where to get a new battery in toronto?

Interstates are made by Johnson Controls and are possibly (probably?) the best-built available overall. Other sources for JC batteries are everywhere. Sears is probably most universal. If you weren't satisfied with the one you had you'll need to figure out a way to shoehorn something with higher capacity into the hole and/or make sure that your charging system and all your wiring are top-notch so that you can actually use all that the battery is capable of. -BaH

oh, i know the wiring is not the best. one of my projects for this summer is to check and clean every connection. i was not aware that interstate are the best. i will try another one.
