Lead Acid Battery Sulfate Remover 80A Desulfator

The lead battery activator prevents the formation of crystalline sulphate deposits on lead plates. Crystalline sulphate deposits form especially in lead batteries that have been stored for a long time, used rarely or discharged with low current. The life of the battery can be significantly extended by the desulphator device.

A different design compared to the previously shared Advanced Battery Desulfurizer Desulfurizer Circuit and other Desulfurizer circuit projects. Especially the long pulse interval, low current draw, can be suitable for long-term maintenance, and the circuit does not use a coil. The circuit is based on CD4060, CD4040 cmos integrated circuits, a bit complicated, the PCB drawing is made according to SMD components to keep the size small.

Lead-acid batteries are designed to reach a service life of 8-10 years with proper maintenance. However, things are different in practice. The service life is much lower than possible, especially in seasonally used lead batteries, sulfation starts more quickly.

Sulfate formation is a basic effect of lead batteries, crystal sulfates start to cover the lead plates during slow discharge or self-discharge when not in use. The stronger the coating, the less energy can be stored and given. Sulfate deposits are the main cause of premature failure of lead-acid batteries. Sulfate formation increases significantly at higher ambient temperatures.

Sulfate Remover Battery Desulfator

The device does not require an external power source. It prevents sulfate accumulation on lead plates with periodic peak current pulses of approximately 60A-80A. Existing sulfate deposits are also dissolved and mixed into the battery fluid as active sulfur molecules.

Despite the high current pulses of approximately 60A-80A, relatively little energy is drawn from the battery since the pulse duration occurs approximately every 27 seconds.

The pulse duration is 100μs. The arithmetic average of the current consumption of the circuit, including discharge current pulses, is only 5-6mA. There is no need to disconnect the device while charging the battery.

With a current consumption of 5mA, it corresponds to approximately 4Ah per month. There is a built-in protection circuit that automatically disables the device when the battery voltage is 10V. In this way, it prevents the battery from being completely.

Technical data:

Discharge pulse current: 60-80A
Pulse duration: 100µs
Pulse interval: approx. 25 seconds
Current consumption: approx. 5-6mA (as arithmetic mean)
Operating voltage: 11-16V

In addition, there is a version of the battery desulfator combined with the LM317 battery charging circuit.
