So my Trailblazer is an 04' model... In those almost 4 years I have owned the atv, I have replaced the battery once. The battery that came on it went bad and wouldn't hold a charge, so I went to the dealership and got another. This one wont hold a charge anymore.... I have a tendency to let the battery sit then charge it up and use it whenever I need it... I have heard that I do not have to run it just use a trickle charge once every week. I work at autozone as an after school job so I can get 20% off the battery although price is not a big deal.... I just want a battery I can depend on. And I am going to run this new battery or at least trickle charge it more frequently... But my question is, should I buy one from the dealer or autozone? Also if I get one from autozone, should I get a prefilled (maintenence free) battery or a battery you must fill with acid? Once again I am not worried about price just better quality....

 

if your not worried about price, just buy a new one every year! I have heard the maintenence free ones are better, the trickle charge is a good idea. I use the trickle chargers on my son's little ones
