Assembled 12V Lead Acid Battery Maintainer & Desulfator Kit with Reverse Polarity Protection

The input voltage for this product is 12Vdc, with a peak voltage of 20V (pk-pk) and a rated current of 35mA. The power consumption is 0.2w, and the frequency range is 1.50 KHz.

To use the device, you can connect it to the battery whether the battery is charged or not. Connect the red wire to the positive pole of the battery and the black wire to the negative pole.

This product is a 12 V lead acid battery dedicated desulfator. Be careful of reverse connection, as it may damage the circuit board. The board needs to be insulated, and after mounting, it should be firmly fixed to avoid damage to the base material due to contact between the battery positive and negative.

The connected battery itself is the power source of the device, and if the battery capacity is too low (e.g., 4AH), it needs to be charged once a day. Batteries with a capacity of 20AH or more must be charged once every 7 days.

A battery desulfator is a device that uses high-frequency peak pulses to deliver an electronically controlled pulse to the battery, causing crystalline sulfates to dissolve back into the electrolyte and restoring battery function and electrolyte strength, regaining the battery's ability to receive charging current and deliver discharge current.

The desulfator is suitable for 12V lead acid batteries, such as AGM, SLA, and VLRA. The desulfator should be installed as close as possible to the battery terminals, within 14 inches or 35 cm. However, not every battery can be saved, especially the almost dead battery.

The desulfating process can take up to 3 weeks. The desulfator is a smart battery life extender that prevents sulfate build-up. If the item works with a light on and a little buzzing, it is in good condition.

It is important to note that there is no polarity reverse protection, so please double-check the positive and negative sides before connecting the device.
