the pack no longer delivers the same
amount of work.
● To refresh your battery pack, place the battery
in the charger as usual. The red light will blink
continuously indicating that the charge cycle
has started.
● When the charge cycle has completed, the
light will stay on continuously and will no longer
blink. The pack is fully charged and can be
