3 Batteries and charging
___________________________________________________________
3.1 Batteries
The battery belt is the standard power supply for the RAMAC
X3M/EasyLocator.
Capacity of the battery is 12V/9 Ah. This gives an operation time of 6-8
hours. When the battery voltage has dropped down to 10V the
X3M/EasyLocator will automatically turn itself off. The battery should always
be stored fully charged to maximize the lifetime of the battery. The
X3M/EasyLocator can also be supplied by any other external 12V DC power
source.
The EasyLocator can also be purchased with a specially designed trolley
system. This trolley has a special battery box, designed for Li-Ion batteries.
These are more lightweight while giving the same operation time.
3.2 Charging
The battery charger is an automatic quick charger designed for lead acid
batteries. The recharge up to about 80% of the full capacity goes very
quickly. However, it is recommended to keep the battery charging until it is
fully charged. The battery charger can be left on after the battery has been
fully charged. It then automatically turns into maintenance charging.
The indicator lamp on the charger gives you the following information:
Red = Charged < 80%
Yellow = Charged 80-100%
Green = Maintenance charging
Output 2.7 A, equals charging time between 3-5 hours (80%-100%)
