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).

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.

My large APC UPS just recently indicated the batteries needed service. The last time I replaced them, I had purchased these same brand/type batteries from BatteryMart back in 2002. They performed so well over the years that I purchased them again without hesitation.

Replaced batteries in large APC backup. New batteries were exactly same size and same connection configuration. Only took 15 minutes. New Batteries had 75% charge and were fully charged in under 1/2 hour.

I bought a set of these last year for my 2200XL UPS and they work great. Just bought a 2nd set for a Smart UPS 3000. They even came with new nuts and bolts. Just had to transfer the cables from the original batteries.
