Review: Good battery for emergency and daily use - Excellent battery I use it with a converter and it has worked perfectly for cases of blackouts, charging cell phones. It's easy to connect, very useful practice. I totally recommend it.
Review: Well made batteries at a good price - Good batteries at a good price. One came DOA, and after I got a replacement for it, I finished cracking it open to see if it could be repaired in some way. (Do not do this unless you know exactly what you're doing as it is incredibly dangerous) While what the shipper did to it had unfortunately rendered it unsalvageable, I was surprised by just how well these are made. Ring terminals and screws rather than the poorly soldered connections common on 'budget' batteries, lots of foam padding that is properly glued on, and there was liberal use of some kind of rubber or silicone adhesive on anything that could come loose. I'm pretty sure it had to have fallen out of a moving truck for it to come DOA. As for the functional ones, I've cycled them a few times and even under a decent load they always pull at least rated capacity. But, that is to be expected considering that they're actually 314Ah cells under the hood. Whether that's what Dumfume intended, or if that's just what they got their hands on at the time, I don't know and I'm definitely not about to complain about it. The only issue I have with these is the odd size, and I knew that could be an issue going into it. The only battery box I've found that will fit these without being ludicrously large is a double GC2/Group 24 box, which is still a good bit too long for them. You'll have to do something custom if you want them fully enclosed. All in all though, I would not hesitate to buy more of these or another Dumfume battery. Like I said at the beginning, they are good batteries at a good price.
