Lead Acid Batteries
Can you Charge a lead acid battery with a regulated power supply?
I been using a radioshack regulated 3 amp 13.8 Vdc Power
supply to charge up 12 volt 3 Ah lead acid batteries Will charing them them with the power supply ruin the batteries? Will they explode or anything.
After leaving them on for a couple hours the current (millamps) drop down to about 4 millamps
Will leaving the batteries on the power supply do anything to the batteries.
I’m just worried about them exploding or something will this happen if charged like this
Charging lead-acid batteries with a power supply
Lead-acid batteries can be charged manually with a commercial power supply featuring voltage regulation and current limiting. Calculate the charge voltage according to the number of cells and desired voltage limit. Charging a 12-volt battery (6 cells) at a cell voltage limit of 2.40V, for example, would require a voltage setting of 14.40V.
The charge current for small lead-acid batteries should be set between 10% and 30% of the rated capacity (30% of a 2Ah battery would be 600mA). Larger batteries, such as those used in the automotive industry, are generally charged at lower current ratings. Cells constructed of a non-antimonial lead grid material allow higher charge currents but have a lower capacity. The cylindrical Cyclone is sealed and can sustain a pressure of up to 3.5 Bar (50 psi). A pressurized cell assists in the recombination of gases.
Observe the battery temperature, voltage and current during charge. Charge only at ambient temperatures and in a ventilated room. Once the battery is fully charged and the current has dropped to 3% of the rated current, the charge is completed. A good car battery will drop to about 40mA when fully charged; a bad battery may not fall below 100mA.
After full charge, remove the battery from the charger. If float charge is needed for operational readiness, lower the charge voltage to about 13.50V (2.25V/cell). Most chargers perform this function automatically. The float charge can be applied for an unlimited time.
