If you are using these batteries for a UPS please verify the quantity needed by looking in the owners manual, checking inside the UPS or calling us.

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).

Rugged Construction

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.

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..

Battery replacement for APC

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.
