BATTERY CARE AND MAINTENANCE (CONT.)
BATTERY STORAGE
INSTRUCTIONS
Fully charge batteries
before placing in storage.
As these batteries will self
discharge, we recommend
that they be recharged
after 3 months of storage.
Batteries removed
from storage should be
recharged prior to placing
back in service.
When not in use, store the
charger indoors in a cool
dry place.
MAINTENANCE
AND CLEANING OF
CHARGER
Very little maintenance
is required other than
protecting the charger from
damage and weather.
1. Coil cord when not in use.
2. Clean case and cords with
a slightly damp cloth.
3 . E x a m i n e c o r d s f o r
damage periodically and
replace if necessary with
manufacturer approved
parts.
BATTERY TIPS & PRECAUTIONS
1. Keep the battery charged! The most frequent cause of
battery failure is not recharging after each use.
2. Extreme temperatures kill batteries. Avoid storage
in exceedingly warm, or cold areas. Recommended
operating temperatures are between 5 and 35 degrees
C (maximum - 15 to 50 degrees C). The energy
available on a given discharge cycle decreases at low
temperatures and increases at higher than normal
temperatures. Increased temperatures increase the
gradual processes of very slow corrosion which normally
occur in all lead-acid batteries.
3. Avoid heavy vibrations or shocks, which may cause
internal damage. Foam packing is cheap insurance.
4. Avoid contact with oils or solvents which may attack the
battery case (ABS plastic resin). Clean with soap and water
only.
5. Do not crush, incinerate or dismantle the battery. The
electrolyte contains sulfuric acid which can cause
serious damage to eyes and skin. Dispose of old
batteries at a battery recycler.
6. Do not leave battery on charger for extended periods of
time when battery reaches a full charge.
When using a lithium battery, Attach the multicol-
ored lithium adapter (part # 10791) to the battery
and attach the red and black connector pair from
the adapter to the red and black connector pair on
the LR-20B.
