Chapter 2 MXT 300 Batteries
Non-rechargeable batteries will start to drop in
voltage as soon as they are put into use and then
steadily diminish in voltage till they die. The Nicad
rechargeable battery pack, however, will diminish
very slowly (plateau) in somewhat of a fl at line and
then drop like a rock.
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 (in a pinch) well
into the "LoBat" indication. Rechargeables can not.
When traveling far from home it is always a good
idea to carry 8 extra penlight alkaline batteries with
you.
Rechargeable Battery (Opt.)
A rechargeable battery system is not standard equip-
ment with your MXT 300, however, high quality
systems are available.
White's rechargeable battery #802-5211, and char-
ger #509-0022 are recommended and offer quick
charge and overnight charge options. (QUICK
CHARGE is for USA ONLY. It is not available
on 220-240 volt.)
Rechargeable batteries deliver fairly constant volt-
age until they're nearly dead. If you use them until
they are dead, they will deteriorate more quickly
than if you only use them till their voltage starts to
drop signifi cantly. Therefore, recharge-ables should
be taken out of service and recharged as soon as
you notice "LoBat" on the display.
Rechargeable batteries will not provide the same
amount of continuous use as a new set of Alkaline
batteries.
