    Worked great to replace the batteries in my APC SmartUPS 2200.

    I used this for my kids power wheels. It last a long time in comparison to the battery it came with stock. Kids can now ride it for many hours. Just had to cut off the factory plug on the car so it can be connected to this battery.

    Fully charged when received. Measurements are accurate for overall size and for terminals. Have not installed (seasonal outdoor equipment – chipper shredder vac electric start) so cannot comment on holding charge and recharging and starting capabilities, but do not expect any problem with sealed lead acid battery. Hope to have 7 years of good use out of it. I do store it indoors between seasons.

Mighty Max Battery
Based on 5566 reviews
Great Price very reliable
This is my second Mighty Max battery. The 1st one is 7 years old and still working. Great battery for the price. Great packaging and fast shipping.
Fixed the ups!
Ordered via eBay. Very good pricing. Arrived promptly.
Installed when my old one beeped (as it was out of charge) & replaced with the new Mighty Max. Works like a charm!
Hopefully it will last 7 years like your last one!!!
I’m pleased with these batteries. I purchased them from Amazon. I’m using them on a razor 24v mx350 electric e bike and they are working great. I stepped up from the original 7 amp hour ones to these that are 9 AH.
It had great packaging. I hooked it up to my 2016 Hyundai ELANTRA has started right up. I would recommend to anyone with this battery size.
Ya van varias pilas de esta marca que compro.para.mi carro son execelentes
Chegou perfeitamente e bem embalada
I use the Mighty Max YTX14AH-BS battery in my 2016 Polaris Sportsman 450 HO EPS. It has a high-power-draw winch and snowplow, and quite a bit of auxiliary lighting. Despite these heavy electrical loads, these Mighty Max AGM batteries perform very well, even in our challenging Wisconsin winters.

FWIW, I am never going back to a flooded ATV battery! These are a lot easier to install, being sealed and spill-proof. It also like to add that the packaging to battery was delivered in was very heavy cardboard with padding inside... it protected the battery well in transit.
