PROLONGING BATTERY LIFE
The NiCad “memory effect” occurs when batteries are only partially discharged and recharged repeatedly. This
effect substantially reduces the level of useable charge in the batteries. The batteries can be restored to
maximum usable capacity by discharging the batteries until the meter displays RECHARGE at least once a
month. This can be accomplished at the end of the work week by running the meter continuously until the
batteries run down. The meter will remain on if left in TREND mode. The back-light should be off during the
discharge period. The meter will shut off automatically when RECHARGE is displayed. Place the meter on
charge for at least 24 hours, so the meter will be fully charged for the next week's work.
Long term storage of batteries can temporarily degrade their performance. If the meter is to be stored without
being used for at least three months, discharge the batteries as described above. The temperature during
storage should be less than 95 F. The batteries will function best after storage if reconditioned by performing two
full cycles of 24 hour charge and full discharge, followed by a third 24 hour charge. This process will restore the
batteries to maximum usable capacity.
WARNING: Do not plug in the charger if ANY
nonrechargeable batteries are in the meter.

The EPA certified RBRC
®
Battery Recycling Seal on the nickel-cadmium (Ni-Cd) battery indicates Shortridge
Instruments, Inc. is voluntarily participating in an industry program to collect and recycle these batteries at the
end of their useful life, when taken out of service in the United States or Canada. The RBRC
®
program provides
a convenient alternative to placing Ni-Cd batteries into the trash or the municipal waste stream, which may be
illegal in your area. Please call 1-800-822-8837 for information on Ni-Cd battery recycling and disposal
bans/restrictions in your area. Shortridge Instruments, Inc. involvement in this program is part of our commitment
