13. Lead Batteries (Pb)

a) General Information

Lead batteries are completely different from lithium, NiMH or NiCd batteries. Despite their high
capacity they can only provide low currents. The charging process is also different.
The charging current for modern lead batteries must not exceed 0.4C; 1/10C is perfect for lead
batteries.
A higher charging current is not permitted; it would overload the rechargeable battery!
This not only causes danger of explosion and fire, but also danger of injury from the
contained acid.
Also always observe the information printed on the battery or the information provided
by the battery manufacturer on the permitted charging current.
The charger must be in the main menu.
Select the rechargeable battery type "Pb BATT" with the
"INC" or "DEC" button here, see figure on the right.
Confirm the selection by pressing the "START/ENTER"
button.
Then use the button "INC" or "DEC" to select the different rechargeable battery programmes:
• "CHARGE": Charge rechargeable battery
• "DISCHARGE": Discharging the rechargeable battery

b) Charging Rechargeable Batteries ("CHARGE")

The charging current to be set depends on the battery capacity and is usually 0.1C (also see
chapter 7). High-quality lead batteries also can stand a charging current up to 0.4C. However,
you should always observe the battery manufacturer's instructions.
The value "0.1C" means that the charging current is equivalent to one-tenth of the
rechargeable battery's capacity. For a lead battery with a capacity of 5000 mAh (= 5
Ah) the charging current at 0.1C must be set to 0.5 A.
Proceed as follows to charge a lead battery:
• Fist, choose the rechargeable battery type "Pb BATT" with the buttons "INC" and "DEC" as
described in chapter 13. a) and push the button "START/ENTER".
