ExpertPower 12V 7.2Ah Rechargeable Battery - Ideal for Emergency Backup Power

CashFlys: Based on the reviews I think some people luck out. However, my experience is two of these have failed within 3 months of use. I use them in a gate with a solar charger (regulated) so they get cycled and are under more short term load than a UPS. However, these have all failed in the same way - internal cell short (instantaneous capacity / voltage under load) loss. Not a gradual failure but instantly useless. To be clear, I have used BB and Yuasa (genuine) batteries for years in this gate. They all last multiple years (this is Texas and the sun/heat hits all batteries hard) getting an average of 3. These lasted 3 months. Will not purchase again. This is a very common problem on Amazon, junk batteries. If you use these in a "standby" device they may work ok if they are never under a moderate load (5+ amps) however I wouldn't depend on them. These are "toy grade."

csanback: Seems to hold a charge well. Installation into my Razor Quad was a little more difficult since I had to solder on the connections. But nothing that another battery could have done better.

Bob the Boomer: Shipping was pretty fast.
As far as quality goes, only time will tell.
I replaced a cluster of these in a Black & Decker cordless mower battery pack; OEM battery capacity was higher, about 8 AH, as I recall.
These 7.2 AH batteries weigh noticeably less in the refurbished battery pack; now, with having intentionally purchased less electrical capacity and less lead weight, the refurbished packs, sure enough, do not last as long in use as if I had bought higher capacity batteries.
My point/recommendation is for a consumer not to sell oneself short by buying lesser capacity, else you may notice that "you get what you pay for." This company has a wide range of batteries in this physical size that I could have purchased at a higher price.
Addendum 2/25/2018: I am really frustrated with my having chosen this lower amperage. These were ~ $18 each whereas I could have bought 9ah for $21 each. Today both of my battery packs ran out of juice well before the former original slightly higher amperage batteries would have. But it's not the fault of the battery. Phooey.

Jagman1: Purchased these for several different backup and power applications. All took their initial charge as expected and have now been in service for months without incident. True service life? Only time will tell if these are equal or superior to other brands I have utilized.

RickRick: I bought two of these to power my model 2 tennis tutor tennis ball machine. So far they are working Great! With batteries like these it's all about how long they will serve me. I will comment again if they don't last for very long...I am using a Battery Tender (022-0192) Black 12 Volt 0.750 Amp Junior Battery Charger/Maintainer to charge them after every use and have used them about 6 times for about an hour each time.

If these batteries last me for a while I'll come back and report.
