I bought these batteries so I could mow my lawn.. replaced batteries that would no longer hold a charge for more than 5 minutes.. put them in my mower and have held off a review to see how they held up through a winter. I left it plugged in and monitored the charger lights.. rans it a couple minutes at a time through the winter.. so that it's have some actual ion movement... whatever.. The original batteries only worked one summer the next wouldn't hold a charge.. I got these after shopping and deliberating for hours.. I thought these would handle it.. but apparently not! these batteries are 100% junk and wasted my money...they charge up according to the lights on the charger but then I can only mow like 3 swathes of the lawn when they run out of power and bog down and dont work... really makes me angry cause I'd rather have spent all that money on beer instead of a frustrated attempt to mow a freaking lawn... which is only feet by feet... not an acre not a half acre not a...

Hello, went fishing yesterday and used this battery to power a 30lbs. thrust trolling motor. I was on a colorado pontoon kickboat. It pushed me; agains very strong winds; running constantly on high power, with my fins in the water, and did for over 2 hours. I ended up over 2 miles from where I launched. This is battery is worth every penny. It was my first time using it. I had a full size marine battery with me also, and wanted to test this battery. Although it was delivered fully charged, but I put it on the charger for the night anyway. This battery is perfect for small crafts, and for on/off opperation for a day. The only thing left to find out is the life span of the battery, how many chargers it will take. EXCELLENT BATTERY!.

I initially purchased two of these to expand my UPS capacity. I was quite pleased with the purchase and the product; the batteries arrived promptly enough and were packaged in branded retail boxes that were, in turn, placed inside an outer box for shipping. They came with bolts, washers, and nuts for the terminals and the terminals were covered with plastic guards for shipping.

I then decided to add two more to my array and ordered them up. The two that arrived (again, purchased and shipped from the manufacturer through Amazon) arrived packaged each in a single box (i.e., no inner branded retail box) secured with wadded up newspaper. No bolts, washers, or nuts were included and the terminals were uncovered. One battery was damaged (big dents on two corners and the box was torn as if it had been handled roughly) and covered in dirt/dust from the opening in the torn box.

A bit perplexed, I communicated with Mighty Max and they sent out a replacement battery without... Read more
