Kivner10% Off400AH Lead-Acid Battery Desulfator Battery Maintainer Auto-Setting for 12V-48V Auto Pulse Battery Revive Battery Regenerator
Main highlights- You will feel the battery performance improvement after 2-3 weeks of use. It depends on the usage of the battery and the amount of lead sulfate crystals, the more lead sulfate crystals accumulate, the longer it will take...Before using this product, please test the battery voltage first. When the battery voltage is less than 11.5V, please charge the battery first. When the battery voltage is greater than 11.5, use the battery desulfator
- The main reason for the deterioration of lead-acid battery:When lead-acid battery is repeatedly charged and discharged for a long period of time, the sulfuric acid in the electrolyte and the lead in the electrode will undergo a chemical reaction and turn into lead sulfate crystals (sulfation), which is the main reason for the deterioration of the battery and the charging failure
- Our Battery Desulfator Battery Maintainer adopt high-frequency peak pulse to prevent lead sulfate crystals from sticking to the electrode, and gradually decomposes and removes the lead sulfate, extending the life of the battery and keeping the electrode in a near-new state
- Connect the red to the positive (+) terminal of the battery and the black to the negative (-) terminal of the battery. Once connected, the battery voltage will be recognized automatically without manual setting.If the device is not working, check whether the voltage is too low. Please try again after charging
