4517 Manhattan Rd SE, Calgary, AB T2G 4B3. 2 minutes away from Modern motors ad 4wheel parts.
Great selection of all things battery and battery related.
I was looking for T105's, a deep cycle 6V for my trailer. They had them in stock and gave me a really good price on them. There CJA price on Genius chargers is close to Canadian tires sale price on said chargers.
They also carry a bullet proof line of automotive battery, buggered if I can remember the brand though.
Best bet is to give them a call or shoot them an email. They will reply quick.
