About Battery Storage
The ideal storage environment is normal room temperature or slightly below. Excess temperature
shortens the battery life and accelerates self discharge. Charge batteries at least once per year or
sooner if needed. The battery open circuit voltage should not be allowed to drop below 12V.
Battery Test
You must use RadioShop 3.4 or higher to run the battery test. See the applicable
RadioShop Getting
Started Guide
for information on using RadioShop to test the concentrator battery.
The new Autoranging power supply (25-1008 or 25-1025) can be software-enabled into battery test
mode. Disconnect the battery charger from the battery to place a load across the battery. Measure the
battery voltage before, during, and at the end of this test to discover bad or weak batteries. This test
is more effective than measuring the battery voltage without a load on the battery.
All Series IV (and Series III) radios will have this capability. The Series II and IIb may have this
capability if retrofitted with kit, P/N 45-1029 (other kits may be available).
Recycle or dispose of batteries properly.
Do not mutilate or dispose of batteries in fire. Fire may release toxic
materials from the batteries.
Short-circuiting batteries may cause burns.
