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.

We've done business with Battery Mart going back over a decade, and for good reason. They always have the exact replacement battery we need for one of our many UPS units and they ship it out the door, quickly and efficiently. That's why we keep coming back.

Battery for Ryobi Mulchinator
September 3, 2013
by on September 3, 2013

There used to be a 24-volt battery, now they stick two 12-volt batteries together. What is essential for use in the Ryobi Mulchinator is that the size and shape match the tie-downs, and that the amp-hour rating be at least 18. This set went in just fine.
