What is Battery Reconditioning on Charger? Guide & Steps


Make sure you follow the instructions carefully to avoid damaging the battery. There are many different types of batteries, and not all of them can be reconditioned. This is a difficult question to answer because it depends on a lot of factors.

The microprocessor regulates the current and voltage supply to the battery and ensures to charge the battery optimally. These chargers are helpful you can try these out to bring a dead battery back to life. But battery reconditioning chargers don’t overcharge the battery and recondition dead batteries.

This unit also has a mechanism to readily check its alternator and protection against wrong polarity connection. After slow amperage, the charger delivers 100% of the current to the battery but does not fully capacitate it yet. The max amperage lasts as long as the battery reaches a capacity of around 75-80%. The reconditioning charger works by removing these sulfur crystals and, in the process, reviving both the integrity of the electrolyte and the cells’ electrodes. Additionally, A battery can be reconditioned to have up to 70% of the power of a brand new battery.

Repeated overcharging naturally reduces the lifespan of a battery because all batteries have limited charge-discharge cycles. Upon reaching full (100%) charge, indicated by around 12.8 volts, the smart charger switches to float charging. The charger maintains a steady amperage as long as the voltage does not reach full (100%) capacity. Stages 4 and 5 are iterative (forming a loop) until the battery is fully charged. After desulfation, the charger applies only around half (~50%) of the maximum current to get the battery ready before charging it properly.


It will charge the battery until it reaches approximately 80% capacity. This is the stage when the charger tests the battery by sending a higher amount of current. Once the charger finishes dissolving the sulfate, it charges the battery article source by delivering a 50% current. You should know the features of a battery reconditioning charger before you buy one. It analyzes the battery’s health while charging it and decides whether it requires normal charging or reconditioning.

You can also have a pulse charger which produces frequency between 40Hz to 200Hz. The battery reconditioning charger must be able to properly read and calculate the voltage and amperage of the battery. This will allow it to monitor and adjust its current and voltage input to the battery itself.

Here are the steps that a battery reconditioning charger follows to charge a battery. The actual meaning of battery reconditioning is getting back the health of the battery. After getting reconditioned, the battery will be able to get the full charge with the help of the charger. Here are a few questions usually asked by see post most people regarding charger reconditioning modes. Doing this will gradually restore the battery’s ability to hold a charge, and eventually it will be as good as new. Of course, you won’t be able to get the battery back to its original capacity if it’s been damaged – but you can usually get it back to around 80% or so.
