Kivner Battery Regeneration Extension Device Desulfator Water-Resistant Specification, Sulfate Removal, Lead Battery Recovery, Pulser, 12V Lead Battery Compatible KVN-BTF12 【Main Causes of Lead-Acid Battery Deterioration】Lead-acid batteries deteriorate and have charging problems because the sulfuric acid in the electrolyte and the lead in the electrodes react chemically over repeated charging and discharging, forming lead sulfate crystals (sulfation). 【Extending the Life and Recovery of Deteriorated Batteries】This product uses weak electrical pulses to prevent lead sulfate crystals from adhering to the electrodes, gradually breaking down and removing existing lead sulfate, extending the life of deteriorated batteries, and keeping the electrodes in a near-new condition. 【Effect】Effects usually appear after 2-3 weeks of use. The time required depends on the battery's usage and the amount of lead sulfate crystals, but it takes longer when there is a large accumulation of lead sulfate crystals. 【Installation Method】Connect the positive (red) terminal and the negative (black) terminal to the positive and negative terminals of the battery, respectively, and operation starts after the operation lamp lights up. If the device does not operate, check if the voltage is too low. Try again after charging. 【Compatible Batteries】12V lead-acid batteries. Warranty period: 1 year from the date of purchase. 【Product Description】 ●【Water-Resistant Specification】Can be used with peace of mind even if exposed to sudden rain or splashes. ●【Reverse Connection Protection】Even if the positive and negative terminals are accidentally connected in reverse, there is no need to worry about damaging the electrodes. ●Can be connected to the battery regardless of whether the battery is charging or not.
