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.

Couldn't find an original match. Sooo as usual I went to BatteryMart and found a great replacement at 1/3 of the cost of.. Dropped In and works great.. Time will tell on the life.. Hopefully it'll last longer than the original..
I needed six new HC1221W batteries for my PurePower 2000 AC regenerator. I ordered on them on a Tuesday evening and the following Friday they arrived. Quick shipping, fresh batteries that were an exact match for what I needed, and a great price. I recommended Battery Mart to several friends, one of whom purchased six batteries for his PurePower 2000 from Battery Mart the following week. He is happy, too. I will shop Battery Mart again.
It can be hard to find the right batteries for large items like a UPS, you get the right rating but sometimes it doesn't fit.... but everything was perfect with Battery Mart :)
This battery was for my unit which controls my computers and printers if an electrical storm happens. Note When I opened the unit the battery had its description printed on it ---made it easier for me to order the right one for replacement..
Just what I needed - approrpriate for the device.
Bought 2 of these to replace worn/dead batteries in an APC back-ups. They fit perfect and worked great.
The battery came in very rapidly. I have used these batteries in the past to fix the "replace battery" light on my APC UPS units. However, this time the issue was not resolved. I checked the battery and it is a good battery and holds the charge. Therefore, the problem is with the UPS and has NOTHING TO DO with the product I purchased from Battery Mart.
