can get the one for just atvs for like 50 which is half the battery i destroyed, i got the one you can do everything with, have alot of different toys that all need charged in the winter from not being used, alot better for the battery than starting the machine once in a while. i got the 4300, you have different modes so you can use it on all the toys and was 75, figure its a good investment, have like ten batteries and 8 are around $200 with the cold weather cca ones you have to buy around here
