The replacement battery is slightly shorter and the posts are a little lower than the original but because it comes with new bolts for the posts you can make it work. I put one layer off a roll of foam made to seal a 2×6 wall onto concrete on the bottom and end of the batt. – plus another layer (cut to fit ) the end. The end plate then held it in snug in the batt. box and I took the flat washers from the old batt. bolts and added them to the backside of the cables . Works fine ! – Batt. lays flat in my generator -B&S 7000

Excel 8000 generator.
Lynn Macumber –
Ontime & as ordered
Bradford Evans –
My generator’s battery had seen its last day and with winter just around the corner, if the power goes out – the generator is the safe guard. The battery was an exact fit and the price was great.
Jim K. –
Perfect size for my generator (Briggs/Stratton XL 8000-13500 start) and stronger than the battery it replaced.
Eric T. –
Great
Charles Cates –
It is the correct size and fit for our generator.
23Trader –
Great fit with the proper terminal configuration
Jerry Oyster –
nice battery exactly like old one.
Web Customer –
The criteria for the survey is vague at best. It’s a battery. It’s expensive, no way to tell about “longevity” and it’s under the gas tank…not a picnic to install. All said and done, it does what it’s supposed to. It starts the generator. And does it very well. Good purchase.
N Power –
After a month wait it finally got here. Hooked it up and it started generator right up, without a charge, straight from the box.
Gabriel G. –

Iowa Farmer –
Purchased this battery to replace a battery in a generator. It was a direct replacement. The posts were correct. Time will tell if it will last as long as the original.
Steve –
The battery fit perfectly and came charged. It starts the generator with no problem so far.
Daniel Womack –

Glenn –
Form, fit, function as advertised. Be careful: make sure to get the correct type and orientation of the terminals.
J. Morse –
This was a direct fit replacement for my generator starter battery – was fully charged right out of the box and solved my generator starting problem.
Diego Miranda –
Todo fue bien la intalacion perfecto todo
Dan L –
Fit perfectly in my PowerBoss 7000/12000 Watt generator. Works perfectly. Only gave 4 stars on longevity because it’s only a couple weeks old. If it lasts two or three years (the previous, original one lasted 10 years), I’ll be perfectly happy and, if I can, I’ll up the longevity ranking to 5 stars.
Golden Girl –
Needed a new battery for generator. Right size and fits.
Customer –
OK, so it’s a battery. Impossible to determine what its longevity will be. This one was a perfect fit, came fully charges and was easy to install. The generator turned right over. The battery that came with this generator lasted over 10 years and was always on a maintenance (trickle) charge. So we put a new trickle charger on the new battery and we’ll hope for the best. We test our generators periodically to know they are ready when we need them. We’ll update this review as time goes on and we have more information.

Pat G –
I replaced my original cp12180xrp which lasted six years with mighty max because it was less money and shipping was included. The oem one is still available but reading the reviews for the mighty max i thought this is the best deal. Shipping was four days got it tested the volts 12.9 out of the box. The picture matches the terminal location. The width matches the depth matches the height is 1/4 shorter then they list. Installed it started my briggs elite series 7500watt generator started up easily in Ct and its 13 degrees f outside. Time will tell hope to get six years again but three to five would be normal for a battery of this type. Four stars because like i said time will tell. Update after 15 months 3/25/2019 battery is still going good.

Gene L. –
The battery is great. But the post polarity was reversed. I had to make some changes to allow it to work. I didn’t get what I ordered. But i was able to make it work with some modifications. Therefore I can’t give it 5 stars. Only 4.

Mike –
Exactly what my Briggs and Stratton 13500 generator needed. The reverse polarity made installation exactly like the original. I’m sure I could have made any battery of the same size fit by rotating it, but it is nice to have the exact replacement.
