Care of the Battery Pack
Battery Charging
• Charge battery pack fully before first use to ensure optimum performance.
• Full battery capacity will be acheived after 2 to 3 full charge / discharge cycles.
• Use only SKC approved charger designated for this battery pack. Use of a non-SKC approved charger
may impair battery performance or even cause irrepairable damage, and will invalidate the battery pack
warranty.
Battery Performance
• Charging temperature - For optimum performance charge NiMH batteries between 0 and +45°C.
• Do not overcharge - For optimum performance disconnect battery pack from charger after 24 hours.
• Discharge temperature - For optimum performance discharge NiMH batteries between -10 and +45°C
(refer also to pump specifications on pages 6 and 7 for other limitations on operating temperature for
intrinsically safe applications).
Battery Maintenance
• Battery cycling during regular use - To maintain optimum capacity during regular battery use, cycle battery
once a month. Run pump until low battery shutdown occurs, then fully charge battery.
• Long term storage and highly infrequent use -
1. Charge battery fully prior to long term storage. Disconnect battery pack from pump.
2. Store in a cool, dry place at temperature between 0 and 30°C.
3. Recharge battery at least once a year (or more frequently if stored at temperature above 30°C).
4. Cycle battery 2 to 3 times after long term storage to restore optimum capacity.
