Tech Tip: Easy Front Mount Installations
This battery is supplied with unique terminal hardware (2 spacers and 2 bolts for cable to terminal connection). This hardware is required for proper installation on certain applications. Other hardware may damage terminals and should not be used. The spacers are required for front mount cable installation only! The top mount position does not require the round spacers, use supplied bolts only. Torque bolts to 6 to 8 ft. lbs. How A Front Mount Looks when Installed: |

.
Very happy with your battery fast shipping and great price works as advertised.
Been using big cranks for a few years in my powersports. They last!
I bought 2 of these ETX15 batteries, for our Yamaha 4-wheelers. I am a big fan of East Penn batteries, & there is an East Penn distributor near me -- he did not receive any of these batteries when East Penn made a batch of them, but Battery Mart DID receive some. So, I bought mine online, instead of buying locally. The Price was good, NO shipping & NO tax. The batteries were packaged extremely well -- about as Bullet-Proof as you will ever see, & they were boxed up separately. I definitely applaud Battery Mart for their packaging.
We have a lot of vehicles, ZTRs, riding mowers, tractors, etc -- I use East Penn's AGM batteries in everything that I can find them for. These ETX15 batteries fit the battery compartments very well, and they have "Dual Terminals" -- you can mount the cables on Top, or on the Side. The batteries came with good quality Bolts & special washers for the side mount. I am expecting to get 7-8 years of service out of these batteries -- BUT -- I do charge them up every month, year round. I am NOT getting paid for this review.
Excellent battery, arrived on time, charged and ready to go! Fantastic cranking power, much better than the junk from China. I would highly recommend this battery from this company.
