I just received it and though I have no long term results I was impressed with the terminal hardware, 2 short & 2 long bolts, 2 spacers, and 2 lock washers, all stainless steel. I'm comparing this to a recent high output battery purchase from J&P that just can't compare. You get what you pay for. The positive post is on the right when looking at the front, opposite from the high output battery. I have the J&P 5 quart wrap-around oil tank and it's a perfect fit.

Superior power, starts on first fire!

5 by

Great power, worth every penny!

5 by

put it simply/ it works

I purchased the 250 Big Boar in 2002. At the time, I lived on Okinawa, Japan; a hot and humid island and used the battery nearly every day for 3 years. I moved to Michigan where the winters are long and hard. I used it there for 3 years. I have since moved to Hawaii, and the battery has just now started to fail. Seven years of hard use and bad climates and the battery never let me down. I am now purchasing a 350 as a replacement with no fear.

5 by

This thing is a beast! by far the best purchase i have made for my bike!

5 by

Only had for about 2 months - seems to power up starting very good. Will continue to monitor.

5 by

Fiit perfect and seems really well made

5 by

having owned a large bore S&S engine (113 cid) since 1998 i know that batteries can be a pain in the ***. with that said wish i would have tried this one earlier, it rocks. i have never had the cranking power this battery provides, even on cold days it turns the big engine over with no effort.

5 by

I recently took a 4 day trip and logged 938 miles and had no starting problems, Cold and hot starts were no problem.

5 by

Has more cranking power than my stock Harley battery ever did ... even new.

5 by

Phisically smaller than my standard battery but cranks much better than stock. Excellent product.

5 by

works really well.would probaly have the power to start a diesel engine.Installs backwards tho.Would rather have the BIG BORE name show.

5 by

Best battery I've had in any of my bikes.

2 by

great battery, but housing was cracked when i got it

5 by

I had no trouble getting it in as it was the same size as the old one. The only negative is I wanted the big bore label on the outside edge and Its terminals are backwards!

5 by

Just what I neede for the SS 111

5 by

Excellent battery

5 by

5 by

This fit our '02 FXST perfectly. No issues with the battery posts and they were on the correct sides. make sure you order the battery for your bike! :)

5 by

Outstanding bought one for my friend

5 by

very pleased with service and product

5 by

Works Awesome, Turns over my Jims 131 motor with no problem.

5 by

Great Battery! My bike didn't even start up this easy when it was brand new. I definitely recommend this battery. It's better than the stock Harley-Davidson battery.

5 by

Had one go bad JP replaced it ASAP Thanks for the fast service. Will buy again Rich R.

5 by

Cranks over my 127 big block with 2kw starter without using the comp release but is better using comp releases. Great battery. I hear talk of the terms not in the right place, not true if you ordered for the correct year make and model bike.

5 by

I first one I received had Issues but J&P Replaced it promptly. I couldn't be happier with my new Battery. I have a 107CI S&S motor. This Battery fires it without hesitation.

3 by

This battery starts the bike without struggle. However, the actual height is not what it states in the specs. The specified height is 6-1/16"; the actual height is 6-1/4". As a result, it has to be shoehorned into the battery box on my '07 Dyna Street Bob. Once in, the battery box cover will not go on, as it measures just slightly more than 6-1/4" tall. Specs need to be updated by J&P and fitment re-checked as it simply doesn't fit.

5 by

best battery, night train fired right up after install

5 by

great battery and great j&p service

5 by

works great

5 by

Best battery on the market.

5 by

BEST OUT THERE

5 by

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 !

5 by

best cranking Battery I have found for my 93 inch shovel

5 by

its a new battery and works great

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

0 by

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.

4 by

Battery doesn't fit quite as well but does the job.

5 by
