    Bought in 12/2018. Worked well for home alarm system, but here I am less than 2 full years since purchased it and need to replace. Will gladly pay a bit more for longer lifespan. Will try Interstate next.

    I installed the new battery, and it was fully charged within 12 hours. I hope it lasts longer than the old expensive one.

    This battery is the second from this maker for different tools. Can’t see a bid of difference in performance that that of factory installed battery with tool was new, but BOY is there a difference in price. Saved over $70 by buying this battery ov er buying a replacement from the company that made the tool.

    I purchased this for replacing an aged APC UPS battery. I don’t know how much different the claimed 5AH is from similar products’ 4.5AH. It’s so far so good.

MM battery a lifesaver!!! Times are rough atm and ofc my car battery starts malfunctioning 🤦🏽‍♂️ every car parts store wanted $260+ for a new battery I thought I was screwed but luckily I found mightymax batteries and was half the cost!! Now I’m rolling again and not needing to break out the jump box 10 times a day! 🤣 thanks again mighty max!!

Purchased to replace handicap scooter batteries. Great packaging and easy registration
Very good experiences using Mighty Max batteries on my bikes and it was time after getting almost 5 years on this one. Shipped quickly and was ready to install. Package was well protected when it arrived. Price is awesome for a quality built battery, you can pay twice the price, but it won’t last longer!
