Preparing the Power Supply
• Charged battery packs continue to discharge naturally. Therefore, charge them on the day of use, or the day
before, to ensure a full charge.
• We recommend that you prepare battery packs to last 2 to 3 times longer than you think you might need.
• To charge the battery pack, disconnect the DC cable from the compact power adapter.
