Recharge (Firmware Version Ue54); Memory Effect Of Rechargeable Batteries - Midland G7 User Manual

Recharge (firmware version UE54)

When you place the radio into the charger cradle, at first the charger makes
a sort of checking on the battery status. In this phase, the led of the desktop
charger will turn on for 10 seconds, then will turn off for the following 10 se-
conds and will switch on again to indicate the charging process.
While the radio is being charged, the led on the desktop charger will be on and
the battery icon on the display will be blinking.
When the recharge is complete, the led will switch off and the battery icon will
be steady and will show all its bars.
The recharging time will depend on the battery level and its capacity. The max
recharging time however is about 14 hours, after which the recharge will stop.
This time is referred to a complete recharge of AA 1800mAh batteries.
This new type of recharge functioning is supplied starting from firmware
UE54. To verify the firmware version of your G7 PRO, just press the CALL
button while turning on the radio.

Memory effect of rechargeable batteries

Rechargeable NiMH (Nickel-Metal-Hydrate) batteries are affected by what
is known as the "memory effect". This phenomenon is associated with a drastic
reduction of battery autonomy and is triggered if the batteries are regularly
charged before being fully discharged and/or are not completely recharged. To
avoid the memory effect:
• When possible, recharge the batteries only when they are completely di-
scharged (until the device turns itself off during normal use)
• Do not disconnect the battery charger before the time indicated for a full
battery charge.
The memory effect should not be confused with the normal battery life, which
is 300-400 cycles of charge/discharge on average. It is completely normal for
operating duty to decrease when the batteries have reached the end of their life;
at this point, you will need to substitute the batteries.
