You can remove a battery/radio from the charger at 

any time without harming the battery, the radio, or the 

charger. When you return the battery/radio to the 

charger, charging is automatically resumed. You can 

also leave a battery/radio in the charger once 

charging is complete.

Maintaining battery life and 

performance

With proper care and maintenance you will maintain 

the performance and life of the battery. It is 

recommended that you:

■

Use only Tait batteries and chargers.

■

Do not expose a battery to very high or very low 

temperatures for extended periods of time. Doing 

so will shorten the service life of the battery.

Very high: above 140 °F (60 °C)

Very low: less than –4 °F (–20 °C)

Warning 

The operating temperature range for IS 

radios in hazardous locations is –4°F to +104°F 

(–20°C to +40°C).

■

Charge the battery at a room temperature of 

between 50 °F and 77 °F (between 10 °C and 

25 °C). This temperature range is the optimal 

charging range.

■

Store batteries properly when not in use.
