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.

Great experience with Battery Mart. Website was informative and helpful in getting the right replacement for my Road King. Huge difference with the Big Crank over the OEM battery and great value.
Batterymart is the “go to” supplier for your battery needs!
The many Attributes; website is extremely user friendly, price and shipping (usually free) and the ever important “communication” aspect make this a very pleasant experience.
Once I ordered my battery the follow-up emails were very prompt and informative.
The battery I ordered for my bike for the second time within a ten year period is equal to or better than OEM. I use a battery tender which helps any battery, however, the batterymart battery lasted years longer than my stock Harley battery on the same tender.
As if it doesn't say "Harley-Davidson" a thousand times all over my Road King, I don't need their name on a battery they don't even make.
This is the USA made battery that HD sells (for $100 more) without their name on it.
Second one that I've purchased from Battery Mart in the past 10 years.
Best price, fast & free delivery, and made in the USA !!!
The 6 year old Big Crank ETX30L I'm using in my pontoon boat started acting wonky, so I ordered another. This is used to start a Mercury 60ELPTO, as well as power the navigation lights, fish finder/depth sounder, and stereo.
New one was strong as an ox after a top-off charge.
I put the old one on a smart charger, and now it tests out just fine. Probably could have kept using it after a good conditioning charge. Oh well, I'll keep it as a spare for my other projects.
Great battery. The one I replaced was 6 years old. Never had a problem with any batteries purchased. Would recommend.
Shipped quick. Packaged well. Fit perfect. Great company.
It was the right battery, great price, fit perfectly. Not much more you could ask for. Also shipping was fast, actually 2 days early.
