NiMH Battery Packs
Battery Care Tips
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 / full
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 - NiMH batteries can be charged between 0 and
+40°C, but for optimum battery performance the range +10 to +30°C is
recommended.
• 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 documentation
for other limitations on operating temperature for intrinsically safe
applications).
Battery Maintenance
• Battery cycling during regular use - Available battery capacity may be
reduced when battery is only partially discharged during each use. To
maintain optimum capacity during regular battery use, cycle battery
once a month. To cycle battery, 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.
2. Disconnect battery from pump and 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.
