Battery Maintenance (in storage)
Follow these procedures for maintenance of battery on a machine not in use:
• Keep battery clean. Electrolyte of batteries should be checked regularly and kept at proper
level.
• Never stack one battery directly on top of another because post or container damage can
result. If batteries are stored individually, place supporting boards between layers. Rotate
stock so that the oldest batteries are used first.
• Batteries should be kept fully charged. A battery, while in storage, should be recharged to
full charge at recommended intervals.
A battery fully (100%) charged at 80°F (26.6°C)
- drops to 65% at 32°F (0°C)
- drops to 40% at 0°F (-32°C)
