Storing a fully charged battery for more than three months in a location that exposes it to high temperatures (above 70°F or 21°C) can signicantly reduce its recharging capacity. • Before storage, charge the battery to approximately 50% of capacity and store it in a cool, dry location where temperatures are not expected to exceed typical household levels. • Do not store a fully depleted battery because it may not recharge after an extended period of storage. • After storage, fully charge the battery again before using the DC 40.From the main menu, select Advanced > Settings > System > GPS > Battery Saver.
