Storage
Do not expose your battery pack to water or rain; this
could damage the battery pack.
Fully charge the battery before placing it in storage. For
optimum life, store the all Ni-Cad and Lithium-Ion
batteries at room temperature away from moisture.
Permanent capacity loss can result if batteries are stored
for a long period at high temperature, over 120°F(49°C).
Maintenance
When charging or discharging a nickel-cadmium or
lithium-ion battery over a short period of time, the
internal temperature of the battery pack increases
substantially. This is normal.
• Under ideal working conditions the useful life of a lithium-
ion battery pack is around 1000 charge/discharge cycles.
Improper care and maintenance shortens battery life and
the amount of time the battery holds a charge.
• Use only with Snap-on charging equipment that
specifies a CTB series battery pack.
• Avoid short circuiting the battery pack. Permanent
damage to the pack can occur from high current
discharge.
• Unplug charger from outlet before starting the
disassembly procedure.
• Remove the battery pack from the tool before starting
the disassembly procedure. Short-circuiting the
battery pack can cause fire or personal injury.
• Use safety equipment. Always wear eye protection.
