Handling Precautions 218 Long-term storage • Store battery packs in a dry place at temperatures no higher than 30 °C (86 °F). • To extend the battery life of the battery pack, deplete it completely before storing it. • Charge and deplete all your battery packs fully at least once a year. Always attach the battery terminal cover. Do not allow any metal objects to touch the terminals (Figure 1), as this can cause a short circuit and damage the battery pack. Attach the terminal cover whenever the battery pack is not being used (Figure 2). The battery terminal cover has a [ð]-shaped hole. This is useful when you wish to differentiate between charged and uncharged battery packs. For example, with charged battery packs, attach the terminal cover so that the [ð]-shaped hole shows the colored label.
