    I put these in an old battery powered lawnmower that I bought used. The original batteries were rated at 20 AH, but these are working out fairly well. Shipping was fast, and no problems were encountered.

Excellent
Mighty Max Battery
Based on 4579 reviews
Battery was received from UPS in a beat up box with a lot of dirt and ink stains on the outside of the box. The inner box with the battery was unharmed. This was an Amazon ship and the packaging was not up to their standard.
Battery came fully charged and with more cranking amps than advertised. Looking forward to many reliable battery powered days on my jet ski.
Fits perfect and started the mower first try!
Easy install once I finally got cables off the old batteries!
Exact replacement for (internal battery) my portable battery jumper. Same battery as original except the label.
Free shipping, and delivery was on my porch in 1 1/2 days.
Very fair price.
Thank you!
Arrived in 1 day.
Great battery for my General generator ! Easy install !
I’m happy today! My second Mighty Max motorcycle battery…this time I am gonna try a GEL series.
Arrived quickly and as described
I ordered the Mighty Max Battery that is used as a backup for the Chamberlain garage door opener. Ordering was easy and delivery was fast.
