Best battery on the market.

BEST OUT THERE

these are the best batteries! my alternator went out in sacremento, calif. I still rode my fxr to bonneville! great battery, starts my 98" stroker and my 120" big bore drag motor! I have even tried the lithium-ion 540cca batteries, and big boar is a better battery!

i ordered this battery after my Yuasa failed 4 days prior my bike being shipped to Florida for a vacation. when it arrived i put it on a charger. it wouldn't take a charge. TOTALLY dead. i called J&P and listened to their exuses why they couldn't expedite shipping a replacement battery, even though their Anamosa facility is one day UPS from me. JUNK !

best cranking Battery I have found for my 93 inch shovel

5 by

its a new battery and works great

2 by

terminals can't handle vibration from 80" shovel, start's good

5 by

I am very pleased with my Big Boar battery. My 1986 heritage has never started so good. Love it...one happy camper here..thanks J&P.

5 by

Very good battery. Works as advertised.

4 by

Great battery, except for the fact that I had to install longer battery cables for my 09 FLHX. The terminals are on the side and opposite than the stock Harley battery.

5 by

Great battery. Be prepared to switch your positive and negative connections.

4 by

Switching the cables over to reverse the positive and negative sides is not as easy as the manufacturer states. Battery has plenty of CCA.

5 by

the best!

5 by

Easy install, gobs of power, what more can you ask for. BIG BOAR was the perfect solution for my bike. Can't believe how well it starts now.

5 by

Best battery for your HD on the market! This is my second Big Boar battery. I travel extensively and having a hard starting reliable battery is one less thing to worry about.

5 by

works great. for big block 120R ultra

0 by

Battery measured 12.0V and 25% capacity after charging for one day using commercial quality equipment. Bad battery--wouldn't risk another.

5 by

I have a custom built 131ci motor with compression reliefs. This battery will actually start the bike without the reliefs, that’s impressive. I had to switch the cables from side to side to get it to work. 2004 FLHRSI

would not fit my bike, web page and catalog said it would

5 by

This is the battery all Harley s need!! Even with a hot engine there is no hesitation to start

3 by

Returned, this is not the battery pictured. Order carefully.

5 by

Battery is rated BEST. However the information pertaining to the battery from JP was wrong in every way. Luckily I had already researched with Big Boar. My trust in JP is dwindling.
