SRS Labs SR560 manual Operation And Controls, Warning regarding battery maintenance

OPERATION AND CONTROLS

•AVOID DEEP DISCHARGE

Recharge the batteries after each use. The two-step fast-charge / trickle-charge operation of the SR560 allows the charger to be left on indefinitely. ALWAYS recharge the batteries immediately after the BATT indicator LED on the SR560 turns red. Built-in protection circuitry in the unit removes the batteries from the load once a dead-battery condition is detected. Avoiding deep discharge will provide the longest battery life - upwards of 1,000 charge / discharge cycles.

•AVOID TEMPERATURE EXTREMES

When using battery power, operate the SR560 at or near room temperature. Operating at lower temperatures will reduce the capacity of the batteries. As well, more time will be required to recharge the batteries to their rated capacity. Higher temperatures accelerate the rate of reactions within the cell, reducing cell life.

•KEEP THE BATTERIES COOL

When not in use, the SR560 should be stored in a cool, dry place with the batteries fully charged. This reduces the self- discharge of the batteries and ensures that the unit will be ready for use when called upon. A SR560 in storage should be "topped off" every three months with an overnight charge to maintain its batteries in peak condition.

Warning regarding battery maintenance

Batteries used in this instrument are seal lead acid batteries. With usage and time these batteries can leak. Always use and store this instrument in the feet-down position. To prevent possible damage to the circuitboard, it is recommended that the batteries be periodically inspected for any signs of leakage.
