RECHARGEABLE BATTERY GUIDE
Tips - To Prolong the Life of Rechargeable Batteries
Always charge the batteries before first and after use.
Always store portable system with batteries in a fully charged condition.
Always power off the portable system and transmitter/mic when NOT in use.
It is OK to leave the system plugged into a power outlet when not being used for a long
time. The built-in automatic protection circuitry will auto shut-off when fully charged. It
will not harm the system or the battery.
Fully charge the system at least once every 3 months. Battery may not charge if not
charged for a prolonged periods of time.
Store in dry, cool place away from heat. Elevated temperature reduces longevity.
CAUTION: DO NOT recharge other types of batteries and connect a battery's negative
terminal to another batteries positive terminal. An explosion and/or a fire could occur as
a result.

MA-808). Plug into a power outlet to re-charge ASAP.
Q: Average Life Span of Sealed Lead-Acid Rechargeable Battery?

life is determined by temperature, depth and rate of discharge, and the number of charges
and discharges (called cycles).
