I purchased 2 batteries, one was clearly used and likely defective, covered in a fine orange powder. It had a different label than the other and even had a previous return label inside the box. Make sure you buy from a reputable source.

I have a Cyberpower SX950U UPS that, after a bit over three years of use, had a dead battery - the self test button was really just a shortcut to turn everything off. This battery is a perfect replacement for the 12V 7.2Ah SLA battery that was in there - if this battery was any larger it wouldn't be able to fit. It arrived with enough charge that the UPS treated it as completely full and it's running the UPS right now with the power cord completely disconnected. Certainly much more affordable than replacing the UPS as a whole.

I put this battery on my Vexilar for ice fishing. It is so much lighter than original, I love it!!! Wish I would have bought sooner.

Llevo probandola 3 meses, y he tenido excelentes resultados. La ocupe para sustituirla por bateria en NoBreak, y me ha dado muy buenos resultados. Al ser ciclo profundo y que tiene protector de (carga) balanceo, la bateria siempre esta cargada y funciona en el momento preciso. Si tienes un Nobreak y tu bateria se te agota de inmediato, con esta bateria no tendras problemas.

When I received these batteries a while back, one the batteries had no charge whatsoever. I could NOT even charge it. I had to apply a battery booster on it to give it basic charge so it will be recognized by the battery charger. Then, it took my 4.5 amp Battery Tender charger about 2 hours to completely charge it. So far, the two batteries seem to be working well for my Cyber Power backup unit. I tested the backup unit twice by unplugging the cord until the batteries are completely depleted. With minimal load of Modem, WiFi router, and an Ooma telephone unit, they lasted 200 minutes or little over 3 hours.

This battery served me well for a fairly long period of time; what's important is to obey their instructions and do not use more than 1/10 of the batterie's capacity for charging current.Do not overcharge -- set your device to disconnect at 13.8VIt is not designed to output the huge amount of current that the lead acid battery models can output while starting a generator for example.It may work fine if the generator is fairly small but not for the large and hard to turn models.But this is a fancy battery that should probably not be used to replace a generator's battery because even the charge cycle there is not the proper one for this model.There are a million other better ways to use this battery because it's light and it can hold the voltage under load much better than the lead acid does.It is wise to never discharge it all the way down to 12 volts. ( the charge level is measured without load)I am satisfied with this purchase.
