    TAllen –

    This battery came to me quickly and with almost a complete Charge, took only 10 minutes to boost it to a full charge. I put it in my Lark Scooter and away I went. It preforms like it should, better than the original battery! Thank You Mighty Max!

Love mighty max batteries

Arrived well packaged. No information as to original warranty coverage and term, but lots of solicitations to extend the warranty coverage for a whole amazing 90 days - Wow, such product confidence! At least it’s not made in China, but is Thailand any better for quality manufacturing? We’ll see.

I received my battery from Amazon on March 9, 2026. The box was a little squashed but the battery was packaged well and it it fine. I installed it and finally my gate opener is working properly. I purchased 2 batteries before this and had to return them because they were the wrong battery. This one is working great.
