• Ensure Nickel-based battery packs are fully discharged (as indicated by the radio low battery
warning) before re-charging. Full discharge is not required for Lithium battery packs.
• Periodically condition Nickel-based battery packs. The frequency should be determined based on
usage patterns (refer to ECR-7367). If the battery is fully discharged (to radio Low Battery warning)
during routine use, the frequency of conditioning may be reduced. Lithium batteries do not suffer
from memory-effect and therefore do not require conditioning.
Do not leave any Harris rechargeable batteries in a charger for more than a few days.
5.4 CHANGING THE BATTERY PACK
5.4.1 Removing the Battery Pack
Make sure the power to the radio is turned OFF.
Although the P7300 has been designed to tolerate changing the battery pack without
turning power off, Harris recommends turning the radio off before changing battery packs
to ensure safety and best operation.
1. Press or pull both latches on either side of the battery pack toward the bottom of the radio
simultaneously.
2. Pull the battery away from the radio.
3. Remove the battery pack from the radio.
