The battery posts were on the wrong side for the VTX 1300s

4 by

It works

5 by

Awesome price received it fast and exactly the day it said I would appears to be great quality and came with all fasteners needed

5 by

havent installed it yet toooooooo much snow

5 by

Seems to be ok. No problem installing and the wires had just enough room to connect to the battery. Installed on 2005 Harley Custom 1200C.

5 by

Exact fit and was delivered in a timely manner

5 by

First battery was defective. As always, J&P took care of it promptly. The replacement battery was excellent--cranking amps are good. J&P is the best company to deal with I've ever encountered in any field of endeavor.

5 by

Just one click and your ready to go

5 by

Great battery fits a 06 sportster good too.J@P is great as usual .They even included a new battery tender fused harness with my purchase.UPS shipping is horrible but it's not J@P's fault.

5 by

My battery was 7-years old and it was time for a new one. J & P Cycles hooked me up with a Milwaukee Twin replacement battery for my 2008 Sportster 1200 Custom. Can't beat J & P Cycles for selection and price. Being a Gold Club member helps save even more money. The phone "reps" are really good at helping with my orders too. Thanks. The new battery is a good fit and works fine! Kendall H. Onalaska, WI.

The one I bought lasted 7 months. To j&PS credit they ll replace it if I have it tested to prove it is bad.A bad battery replaced by another is just not the way I wanna go. Spend a few $ more for a YuĆ sa

4 by

Battery appears to be of good quality. Cranks my S&S stroker motor without any problems.

5 by

Nice battery, came with a charge on it so I just bolted it in and fired the bike up. No messing with acid packs or anything else which is always a plus.

3 by

Seems like a good battery, but the battery posts were on the wrong side for my '82 FLHP.

5 by

Perfect fit. I was pleasantly surprised that it came with a connection for a battery tender also. 1991 Electro glide with 110 motor.

5 by

very strong

5 by

Got it fairly quick for as far as it had to come

5 by

Fit perfectly and included necessary hardware to make connections. Left old battery for J&P to dispose of. Will wait and see what the life of the battery will be.

5 by

great price

4 by

Good strong battery. Works as it should.

5 by

fit right and works very strong..

5 by

Bought this battery 2 yrs ago. Previous battery didn't have enough amps. Didn't have the longevity I had expected but I will still say worth the money. Fired up every time. Till I sat the bike for 6 months

4 by

Priced well within my budget.

5 by

Working very good. Glad i bought it from JP Cycle.

3 by

Not quite an exact replacement. Biggest issue was terminals are not threaded. Need to find a way to hold the nut in place while bolting the wires on. Not easy when battery is in the bike. Also, terminals not flush with front edge of battery. Had to bend starter wire leads to make them flatter. They have a 90 degree bend while attached to OEM battery on Electra Glide, and couldn't be attached without bending.

5 by

My bike 2004 Ultra Classic starts better now than it has in years.

5 by

Worked out great. Fit right in. Bolted right up.

5 by

Fit very good in my 08 Ulta clasic, cranks up better than the OEM battery. Time will tell how good of a battery it is. My OEM battery made it 8 years!

5 by

you guys are really good. I like what I see & buy. Thank you.

5 by

Great battery and even quicker shipping made the down time just a couple of days. Once the battery was installed, the bike started on first try without charging before hand.

0 by

I absolutely hate these posts. They are not the solid posts like on a stock Harley battery but the hollow, flimsy squares with the floating nut. On my 2011 ultra glide, the wires do fit up properly and the bolts supplied to not reach. I had to use ear foamies to push and hold the nut to the top in order to get the bolt to engage.... and this was solution after an hour's worth of trying. No battery should be this hard to install.

5 by

This battery is so much better than stock! Easy left handle to place it in and makes it easy to remove. I will get this battery again! Thanks J&P

5 by

cranks over great

5 by

very good battery and the price was excellant too. Very fast delivery. Very pleased with overall transaction. I will be back!!!

5 by

Great fit, price and free shipping plus it's a strong battery, very happy with the whole process and battery really cranks the engine over! Thanks for a great deal

5 by

perfect fit on '07 streetglide,easy to install and mad crankin amps.not to mention more than $50 cheaper than from local Harley dealer.

5 by

Best deal for a battery. Came charged up and with all hardware and new charging harness. Harley battery is $170.00. Milwaukee Twins is 124.99 and had free shipping. 2004 ElectraGlide never started so fast. JP Cycles came through again!

5 by

Vary good battery so far and quick shipment from jp

4 by

Good price, arrived in two days. The top mounted handle fold down makes easy to get in and out. Had it two weeks, so far so good.

5 by

Love the battery great cranking amps

5 by

Plenty of cranking power. Fit right in, included terminal extensions and bolts to match the battery cables of my Roadking.

5 by

perfect fit, ready to go!

5 by

Great deal & fast shipping. I'm always happy with J&P Cycles.

5 by

Fast shipping and works great. Direct replacement

5 by

perfect fit, better price than HD and I like the handles

5 by

work really well.

5 by

Works great. Not happy with post location.

5 by

like battery fit right in the handle on the battery is sweet

5 by

Great battery, my second, this one for a friends bike. Mine has been in two years, no issues, starts strong. Price can't be beat.

5 by

Great Battery at reasonable cost. $70 less than H-D dealer. Super fast shipping - less than 24 hours. Lifting handle is very convenient. Generic battery posts are time consuming to hook up and require slight bending of terminals.

5 by

Friendly service perfect match plus bonus trickle charge jack included in battery box. I would recommend to anyone.

5 by

Great product, great service. Battery came fully charged ,was a perfect fit, and was an amazingly fast delivery. Made my ride to Biketoberfest possible. Thanks again guys, you make spending money fun again :)

5 by

Powered bike right up fit was perfect and now just need a tender to keep it charged through winter.

5 by

Cheaper than Harley Davidson's batteries and it worked just as good.

5 by

Was just as good as the way more expensive HD battery. Got me back on the road quickly and staff was fabulous!

5 by

Fast delivery and good product, Excellent!

5 by

Great product

5 by

Got battery fast and it was ready to drop in bike. No charging at all and bike cranked right up. It's kind of challenging because of limited working room and short battery leads to get leads attached to battery but, I wound up putting a balled up piece of paper under terminal to hold nut in place so bolt would go through. Overal I think it was a good deal and we will see how long battery last.

5 by

Love me some J&P ! My gear got here fast. My bike started right up. They even threw in at no charge a battery tender with my battery purchase. And the J&P stickers that I love to put everywhere. You people there must love to ride too. Keep up the awesomeness. Thank you,

5 by

Great battery, great price. I saved $60. over my local Harley dealership price!

2 by

Sluggish starts lasted one season

5 by

Rode by the local HD and they wanted $185 (non-negotiable), went home and ordered the Milwaukee. Fired my scoot up from install! Great battery, even has a fold down handle on top...great for getting it in and out. Highly recommend!

4 by

The battery fit right in like the factory battery. The only problem I have with this battery is the top mount slide in nuts, they suck. If you have big fingers they turned a 15 minute job into a 30 minute job. I had to place a piece of birthday candle under the nut then screw the bolt in.

3 by

Lasted 2 years . Kept battery buddy on in winter in heated garage . Ordered another one but think I'll just take it out this winter

5 by

bike started up right away. good buy so far.

3 by

It's warranted for one year and that's exactly what I got out of it. Nothing more nothing less. My harley battery lasted 5 years.

5 by

Very Nice! This battery fit like a glove; It also has a handle to put it in or take it out. The last two did not, making it a little hard to get out. Great Cranking power, better than the last one I had. Fast shipment as well.

5 by

Battery is the right size, but I have to send it back. The terminals are set back on the battery and I needed them flush with the battery case. I tried to bend both positive & negative to fit but to no avail. Both wire bundles to are bulky at the end of each not allowing much wiggle room. You have to pay more attention to the details folks...

5 by

prompt delivery on this battery. exact fit for my 07 Road King. even sent a new pigtail plugin for the trickle charger. will remember J&P for future needs.

5 by

Perfect fit, so far, so good

I bought this battery to replace the OE in a 14 Limited. After I ordered it did I find out that the OE was 405 cca and this one is 385cca. Normally 20 degrees is my limit for riding because I cannot trust the bike will start below that temp. But with this battery last winter I soon raised my threshold to 30 degrees. The battery has been in the bike now for 11 months and last week at 37 degrees; it did not give me much hope to start at any temp below that. If you do not ride during the winter this battery should work well for you. But I am looking to replace it now before winter gets here.

5 by

Great! Arrived fully charged at 12.8 My old battery was difficult to pull out of my FLHTK, but this Milwaukee Twin has a built-in handle which will come in handy a couple years from now. The posts are not that easy to work with - the answer (as always) DUCT TAPE! :) It is difficult to get the bolt to grab the nut (parts included) as the bolt was not quite long enough to grab it. I rolled up some duct tape as narrow as the nut. Stick it on the nut and put in in place. That way the nut is elevated a bit, and stays where you want it. Screw down the bolt, pull out the tape and start your bike!

4 by

I Installed this Battery in a 2015 CVO Street Glide, The Battery is a perfect fit and works great, the only reason I did not give it a 5 star is because the bolts are a little tricky to get started into the nuts with the battery cables, I had to use a plastic tie slide it under the nuts to hold them closer to the top so the bolts could get started, then slid the ties out afterwards. But that was a minor event. The staff was very helpful in helping me pick the correct battery. I would order this product again
