We buy batteries first because we need them and then secondly we buy them at the cheapest possible price. Considering that 75% of the world's batteries are made by Chinese manufacturers, regardless of brand then it makes sense to buy the cheapest battery available knowing full well that I will have to buy another replacement battery sooner rather than later. But who cares as long as it is cheap (buy cheap - buy often)! However if I wanted to make a better battery purchase what considerations would I have to factor? In other words how do I buy a battery that gives me the best value for my dollar?
