    • Nice battery for small applications
Set name: 12V 25Ah
I bought this to use with my RV pressure maintainer pump and it works great. We use it in an off grid rain barrel system to water our garden. I like that the battery indicates voltage and charge level easily with the push of a button. It is also light weight and fits nicely into my pump equipment box. ... show more

    • Working fine in consumer UPS after 18 months
Set name: 12V 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

    • So far so good.
Set name: 12V 20Ah
Battery works good and as it should. Having the screen is so convenient it's almost pointless to buy one without it. I have this one running a Garmin 10" chartplotter on my boat and it does amazing. Fits nicely anywhere I want on the boat. Light and small in size. You can't ask for much more at this price, it's a good buy but only time will tell how long it lasts. ... show more

    • UPS? It depends.
Set name: 12V 9Ah
It fit an common sized 1500VA home UPS and will restore it to working order. It will run and power appliance but do not expect anywhere near the original 1500VA rating if you replace its lead battery with this. Lead battery can output huge current, at least 62.5A for 2 in series powering full 1500VA load. They will only last like 2 minutes when brand new and will age very quickly if it happens frequently, but they can do it. LifePO4 cannot. They are usually rated at ~2C, which this one is close. It have a maximum discharge rating at 15A which is slightly less than 2C. This means your 1500VA UPS are now ~300VA. Any more it will trip battery over current protection and power will be gone. If you just want the UPS to power a common home PC, or maybe keep your router running during power loss, it will be great. UPS will be lighter and run for longer, with battery lasting longer than original lead(so less money per year), and the efficiency is way better for powering a under rated load. If you want it to actually carry anywhere close to 1500VA load lead battery is still the only way to go. ... show more

    • Excellent battery so far
Set name: 12V 20Ah
I have this connected in parallel with another 20AH battery. This has worked flawlessly on three 8 hour fishing trips so far with plenty of power left over. I may try running my live scope on this battery only just to test, but I don’t foresee any issues. Recommend for sure.

    • WARNING!
Set name: 12V 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

    • A good alternative

Your battery seems like a good option over the over priced OEM unit. It installed and changed just like it should. Only time will tell how long it will last, I have high hopes. The price sold me.
