"After comparing prices for 12v 20ah SLA batteries from here to China, this is the best deal going. Hands down. Many companies will soak you for extra $ on the shipping costs. Canadian Batteries doesn't add a penny to Canada Post's cost. Great concept. Too bad most every other business soaks you where they can. The spec sheets made available, are incredibly detailed and extremely helpful. Awesome all around!"
