Great Little Battery...Its less expensive and has the power! My larger ATV fired right up after a bad cell had me thinking it was worse than just a battery.
Perfect fit for my jumper pack. Came fully charged and in only 2 days. Will buy again.
Fits perfectly and works as advertised

Perfect Fit!
12 volt marine battery would not hold up to a load after 13 months use. Bought these 2, 6 volt set up in series to handle the load when needed. So far working great.
Bought this battery on Amazon

It was 22 Amp Hr so I am trying this one

I ordered a 12V-22ah Mighty Max battery from Amazon. The battery was for my Xantrex compressor/booster. The battery was fully charged, the packaging was perfect and it was delivered overnight! It fit my 10 year old booster pack perfectly and now it works like new!
