Kivner200AH Lead Acid Battery Desulfator 12-48V Auto Pulse Desulfator 2A Battery Regenerator Extending Battery Life
Main highlights- [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
- [Effect] 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
- [Easy to use]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
- [Compatible Batteries] 12V~48V, Max 200AH lead-acid battery,such as AGM, SLA and VLRA
- This product uses the 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

BeyprernBattery Desulfator, Automatic Pulse Battery Reconditioner Extend Battery Life for Lead-Acid Batteries (12V-48v Green 200AH Large Clips)
Main highlights- Restore and extended battery life :Usually, batteries that have been used for more than six months need to be repaired to extend their lifespan. An advanced battery repair mode uses slow pulse reconditioner technology to detect battery sulfation and acid stratification to restore lost battery performance for stronger engine starts and extended battery life.
- Note: This battery desulfator is for sulfated batteries, not dead ones, Battery scrapping can not be repaired, won't solve all battery problems, but it does desulfate them. This product is ineffective for batteries with damaged plates, dried up electrolyte and severe lack of electrolyte. The battery needs to be able to be charged when using our desulfator device.
- Widely used;Intelligent automatic repair power without damaging the battery. Lead acid AGM/GEL/EFB, MF, Flooded battery, VRLA, SLA, wet battery. For cars, trucks, motorcycles, SUVs, golf carts, farm vehicles, motorboats.
- New advanced technology: High-frequency peak pulse delivers an electronically controlled pulse to the battery, dissolves sulphates without damaging battery plates.
- Desulfating process: The process can take up to 1-3 weeks. It needs to be left on the battery for more than 15 days to have the effect of repairing the battery .Not every battery can be saved, especially the almost dead battery.
