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.

as of yet I still do not have the new batteries installed into my electric tricycle...i purchased these same batteries a little over 2 yrs ago and must say i was disappointed that they only lasted almost 2 yrs! The original batteries that came installed in my trike lasted almost 4 yrs!!!! But i do appreciate that fact the battery mart has these batteries and for a good price, most places do not!

Strong Portable Power

I've tested these batteries separately and I can run an old CRT TV for 2 1/2 to 3 hours on a single charge with my portable power supply that uses an inverter. They will also power other tools as well with an for as long as I need them to finish my projects around the house, and It is convenient to have portable power to save time dragging power cords all over the place.

Saved $100 by ordering from Batterymart.com and replacing the 2 internal batteries myself vs buying a complete oem replacement. It was my 1st purchase from Batterymart and I couldn't be more satisfied.

Use this in a portable AC power pack and car battery jumpstarter. The other one died because I let it sit on the shelf for a couple of years. This model is supposed to replace the original battery, but the terminals are arranged a little differently, so I had to stretch those wires to connect to the new device. Not a huge deal, but there is some tension in the wires now. But it meets all the o
