7.3 Care of Your Batteries
Your batteries include many features to make them safe and dependable. However,
you must care for them properly.
Things to Do:
1. To preserve battery life, batteries should be stored at room temperature. Protect
batteries from extreme high and low temperatures.
2. Use all of your batteries. There is a serial number on each battery so you can
rotate batteries.
3. Don’t leave home without extra, fully charged batteries.
4. Protect the battery connector from moisture, dirt and metal at all times.
5. Handle connectors so as to avoid touching the inside.
6. Batteries should be left in the battery charger and charging when not in use.
7. Rotate the use of your batteries.
Things NOT to Do:
1. Avoid leaving the batteries exposed to extreme heat, especially in direct sun-
light or in a closed car in the sun. The temperature can easily reach +60 to +65°C
(+140° to +150°F) which can damage the batteries.
2. DO NOT drop the batteries or let them hit hard objects.
3. DO NOT let the batteries get wet.
4. DO NOT kink or twist the battery cables.
5. DO NOT force connections to the controller or battery charger.
Once a week: Inspect batteries for physical damage, including the battery cable
and connectors. DO NOT use batteries that appear damaged. Damaged batteries
must be replaced.
CAUTION: ALWAYS recharge completely depleted batteries within 24 hours to avoid permanent
battery damage.
