A GREAT "B.B. Battery HR9-12" replacement at a fraction of the cost
Trying to find replacement B.B. Battery HR9-12 which I cousin;t din at a reasonable price, I found these PowerMax 12V 9 Ah "replacements". I crossed my fingers, bought a pair, and replaced the batteries from a 10+ y/o GeekSquad (i.e. CyberPower-rebranded) 1500 UPS I had in storage and needed new Batteries. The UPS recognized these PowerStars as its original "B.B. Battery HR9-12" batteries and began working as it did the purchases at BestBuy 10+ years ago; supporting 2019 equipment. No Frankenstein here, the UPS with these PowerStars works and behaves as new.

Good high capacity batteries
The batteries arrived quickly well packaged and new as claimed. They fit my APC UPS fine and had a small initial charge. However my UPS has gone bad so I'll have to find another one to use these in. They did power it up fine but it refused to charge them and stays on battery power. Not the batteries fault. I will eventually repair or replace it and happily use these batteries.

Scooter Batteries
So far the batteries are working well, Razor E250 is ridden very little since installation. Charging was the problem with the original batteries. Have not tried to charge these. Installation a breeze.

Perfect replacement for the APC XS 1500.
These batteries seem like a perfect replacement for my APC XS 1500. Unlike most other batteries of the same type which are lighter, these batteries weigh about the same as the original batteries.
