▼Notes
① This product is a 12 V lead acid battery dedicated desulfator.
② Be careful of reverse connection. It may damage the circuit board.
③ The board needs to be insulated. Avoid damage to the base material due to contact between the battery positive and negative.The 8801 8806 model is with reverse polarity protection.
④ After mounting, firmly fix the board plate.
⑤ The connected battery itself is the power source of the device, and if the battery capacity is too low (eg 4AH), it needs to be charged once a day, and 20AH or more must be charged once for 7 days.
Q & A:
1). What is a battery desulfator?
---High-frequency peak pulse delivers an electronically controlled pulse to the battery, causing crystalline sulfates to dissolve back into the electrolyte, and so restoring battery function.
Electrolyte strength regaining the battery ability to receive charging current and deliver discharge current.

2). What battery is it suitable for?
---12V lead acid battery, such as AGM, SLA, VLRA, etc.

3) What are the precautions during use?
---The desulfator should be installed as close as possible to the battery terminals. (within 14 inches, or 35 cm)
--- Not every battery can be saved, especially the almost dead battery.

4)How long does the desulfating process take?
---The process can take up to 3 weeks.

Note：successful in recovering all sulphated batteries it will not recover batteries with damaged or dried out cells. Check the battery voltage, the voltage should be greater than 11.5V, otherwise this battery desulfurizer can not enter the working cycle.
