The MC9500-K is equipped with a memory backup battery which automatically charges from the fully-charged
main battery. When using the MC9500-K for the first time, the backup battery requires approximately 36 hours to
fully charge. This is also true any time the backup battery is discharged, which occurs when the main battery is
removed for several hours. The backup battery retains RAM data in memory for at least 15 minutes (at room
temperature) when the MC9500-K's main battery is removed. When the MC9500-K reaches a very low battery
state, the combination of main battery and backup battery retains RAM data in memory for at least 48 hours.
Charging Temperature
Charge batteries in temperatures from 0°C to 40°C (32°F to 104°F). Note that charging is intelligently controlled by
the MC9500-K.
To accomplish this, for small periods of time, the MC9500-K alternately enables and disables battery charging to
keep the battery at acceptable temperatures. The MC9500-K indicates when charging is disabled due to abnormal
temperatures via its LED. See
Powering On the MC9500-K
