    • Working fine in consumer UPS after 18 months
Style: 12.8V 9Ah
I have two of these doing very light duty as drop-in replacements in APC brand consumer UPS with small loads of under 100 watts each. I'm at about the 18 month mark and both of the batteries I have still pass the periodic UPS self-check and work fine during brief power blips of a couple seconds to about a minute. I haven't tested their extended runtime and tbh wouldn't necessarily trust them to give the full 9Ah worth of juice; my eventual plan is to set up the computers to start shutting down after an outage of more than 60 seconds. ... show more

    • Great price for power
Style: 12.8V 7Ah
Put in freezer overnight and the low temp works. Got two in parallel with charge controller and a 20 watt solar panel with a 500 watt inverter to charge my ryobi batteries. Works great

    • So light thought it was fake, and worked.
Style: 12.8V 9Ah
Worked right out of the box, I hope it lasts a long time. I hope all the lithium ion batteries overcharge mishaps don't happen too. My first time switching to this type battery for use in a theoretical longer lasting lifespan for my UPS or for those reading Backup battery supply for my electronics, pc, etc... Also way way lighter than a sealed lead acid battery of this size. At first I thought it was a scam and wouldn't worked never held one. Costs more than a lead acid but if it lasts years? Not saying it will but if it did, i have other Ups devices needing this treatment. ... show more

    • WARNING!
Style: 12.8V 9Ah
The reviews were great and I was excited to receive these batteries. I was convinced these were exactly what I needed for my deer feeders. I have always used lead acid batteries in my feeders and just pull them to recharge every few months when they drop in voltage too much. I don't have them hooked up to a recharging system of any kind. These worked great for about 2.5 months for one and 3 months for the other. In both cases, they had enough voltage to operate the timer and feeder normally and then died quickly to literally ZERO volts. The second one I ran a test throw on the timer, the feeder threw at full power, then the screen went blank. I pulled the battery and confirmed voltage was ZERO just like the first one. I spent about 2 weeks to try and get to take a charge and they will not. I then called Amazon and was told there was a 1 year warranty but I have passed the 30 day return deadline. No problem, they actually gave me contact emails to reach out to HWE. Their website contact info is 100% Chinese contacts and my attempts to contact them didn't work. So, I assumed that Amazon's contact emails would work but they just went into a black hole. No response at all after multiple attempts. My assumption is that if these batteries are recharged full time like in a UPS or something that maybe they are fine, but even UPS can fully drain a battery when power goes out. Be aware that these batteries have internal circuitry that literally kill it to ZERO volts if it gets drained too much and there is no bringing it back. Please note that there is no functional warranty either. I wouldn't purchase these again for any reason. ... show more

    • Note install date and keep track of how long it actually lasts!
Style: 12.8V 5Ah
So much lighter than a traditional 5AH lead acid battery that you question whether it will actually last as long as it should.
