Hard water in your water supply may be causing poor battery performance.

Metallic impurities in water can affect cell voltages and increase
self discharge, resulting in reduced battery life.

The traditional method to avoid water impurities is
to use distilled water, an expensive and inconvenient proposal.

Using deionized water is a simple and effective way to maximize battery life.
