Charging cycles:
The charging cycles of our new battery chargers were developed specially for optimisation of the charging
of all commercially available batteries. The range of dierent technologies employed in the batteries com-
mercially available today require dierent charging characteristics to ensure correct and complete charging.
The JMP Skan chargers extend the life of your batteries as they guarantee the right charging cycle for each
type of batteries.
1. Analysis “A1” Voltage test. The next phase starts at above 6.5 V (Recovery: 2.5 V).
2. “Starting Ch” precharging
Charging procedure with constant current until a voltage of 13 V is
reached.
In Recovery mode only: Prior to the precharging, a higher voltage (15.5.
V) is forced and the charging current increased in order to recover the
battery capacity.
3. Analysis “A2”
(Not applicable to Recovery
mode)
Search for possible short circuit. The charger interrupts the supply of
electricity for 5 minutes. If the voltage drops below 11.7 V during this
time, the charging is cancelled. If not, phase 4 begins. In case of a
short-circuited element or sulphatisation (Er02), charging in Recove-
ry mode is recommended.
4. “Bulk” intensive charging Charges the battery to the dened maximum permissible value.
5. “Stable” constant voltage. The battery is maintained at the end-of-charge voltage.
6. Analysis “A3” Final voltage test.
7. “Floating” buer The voltage drops to the maintenance level and the charge is com-
plete. The green Full LED lights up.
8. “Pulse” pulse charging cycle Battery trickle charging via current pulses (for extended periods of
time).
