Chapter 2 M6 Batteries
Non-rechargeable batteries will start to drop in
voltage as soon as they are put into use and then
steadily diminish in voltage until they die. The
Nicad rechargeable battery pack, however, will
diminish very slowly (plateau) somewhat steadily,
then drop quickly.
Headphone use prolongs all battery life.
Battery life will vary a great deal with temperature,
number of target signals, battery type, brand, and
shelf life.
Alkaline Batteries may be used well into the "Lo
Bat" indication. Rechargeables can not.
Battery Packs are available (#802-7150). It is a
good idea to have a spare set when far away from a
new battery.
Rechargeable Battery
(Optional)
A rechargeable battery system is not standard
equipment with your M6, however, high quality
systems are available.
White's rechargeable battery #802-5211, and
charger #509-0022 are recommended and offer
quick charge and overnight charge options.
Rechargeable batteries deliver fairly constant
voltage until they're nearly dead. If you use them
until they are dead, they will deteriorate more
quickly than if you only use them until their voltage
starts to drop significantly. Rechargeables should be
taken out of the detector and recharged as soon as
you notice "Lo Bat" on the display.
Rechargeable batteries will not provide the same
amount of continuous use as a new set of Alkaline
batteries.
