Mighty Max Battery BATTERY RAZOR DIRT QUAD VERSION 1-8 12V 10AH - 2 Pack

Great direct replacement batteries! Have purchased for both our Razor ATV and Razor go cart. Both work great and hold a nice long charge. Only issue, and very minor, is they are slightly taller than OEM Razor batteries requiring longer hold down screws. No biggie though, I was aware of this from an older review and bought a pair of 1.5” long replacements from Lowes (see pic for specs)

So far these things pack a good punch in my sons Razor ATV. I'd like to thank others for posting that you would need to make some minor mods but they would go back in the engine case without any changes. They are a bit taller than the stock batteries and I had some bolts laying around that worked perfect. I had cut some spacers from a wall mount tv kit that filled that space and added the needed support between the battery bracket. Sone took the ATV out and it climbed our hills pretty easy and didn't seem to stress the batteries at all. I will throw in an update if things change, but so far so good. if you even have a slight mechanical inclination its easy to swap the wiring over as well from the old battery set.

Great price for these batteries always trust this brand.

These batteries work as well as the originals, but beware there are a couple of differences. First, they are taller than the original batteries by a half inch or so which required me to replace the screws on the metal bar battery retainer because the original screws were not long enough to allow for the additional height. Also, the height barely fits under the plastic engine-looking battery cover. Second, the Razor wires connecting to the terminals on the original batteries have a rubberized protective layer on the female disconnects which didn't allow reuse. I had to clip off the Razor female disconnects and buy new ones at Lowes to replace. In all, what I thought would take about 10 minutes took a lot longer than I anticipated.

I've been using these batteries in my son's electric 4-wheeler for over a year now. I ride it with him since he's too young to steer it by himself. That's a total weight of 200 lbs (not counting the 100 lbs the 4-wheeler itself weighs). We can ride for around 1 hr at a time with consistant power output until the last few minutes. These are high quality, high powered batteries. If I ever need to by more in the future, it will be these again. I'm very happy with my purchase.

Easy to install, slightly bigger in height needed a little longer bolt for hold down bracket. Battery last a long time because they are 10 amps instead of 7 amps

Most of the issues with installation I was prepared for by reading the existing reviews. The batteries are taller than the original ones but can be accommodated with longer bolts. Transferring the wiring over wasn’t too difficult with minimal knowledge of wiring and fasteners. The performance of the batteries has so far been very good

I've only recently installed this battery; I replaced the factory battery in the quad, which lasted for about 6 months or so until it could no longer hold a charge (weak!). When the original battery did hold a charge, it would last an hour max. These new batteries seem to last at least twice that, from the get-go. Note that I have a rather light 4-year old who rides the quad, so my run times are a bit longer in general than the average sized rider. YES, you do need to solder the connectors on from the old batteries and secure the battery bracket with longer bolts, but it's pretty simple if you're comfortable soldering. Good bang for the buck - I've paid a lot more for much less powerful batteries. I will modify the review 6 months down the road to update in regards to holding a charge. Tip for soldering - the solder on the old batteries needs a lot of heat to be de-soldered; about 800F. Grab a bit of shrink tubing to make nice clean wraps for the new connectors.
