Operation Manual
Figure 53: ET1 Battery Charging
Charge batteries in temperatures from 0 °C to 40 °C (32 °F to 104 °F). Charging is intelligently controlled by the
charger in order to ensure safe operation and optimize long-term battery life. To accomplish this, for small periods of
time, the charger alternately enables and disables battery charging to keep the battery at acceptable temperatures. The
charger indicates when charging is disabled due to abnormal temperatures via the Charge LED. See Table 9: Battery
LED Charging Indicators on page 84.
