Car batteries last longer in cold climates than in warm. Cold starts put a greater demand on batteries, but heat is a big factor in car battery life. We can test you battery for how well it holds a charge and to estimate how much life it has left. At MARSHALL'S GARAGE INC. in New London we install quality NAPA replacement parts.
