Brand New First Quality Factory Direct
Sealed Maintenance Free
The valve regulated, spill-proof construction of this battery allows trouble-free, safe operation in any position. There is no need to add electrolyte, as gases generated during charging are recombined in a unique "oxygen cycle".
Long Service Life
A dependable service life can be expected under normal operating conditions.
Long Shelf Life
Low self-discharge rate allows for storage of fully charged batteries for longer periods of time before charging is required. Lower storage temperatures will further extend shelf life.
Wide Operating Temperature Range
May be discharged over a temperature range of -40°C to +60°C (-40°F to +140°F), and charged at temperatures ranging from -20°C to +50°C (4°F to +122°F).
The high-impact resistant battery case is made either of non-conductive ABS plastic or styrene. Large capacity batteries frequently have polypropylene cases, all of these materials impart great resistance to shock, vibration, chemicals and heat.

I installed these in my APC SMT3000RM. I'm in Seattle, and the power quality is very good. They ran for about 15 minutes and allowed my servers to shut down, but came in way under what my UPS initially estimated with a ~500W load. Assuming an 80% efficient inverter I would expect at least 30 minutes at this load (~5A per battery).
After two discharge cycles and about 10 months, my UPS started showing a red light, with an alarm, and email/sms alerts every 12 hours reminding me to replace the batteries. I contacted Battery Mart and they informed me that they were no longer under warranty (I had been traveling a lot for work and wasn't able to get the RMA until the 1 year had passed.) The runtime is now ~5 minutes and I have to live with this alarm until I purchase a new pack.
Sure, they do the job but I suspect these are sub-standard cells. I even hooked each one up to a NOCO G26000 to make sure they were properly charged, and then waiting another 24 hours to let them settle before assembling them into the 4x2 pack.
We bought these batteries for replacement in our battery backup system. They got the job done for a good price and we are completely satisfied.
I used these to rebuild my APC ups system. The wires were good so no need to purchase the whole unit when just the batteries needed replacing.
works great at half or less than half the cost of oem batteries.
