Small battery find

3 months ago

This battery was a great find. It is for a pull behind sprayer and thought it would be more difficult to source local. It is an exact for the one the sprayer came with and works great.

Helpful?

Brake Buddy

4 months ago

The battery fit into the break away trailer battery housing, the connectors fit perfectly. The battery came with a charge and worked perfectly straight from the box. I just installed a few days ago so I do not know how well the product will work for the long term but so far I am pleased.

Exact Replacement

Replaced factory battery exactly!

Check The Terminal Points

10 months ago

The battery terminals were too wide, even though the description said that these generic batteries would match. I had to go directly to the manufacturer, to get the correct model.

Good replacement battery

Great little battery, perfect fit in my small lawn tractor
