This is the second time I have ordered a battery from Battery Mart, and I could not be more pleased. Just like the first one I ordered this second went right to work. It has functioned perfectly from the start. I will continue to use Battery Mart for all my battery needs!

I am partial to companies that do what they say they are going to do. Battery mart said that they had the battery I needed at a good price and that they would ship it to me promptly. They did all of those things. I would definitely do business with them again.

Met my expectations
June 2, 2020
by on June 2, 2020

My order was promptly processed and was in all respects accurate. The battery arrived a day earlier than I expected and has performed as I expected. It is intended to operate an electric golf cart that looks like a push or pull cart. It is important that it can operate over a long 18 hole golf course with steep hills and heavy grasses and the battery does that with a good bit of power left that would likely take it another 9 holes without a problem.

Almost a good day on the golf course

Ordered and received the battery that was perfect for my 20+ year old Kangaroo.
Charged it up ..... and due to our CURRENT CONFINEMENT .... Decided to take it for a short walk.
I live on the Harbour Town golf course ..... The course is currently closed to general play ...... I can easily play a four hole loop ... Off I went
Played One hole, then two, then three ...... and was coming down the last of the four holes when the local security truck pulled up beside me and said ....
ONE OF MY NEIGHBORS had complained about me being on the golf course ...... %$#?&*%$$@$&% ..... Nice security guard ..... He asked for my name, I told him Arnold Palmer
The end to an enjoyable hour ....THE BATTERY WORKED GREAT
