Battery sulfation low current repair
Luckily, sulfation can be reversed and prevented. The lead sulfate that has hardened and crystallized, which can't be removed by charging, can be removed by another process, called desulfation. This is the most important aspect of battery reconditioning. Applying a very high voltage to the battery plates. As we mentioned earlier, discharging a battery means sulfation will develop. Fact. There's nothing you can do about it. The more discharge, the more lead sulfate develops on the battery. Sulfation is not the only issue that can afflict batteries. There is also acid stratification, which can also be called acid layering. A well-rounded and full battery reconditioning process will. Around 50% of all breakdowns are due to battery failure.
