We make about 300 million batteries a year. We try very hard to make a battery that is consistent and will last a long time. The most important thing you can do is return the battery with packaging to us. We take issues like this seriously and investigate every problem that we receive back. Rayovac wants to understand whats causing the problem, as this is the only way we can make improvements to the product.
