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.

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.

Got this to replace the battery in one of our kids ride on electric wiggle car. Has been great since I installed it 3 months ago! The battery life is definitely better than the factory battery that came with it.

Direct fit to my garage door opener. Easy to install and great price. Seems like a quality battery and should last for a few years or longer.
