Just wanted to check if I should take this to recycling or is there a fix for this? One of my two AGM batteries doesn't seem to take a charge, never reaches full charge, the Volt meter shows it at 4.0 to 4.4 wildly moving between numbers. Bought in 2019 but not use much. I bought twin batteries: htt...

I think you need both cables to go with the first battery, the 2nd one he mentions what he would need but doesn't show the actual cables for it. You need a cable that plugs into the battery, and the converter, the converter has a plug that fits that CPAP? If you cold find a converter with a plug for...

Above where he says the battery will be 5% higher or 12.6 V at 70% charge he says: 'Checking the terminal voltage of a lead acid battery – a fully charged 12 Volt battery can display an actual voltage up to 10% higher.' Or 13.2 at 100% so for whatever reason I am not getting that. Thanks for respond...

https://batteryguy.com/kb/knowledge-base/how-long-should-an-electric-wheelchairscooter-battery-last/#comment-44 If I understand this article, for the battery shown, drawing the battery down to 50% is as bad as 100%. While 50% gets twice the cycles, each cycle is half the power ? 70% is much much bet...

If anyone is interested, I used an old Radio Shack inverter to recharge a Scooter Battery after one night's use. I did not check how the charging was doing until I drove 6 hours. I used the same 3 amp charger I use at home so was thinking at least this would not blow a fuse. The next day I recharged...

I have something like this but from craftsman: https://www.amazon.com/gp/product/B004ZLY2MM/ref=as_li_tl?ie=UTF8&camp=1789&creative=9325&creativeASIN=B004ZLY2MM&linkCode=as2&tag=bestjumpstarterreviewcom-20&linkId=OECC7A3WKDBWEWZ2 I could post a picture if that helps. This trickle charges a dead car'...

Thanks No, I am not thinking of running the CPAP direct off the car battery with the car ON or OFF. I have several options while off the grid: I got the setup that you and camper van worked out on page (tab?) 12 of this thread for car camping. I have the transcend larger battery which gave me over 2...

Using an inverter? I was wondering what I could use and stumbled on this: https://www.subaruforester.org/threads/cigarette-lighter-after-ceramic-heater-fiasco.65840/ ' . . .And especially with inverters, do the math. They're usually specified in Watts of output. Double that for starters to account f...

CC their site says:

But what do I know? . . . about electricity.
