Bike starts right up now.

 carpendl29 Posted:

fit perfect 1993 XL 1200 started right up. is made in Vietnam. square nut and bolt tighten up better than just bolt only to terminal

 hfdfxrs Posted:

Good battery for great price. Plenty of cranking power

 badabing1 Posted:

You need spacers and longer bolts due to the studs being 3/8" INSET from edge of batt. Case mine were flush with batt. Edge and cables come from below , no way to move cables but straight up and you can't do it due to seat, you should supply spacers with bolts with battery !

 markmoon Posted:

Great price.

 jnavin Posted:

Great battery, same size as factory, easy to install. I have had it in the bike for 3 weeks, riding everyday, with no issues so far.

 Willy Legs Posted:

Very good battery so far. It is a bit difficult to rate a battery until there is some time on it, like a few years. But, very strong battery and I am sure it will give me the five years I expect. I am well pleased with the battery and especially the service from J&P

 posttime29 Posted:

Starts every time.

 michaelsndbrg Posted:

Fit great on my 2013 wide glide and it fired right up

 madracing115 Posted:

Have bought these batteries for other bikes and have had no problems. Exact fit.

 DaWolf Posted:

The third battery I have bought like this for customers bikes. No complaints. Comes with a free tender cable which is a nice touch.

 copter2958 Posted:

easy to order, fast shipping and delivery

 hingjawl Posted:

 rodney531 Posted:

 billt5206 Posted:

 tacticaltom Posted:

They are always awesome and helpful.

 sleepingdragon999 Posted:

Priced well within my budget.

 roberthenderson Posted:

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

 facp62 Posted:

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. Posted:

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

 jleonard1 Posted:

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

 MRB29 Posted:

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!

 dolly rios Posted:

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

 Bluesssman Posted:

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.

 hrdfsique Posted:

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.

 Blake30 Posted:

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

 shoveldon Posted:

cranks over great
