Too soon to judge its life span, but the battery was fully charged & came with everything for any easy install in my '01 Road King. Gold Club discount was nice too.

NOT much room for the battery on my bike, but this one fit like a glove and I'm up and running good as new. Thanks JP :-)

Sound a little hard starting

good deal,the provided screw hardware sucks,screws are to long

  Posted:

Best value in a battery I could find - cranks it right up.

  Posted:

I know all batteries have to be charged before install but I was surprised at how flat this one was when delivered. Took a full 24 hour charge. Has worked fine since.

  Posted:

Fast shipping and quality battery. Mounting posts and hardware are not ideal.

Battery fit perfect and work on the first push of the start button. Great value!!!

Perfect Fit, Fast delivery,I recommend this product

  Posted:

Being a Gold Member. Shipment- fast, install - easy, service life - TBD. I have had only one instance with a previous order that was rectified in a timely manner. J&P has been my main mail order source for my H-D that is rolling past its 128,000 mile mark. Thanx J&P

  Posted:

Very Happy with this battery. Fully charged right out of the box.

  Posted:

Out standing Battery. So happy with this product. Great price saved me 85.00.

  Posted:

I am very happy with this battery - not only is the fitment right on spot but the cranking power far exceeds that which I had experienced on the battery I replaced even when it was brand new. Highly recommended!

  Posted:

great battery put it on and it was ready,exact fit

  Posted:

J&P battery lasted one season. I gotta buy another one and will be looking at the odyssey batteries.

  Posted:

products great great service and tech support hope everyone has a great new year

  Posted:

very good. cranks bike over fine. fit very well

  Posted:

Best battery I've had in the 10 years I've owned this bike.

  Posted:

good

  Posted:

Battery came fully charged from the factory,worked perfectly.Great Battery

  Posted:

Battery was shipped complete with all hardware, Fits application much better than off the shelf batteries from parts stores

  Posted:

Good battery, fit well, works well.

  Posted:

Great battery

  Posted:

Great headlight and very easy to install

  Posted:

It fit like a glove, and the description was dead on

  Posted:

Only several weeks in use, looking forward to not having to replace it every year. The DieHards just did not stand up to the vibration of a slightly modified 84 FXRT

  Posted:

Fast delivery! Great product! Thanks!

  Posted:

A new battery is always nice. Good fit. Good cranking power!

  Posted:

Quality OK, post connections not the best.

  Posted:

fit just right good price for that battery

  Posted:

the battery works great. I can't remember it ever turning over so quickly. I hope it lasts as long as the original one in my 95 HD-about 17+ years!

  Posted:

Really happy with this battery. I put it in a 1993 XL 1200.

  Posted:

Check your battery box size very carefully. These batteries are a tiny bit bigger. It fit OK but was a tight squeeze going in.

  Posted:

Fits fine

  Posted:

Good quality

  Posted:

So far a good battery, and it fits! Made in the good 'ol USA!

  Posted:

Battery terminals where on wrong side

  Posted:

Slimmer than the OEM battery, but includes rubber spacers to keep it in place. Excellent design on terminals allow for tight fastening without worries of stripping anything out.

  Posted:

Better than Harley and 30 bucks cheaper.

  Posted:

The battery was easy to install and has been functioning excellent. I always had to keep a charger on my old battery just in hopes of it starting without a jump. This battery I was able to install in 10 min and has been cranking strong ever since.

  Posted:

Great Battery - Great Value!!!

  Posted:

Great Product!

  Posted:

This USA Made battery is a superb value. Fits well into my 98 Fatboy. Especially like to connector setup for front mount or top mount. High CCA are unmatched by any other battery I have found for the price. Very happy with this battery.

  Posted:

Great battery and service from j&p cycles. Very pleased.

  Posted:

Great battery and price - thanks...

  Posted:

Great product and a perfect fit. The battery arrives sealed and charged, however, due to time on the shelf prior to its arrival, I had to put it on a 2Amp charge for about 6 hours. No problem, it’s a lot better than putting in the electrolytes yourself.

  Posted:

Battery works just fine.

  Posted:

This is a quality battery. Has more cold cranking amps than the factory stock battery that came on my Harley.

  Posted:

This is a replacement for the OE battery. I have had it for only a few months, but it has performed as advertised. The real test will be if it lasts as long or longer that the OEM battery.

  Posted:

Great battery for the money.

  Posted:

Not real impressed. Even with 1 year warranty, battery died after 1 1/2 years. Original factory battery lasted 4 years!

  Posted:

So far this battery has held up very well. It does have more cold cranking amp than your OEM battery. Impressed with this. In fact I ordered another on for my 2009 HD Electra Glide yesterday. Hope it performs as well as this one.

  Posted:

Great product, I was a little worried because the measurments on the product description on line was not the sam as the original, but it fit my 2006 Fat Boy with no problem. Bike started right up and the batrery came with a full charge already. Good stuff!!

  Posted:

Great product and service

  Posted:

Installed with no problem on my 91 Heritage. Engine cranking power is good.

  Posted:

Fits Form and Function all good seems solid.

  Posted:

Very solid product.

  Posted:

Battery has served me well this summer.

  Posted:

Battery fit with no problem. More than enough power to crank over a high compression engine.

  Posted:

great battery..has cranked a 140 horse engine all year with no problem..has never had a weak charge

  Posted:

Purchased during biketoberfest. Worked great. Allowed my son to keep riding..Never missed a beat

  Posted:

After 10 months, I'm very happy with this. An AGM-type battery from HD is at least $40 more. Our $3000 hi-tech battery tester at work rated it at more than 400 CCA! Good buy.

  Posted:

Quality workmanship and fits perfectly in my 2007 Sportster.

  Posted:

Excellent price and on-time delivery

  Posted:

well packaged and perfect fitment

  Posted:

WORKS GREAT SO FAR,NO MORE STARTER DRAGING & PRICE AN'T BAD EITHER $$$$

  Posted:

Great price and fit my 2002 Sportster perfectly. I am very happy with this purchase.

  Posted:

The AGM battery I purchased from JP Cycles works great. It has lots of cold cranking amps (CCA). Dimensionally it is a perfect fit in my 2000 Heritage Classic. Highly recommend JP Cycle batteries.

  Posted:

Battery is a perfect fit and a quality product.

  Posted:

works great

  Posted:

Great service and easy order entry. Battery is great!

  Posted:

Great to have a part that is made for this bike and not some local parts store faxcimily

  Posted:

Be sure to measure your old battery space very carefully. The new battery I got was a tiny bit taller than the original. It fit OK but was tight going in.

  Posted:

The best AMERICAN MADE, no spill, AGM mat battery you can buy at any price.

  Posted:

Proper fit great price

  Posted:

Product shipped timely, tech support was courteous and knowledgeable of product.

  Posted:

Great battery at a great price. Bettery warranty than most.

  Posted:

Perfect fit for the battery case and cranks my 09' Heritage Softail right up. Great battery!

  Posted:

Good Battery

  Posted:

Better battery than the original

  Posted:

Excellent product, excellent price and excellent service. The battery was $13 less than at HD including shipping. Ordered it on Monday, received it on Wed. The only thing is I wish it had been a week later when there was 10% off and free shipping, but I had to have it.

  Posted:

No problems yet

  Posted:

Bought the wrong battery was a snap to return

  Posted:

Good fit-would recomend battery to anyone looking for a great deal that works great

  Posted:

exact fit, good performance and much cheaper than dealer

  Posted:

Great bang for the buck! Installed in my '91 FXSTC, plugged in battery tender overnight, been good to go since. Cranks my Evo over quicker & fires bike up faster than stock battery did. Fit was good, too.

  Posted:

Great battery

  Posted:

Fully charged when received. Dyna starts right away. Happy with purchase so far.

  Posted:

correct replacement for my battery and it was a lot cheaper then the HD replacement

  Posted:

Very good product for the money!

  Posted:

Nice price and quality

  Posted:

fits perfectly

  Posted:

Looks okay. Time will tell....should be just fine.

  Posted:

Good Job!!!!!!! I recommend J&P Cycles, highly.....

  Posted:

This battery is awesome! My Harley battery was 225 cca, But this baby is 310! Wow, it brings my bike to life in an instant! It came fully charged; no messing around with acid and charging. I just put it on my trickle charger, and less than 5 minutes was fully charged! And you can't beat this price for a quality battery! Thanks again J&P! I love you guys!

  Posted:

Battery came in the precise moment I was expecting it, precisely when the factory one quit. As usual, I am very satisfied with everything I have ordered in the past from J&P and will continue to do so in the future Rafyv Long Beach CA

great battery, good price

  Posted:

battery fit perfect, bike started at the touch of the switch

  Posted:

battery works great, hopefully it lasts a while. the stock battery from HD didnt do too well.

  Posted:

Fit in box well. Didn't particularly care for the post connections but did work out.

  Posted:

Wow! Powerful battery and cranks that engine over NOW! Console lights are twice as bright and no leaking fluid!!! Get this battery; you can't go wrong with it.

  Posted:

Good product nice battery

  Posted:

Battery arrived completely discharged with part of the label missing. Charged it and installed and found that it would not hold a charge overnight. Took it to a shop and it tested bad. Returned for refund.

  Posted:

Working good so far. Like not having to have a vent tube

  Posted:

Good battery, easy to install, fast delivery.

  Posted:

works great

  Posted:

great battery

  Posted:

Waaaayyyyy better than the walmart junk battery I bought last year. I was convinced I had starter problems until I changed to this battery. My bike has never turned over so fast!

  Posted:

Great battery so far after a month. Bike turns over much quicker than the old battery... and got to have a good battery in an Electraglide. :)

  Posted:

Just got battery, looks cheaper then OEM but at 2/3 the price that's okay. It works just fine. If it's as durable and lasts as long then it's a steal. But that review has to be done several years from now.

  Posted:

Works Great, fit perfect and arrived in a timely fashion undamaged. Thanks, Bill

  Posted:

great fit works great

  Posted:

"High Amp" ratings not marked on battery. Came in a nice box, tho.

  Posted:

Hard to find battery only harldey davidson and jp carried in stock. jp was 40.00 cheaper. After charging, put in bike and it has performes as well as the factory original. No complaints.

  Posted:

The battery is not a true bolt in replacement for a OEM battery. It takes some 1/4" brass shims to make it fit my 08 Sportster. It is working fine but long term spacers are just another connection that can cause problems.

  Posted:

Very easy to install with no acid pack to deal with. Fits well.

  Posted:

works great. many thanks

  Posted:

This was a great purchase for my 2009 Sportster. I need the extra amperage in order to turn over my engine at start-up. Thanks very much for your service too. Always excellent.

  Posted:

This battery worked fantasic for me. I got a big name battery a few months ago at a local shop, and it suddenly lost a cell, it was no good anymore. so I wanted to try one from J&P, and it has been great. very good price and shipping time too. got me rollin' again quickly. Thanks J&P!

  Posted:

delivery time was excellent. battery post broke during normal installation. had to return it.

  Posted:

had to make spacers to get correct fit.

  Posted:

good price for good battery

  Posted:

What makes this battery great for the HD Sportster is its size. It is 1/2" shorter than stock sizes, which makes it easier to install since the Sportster's battery cables are ridiculously short.

  Posted:

Nice compact battery

  Posted:

My battery came promptly, fit my bike and was a good price, what more could you ask??

  Posted:

starts up bike very nice. had to use spacers to even up clamp area on battery to get cables to fit correctly.

  Posted:

Good battery! A little smaller so shims are required.

  Posted:

great product at a great price

  Posted:

I bought it for a little hardtail i'm building specs right on .

  Posted:

A lot of cca to start my high compression engine nice fit also

  Posted:

Decent battery. I would have hoped it had solid terminals not the open cube style. So far it has worked just fine.

  Posted:

Thanks, best price, more cca's and quick delivery.

  Posted:

it works

  Posted:

easy to fill and charge

  Posted:

Great battery at a great price, Thanks

Important Product Notes

Note: Sealed batteries are charged at the factory, and while they have a very low discharge rate, all sealed batteries should be charged on an automatic charger before installation.
