Customer ServiceThe charger employs a transformer at the source end which refines the charging control for low voltage batteries. Normally, in bridgeless SEPIC topology, two High Frequency Transformers
Customer ServiceThe transformer shouldn''t be capable of outputting more than 14.4 volts after rectification. 14.4 is an acceptable voltage to charge a 12v lead acid battery. Effectively, the transformers output is in parallel with the battery terminals, which is around 12.5 volts.

Customer ServiceIn this article we investigate 4 simple yet powerful battery desulfator circuits, which can be used to effectively remove and prevent desulfation in lead acid batteries. The first method uses PWM pulses from a 555 PWM circuit, the second method implements an ordinary bridge rectifier for implementing a 100 Hz frequency based desulfation, the
Customer ServiceYou need about 14.4 V DC to fully charge a 12 V lead-acid battery. Please calculate your peak voltage minus your voltage drop across the rectifier and report back. Maybe. 12 x 1.414 ~= 16.8V. - bridge about 1.5V =~~ 15.3V. That gives about 1v headroom for "droop" and not peak rectification .
Customer ServiceTo turn it into a battery charger you need first to select a voltage range of about 14 volts. Maybe even 15 volts. Smart chargers are able to determine what the right charge voltage needs to be to prevent damaging the battery. If you turn that into a charger you''re going to need a lot more control circuitry.

Customer ServiceIn summary, the conversation discusses the process of charging a led-acid battery using a transformer to convert 220V AC to 12V AC and a bridge rectifier to convert it to DC. It is suggested to use a 12V 3 amp lamp in series with the battery to limit the charging current and prevent damage to the diodes.

The primary winding of the transformer is connected to the AC mains supply, while the secondary winding is connected to the charging circuit.
It is responsible for converting the alternating current (AC) input voltage into a direct current (DC) output voltage. The rectifier ensures that the battery is charged properly and efficiently. The most commonly used rectifier in lead acid battery chargers is a diode rectifier.
Sulphation in lead acid batteries is quite common and a big problem because the process completely hampers the efficiency of the battery. Charging a lead acid battery through PWM method is said to initiate desulfation, helping recover battery efficiency to some levels.
A lead acid battery consists of several cells, each containing lead plates immersed in a sulfuric acid electrolyte. The cells are connected in series to achieve the desired voltage. The battery can store and release electrical energy through a chemical reaction that occurs between the lead and sulfuric acid.
A suitably rated transformer, a bridge rectifier and an ammeter are all that's needed for the purpose. The transformer voltage must be rated approximately 25% more than the battery voltage rating, that is for a 12V battery a 15 to 16V supply may be used across the battery terminals.
Charging a lead acid battery through PWM method is said to initiate desulfation, helping recover battery efficiency to some levels. Sulphation is a process where the sulfuric acid present inside lead acid batteries react with the plates overtime to form layers of white powder like substance over the plates.
