— COLD WEATHER SYMPTOMS / AFFECTS LITHIUM-ION BATTERY PACK TROUBLESHOOTING GUIDE CONTINUED —
Charger lights go
out after charging
for a short period of
time.
Battery Pack was cold Charging in cold weather can cause this effect to occur.
Remove/reinsert Battery Pack. If lights do not turn on, unplug
Charger for one minute and plug it back in.
Fuel gauge lights

Pack is placed on
Charger.
Pack is cold while charging If the Battery Pack is cold, charge current is “pulsed” at a slow rate.
This can show up as blinking fuel gauge lights. Wait for green
Charger LED to indicate full charge, or in some conditions, Charger
lights will turn off (see above).
Fuel gauge lights
inaccurate while
charging.
Battery Pack is cold If the Battery Pack is cold, the Battery Pack voltage rises higher than
normal during times when charge current is applied. This can cause
the fuel gauge to read higher than the Battery Pack actually is. This
effect will be more apparent at the start of charge with a cold,
discharged Battery Pack. Wait for green Charger LED to indicate
end of charge or in some conditions, charge lights will turn off (see
above).
Fuel gauge button
does not operate
with Battery Pack
connected to
Charger.
Normal Pack fuel gauge button is inoperable while Battery Pack is on

(4ºC)
Charger reduces charging current at low temperatures. Increased
charge times are normal under these conditions. Move Charger
and Battery Pack to warmer location, if faster charge time is
desired.
Battery Pack Protection – a feature not offered in competitor Li-Ion Battery Packs; damage to these battery
packs can result with an ensuing reduction in their battery pack performance and life.
