Brand New First Quality Factory Direct

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 is my second purchase of a battery pack for the same APC UPS. I have had it that long. The first battery pack was not
purchased from Battery Mart, and only lasted a little over 2 years. We will see how long this battery pack from Battery Mart
lasts. The battery pack consisting of 2 batteries fit the APC UPS just fine and it plugged right up. The "Replace Battery" light
went out and the UPS is working like a champ.

This battery is a direct replacement for the battery for my UPS. I could have bought it from the manufacturer of the UPS, but not only is it cheaper from Battery Mart, it's the identical battery from the same manufacturer.
