Daily charging
·The storage battery that has been made first charging and used in normal condition, then
charged again, it is named daily charging.
·Its way is almost same as the first charging.
·The recharging volume is 1.2 times than the last electric discharging. But the new storage
battery’s former five times’ charging volume should be 1.5 times than the last electric discharging.
·During any charge, the temperature of electrode should not exceed 45℃, otherwise it should be
taken measures such as reducing artificially charging current or lowing the temperature. If the
temperature still does not drop, you should stop charging till the temperature drops down.
Adopt intelligent charging to do daily charge, the former five times of new battery should do
equalizing charging according to operation instructions of intelligent charger.
Equalizing charging
·During using of the storage battery, it often occurs to disequilibrium among the voltage,
density and capacity.
·Compared to most of the batteries, several storage batteries’ proportion of voltage and electrolyte
rises slowly during the course of charge and discharge, its storage battery’s proportion of voltage
and electrolyte declines faster than most of other batteries.
·Make equalizing charging in the following case:
a. discharge voltage often drop down final voltage;
b. discharge current is often larger;
c. not charge in time after discharge;
d. the electrolyte is mixed with impurity with a little harm;
e. It often be charged deficient or has not been used for a long time;
f. Check or clean sediment after taking out the storage battery group
The way of equalizing charging:
(PCA Automatic Charger Operation Instruction)
① Firstly, charge the storage battery normally, and then rest for 1 hour after the end of charge.
② Charge it again with the second phase current of normally charge until the electrolyte gives
off a large number of bubbles, and then stop charging for 1 hour.
③ Do it several times as mentioned above until the voltage and the density keep invariable and
the storage battery gives off a large number of bubbles immediately when charge again.
Additional charge
·If one day’s work cannot be fulfilled in one charge, carry out additional charge during breaks.
·When the temperature of circumstance is low, carry out additional charge.
Charge for long-term storage
·Carry out equalizing charging before storing.
·Carry out equalizing charging once every 15 to 30 days during the storage period.
