CPAP users who were surprised at the long run times they were getting with their machines. Mr. S never complained about any performance issues with his battery, just that the wording on the case was different and that the battery he received was slightly heavier than what was listed.

Mr. S ordered this battery from us on July 11, and it was shipped the next day. On July 20 we received an email from the customer saying that we had sent him a "used / like new" battery. He wanted a second battery shipped immediately, with a UPS return shipping label. We promptly responded with the following email:

"I am sorry for your concerns.

I can assure you that all of the batteries that we sell are brand new. They come to us directly from the manufacturer overseas, five batteries to a carton, with no additional packaging aside from the travel case. We do take care to wrap them in bubble wrap and a sturdy carton to assure that they will arrive safely, but we do not package them in any type of fancy packaging. This allows us to pass on the cost savings to our customers. You will find that competitors are pricing similar batteries for $400 or more, and only giving a six-month warranty.

If you want to send us some photographs showing the areas that you are concerned with, we would be happy to evaluate them. Aside from that, we cannot send a second battery until we get the original one back from you. You can send it back to us through our product returns address, which I will provide below. If we find that you were somehow shipped a used battery, then we will refund your shipping and send another battery immediately.
"

We received no follow up from Mr. S until July 28, at which point he had changed his tune to say that we were selling a battery from a "copycat company". =>

"I'd like to return this. Something about it is not right. The specs for the battery say that it should weigh 2kg which is 4.4lbs. This unit weights 5.4lbs which makes me think that it is actually Nickel Metal Hydride and not Lithium or you are getting your batteries from a copycat company in China. In fact the unit doesn't say lithium anywhere.

Not happy."


We responded with the following:

"I can assure you that the batteries that we sell are Lithium Ion, and are not from a "copycat company in China". FYI, you will find that almost all of these batteries are constructed and assembled overseas. The specs that you are viewing were actually from the 222-w-hr batteries that we previously carried. Those had a lower LI content, so they weighed less. Thank you for bringing that to our attention - we will update the specs to reflect a more accurate weight.

These batteries typically hold a full charge for months at a time. Nickel Metal Hydride, while sometimes having similar reserve capacity to a LI cell, typically lose their charge much more rapidly while not in use.

If it has not been used, you can certainly send the battery back to us for a refund minus a 15% restocking fee per our Return Policy."


We were then answered by an email threatening to disparage our product on the online CPAP forums, and calling the restocking fee "exhorbitant",

"How about I go online to cpap forums and explain your justification of a exhorbitant %15 restock fee? You pictured a battery that says Super CPAP Battery and then Li-ion but mine shows no Li-ion on the battery. BTW Li-ion batteries weigh less than NMH.."

...to which we replied"

"Have you used the battery and found that it does not perform up to standards, or are you basing your assumptions purely on the fact that it does not say Lithium Ion on the case?

The photograph on the listing was taken when we first began offering the batteries from Owell. There have been several iterations of the verbiage on the battery cases over the years, with some saying "Super CPAP Battery", some saying "Super Portable Power Station", and others saying "Portable Power Supply". FWIW, we could pay extra to have whatever we want etched onto the battery case - even our logo could be placed there - but we would have to pass that cost on to our customers, and we do not think most customers are interested in paying extra for our advertising.

If you do a Google search on "CPAP" and "Return Policy", you will find that a 15% restocking fee is well within the norm. Some charge more than this. We have to account for the cost of shipping the item to you (since you got free shipping), evaluating it after it has been returned, and returning it to stock. Also, we have had incidents in the past where customers purchased batteries to use for a weekend trip, and then wanted to return them when they were done with them. We are not in the battery rental business. I apologize if this upsets you, but the return policy is clearly stated on our web site."


In reply, we received this little gem from Mr. S:

"You expect me to f____g believe that a manufacturing company is going to skip painting Li-Ion on a battery they are trying to sell?
This is not a lithium battery. The manufacture website says so. You're selling a knockoff.
And I didn't get free shipping, that's figured out in your overhead, you're not doing me any favors here.
Refund me 100 percent!"


I apologize to all of the users of this forum for boring you with the details of our back-and-forth emails, but I feel the necessity to defend our reputation, and since Mr. S decided to bring the emails into the thread, I thought I should give everyone the full picture. We absolutely stand behind every product that we sell, and we do our best to go the extra mile to assure our customers' full satisfaction, but we also cannot sell a product, allow it to be used, and then accept it back as a return after the fact and expect to stay in business very long. Restocking fees are a necessary part of doing business, and in almost all cases we try to work with our customers to avoid them if a product has not been removed from its packaging. This issue becomes even more critical with electronics, and you will see many vendors who will not accept returns on electronics at all.

We feel that we have tried our best to accommodate Mr. S, and we have clearly addressed the restocking fee in our Return Policy and displayed it prominently on our site. Mr. S stated that he thinks we are going over returned products with a "fine toothed comb" in order to "stick it to him", and he is partially right that we do have to carefully inspect any returned product to assure that it has not been used, but this is not so that we can "stick it to the customer". It is because we do not sell used products to our customers, and we have to take the time to make sure items that are going back on the shelf are not used. This inspection process takes time away from our employees that can be better spent helping our customers and shipping their orders. As stated previously, we usually suspend the restocking fee for customers who return products that are obviously unused and unopened, but this gentleman became confrontational and abusive in his emails to us, and we became suspicious that the battery had been used.

Thanks to the moderators of this forum for allowing us the opportunity to present our side of this issue. This is an excellent resource for CPAP users, and we appreciate it as well.

Well, this is certainly one online Cpap store that I will be AVOIDING.

Of course he sent you a "gem" of an email. Not everyone is able to keep their cool in the face of someone being unreasonable.


And obviously he did the right thing by bringing this public.

Remember to file with the BBB, FTC and your credit card company <IF> this company does not take care of you in a timely manner.

I have to say I'm strongly inclined to believe BestCPAPprice that the batteries actually are Li-ion. That said, if I had one, I'd probably be opening it up right now to see what the cells inside are. (But I really just look for excuses to open things up!)

I was not aware that LiPo batteries had been cleared for air travel, due to the risk of spontaneous explosion.
(just tossing that in there for the halibut)

Chunky, in regards to air travel with Lithium Ion batteries, travel within the USA with batteries this size is generally fine as a carry-on item. They absolutely do not allow LI batteries like these to be placed with checked baggage, due to the possibility of fire if they were damaged. International travel becomes a bit murkier, as we have noted documentation online that indicates that there is a 160 W-Hr limitation for some international flights. However, we have had several customers who reported taking their batteries with them overseas with no issues. I suppose the old saying "YMMV" applies here. We highly recommend checking with your carrier well in advance to see if restrictions are placed on LI batteries, and try to get something in writing. Regulations seem to be in a state of flux concerning what can be brought onto planes, so it is always best to do some homework.

I am referring to lithium polymer batteries, which have been documented to be less stable.

To the OP, what exactly is your primary concern here? Is the capacity of the battery less than the 22 AH advertised? For me, that would pretty much be my only real concern. If it's anywhere close to that capacity, there is no doubt that it's not NiMH as a such a battery would be quite a bit larger, and heavier. As to cheaper, price wise I would expect about the same. Myself, if I could get a NiMH with that sort of capacity in that size, it would probably be a better choice for me, and the way I would use the battery.

That said, for camping I use a group 24 wet cell lead acid to run my cpap in my Trailer. I prefer having it on it's on battery rather than tapping in to the house batteries, but I do have the trailer wired to use those as a backup.

I don't see any evidence of fraud here. Battery weighs more than posted... specs on the site are wrong, your scale isn't calibrated, you're weighing the battery AND enclosure.

If you're going to jump to conclusions about the battery chemistry of the one you got, why can't be it be nickel cadmium or LiFePo?

What it's labelled is not what's pictured. It's china. This happens all the time. Chances are the product is sold under a number of names, whoever ordered the most quantity got to decide what's silk screened... or they tried to make it seem like a 'bold new product!' or that's just how Chinese manufacture rolls.

Plenty of non-destructive methods you could use to determine the chemistry. Probably the simplest of which would be noting the charge behavior of the battery. NiMh and Lithium ion charge completely differently. You might also try looking at the full to depleted voltage curve. There may be externally visible divisions of cells (you'll have less cells with Lithium ion). You might study the differences in temperature performance and note if your pack coincides with NiMh behavior.

Dunno, seems like there's a lot of speculation and nothing that would even constitute a noteworthy anecdote.
