Max Life Battery - ML18-12 - 12V 18AH Rechargeable Battery for Champion Generator 9000 7000 - ML18-12ALT53

does what I wanted it to. Stays charged longer than the original. Stronger start.

Works great haven't got to use it much but I am building a cabin this summer and I am sure I will put it too use

Would buy again. Amazingly inexpensive. Keep your wet cell batteries on a conditioning trickle and they'll last years.

very good
