Honestly, when I am looking for a device to use during a power outage, a survival tool, I would want something with more features and can be used for more than one purpose. I have a jump starter that only jumps cars. Paid $25. In fact, that is what got me started using a jump starter for my cpap, using what I had on hand instead of buying a cpap battery. viewtopic.php?f=1&t=28154&p=242683&hilit=+jump+starter+25+reality#p242683
I thought it would be handy to have an inverter, an air compressor, a USB receptacle, and a charge indicator, so I bought one. Going on 2 years ago now. viewtopic.php?f=1&t=47625&p=434501&hilit=+jump+starter+25+1150#p434501
IF it died tomorrow, I'd prob buy another. IF it was just the battery, I'd fix it. Which is what attracted me to this Sears unit. Everyone knows Sears has good batteries and the manual said this battery is "User Replaceable".
Unfortunately, Sears no longer sells the exact placement battery because you can buy the battery elsewhere. So that's what I will do when the day comes that the steady charge kills the battery.
IF my buddy had given me the B&D BEFORE I bought the Sears 1150 I likely would have only replaced the battery in it and as a result only had the one battery during TS Irene in late Aug 2011. viewtopic.php?f=1&t=64943&p=615544&hilit=+jump+starter+25+black+decker#p615544
When reading a review that says it (a battery jump starter) worked fine but then 6 (8 or 10) months later it didn't work I just thought they didn't charge it at all during that time. Maybe not even before or AFTER the first use.
You can't just go out and buy a battery that has been sitting on the shelf (for who knows how long) and go camping this weekend or for a power outage that just happened and expect to get good results.
You have to plan these things and
1. charge the battery up to FULL capacity FIRST, maybe up to a week BEFORE use.
2. Buy or make a cable to fit whatever you will use it with.
3. AND try things out to make sure they do what you expect them to BEFORE you need them. Ever heard of "Fire Drills".
Also you should be aware that many, many websites have bogus reviews posted by bogus reviewers who also taint the competitions reviews. I know I don't rely solely on reviews for movies or restaurants either. What does not appeal to me may in fact appeal to you. As in this case.
IF I could find that $25 Roadmaster again, I would even pay $35 or $45 just for the battery. Then use the 17ah battery either in a UPS or the B&D jumper. You can't find the battery for that price even, so how do they do that?
