Customer Reviews
Quick, just the battery I needed for my 2015 Prius
Good product
BATTERY MART PROVIDED THE MOST OUTSTANDING AND EFFICIENT SERVICE I HAVE ENCOUNTERED, BAR NONE!
THE DESCRIPTION OF THE PURCHASED PRODUCT WAS ACCURATE, WITH CLEAR SPECS AND REFERENCES TO THE TYPES OF VEHICLES IT WOULD FIT IN.
THE ORDER PROCESSING AND SHIPPING WAS LIGHTNING FAST!
GREAT JOB, BATTERY MART!!!
I WILL DEFINITELY RECOMMEND THIS ONLINE RETAILER!
This was the best priced battery I could find, easy to order, and had multiple shipment options to choose from. It was a perfect fit, too. Thank you for checking all the boxes, Battery Mart!
Great price for a Prius replacement battery. The battery has been performing flawlessly. I will look at Battery Mart for future batteries.
Got this battery for my Gen 2 Prius. Super fast shipping. It's exactly identical to the big brand battery that it replaced, made in the same place, probably the same factory. It works exactly as it should. Only difference is it's half the price!!
So, the price was my first reason for choosing this battery. But then I read the reviews and they implied that it was a Yuasa battery. Yes! So I trickle changed it, put it in a Prius that had been sitting for a year, and it started right up. It has been fine ever since, and Prius' are very sensitive to their 12v batteries.
