Types of Batteries That Can Be Reconditioned
1. Lithium-Ion Batteries
These batteries are rechargeable and becoming more popular, yet they are more expensive than the traditional battery types. There are several ways to recondition a lithium-ion battery, including fully discharging it and placing it on the charger or placing the discharged battery in the freezer for 24 hours and then recharging it.
2. NiCad Rechargeable Batteries
Nickel-based batteries suffer from performance issues, primarily when recharged before they are completely dead. To restore the performance, reconditioning is needed, which requires putting high voltage on the battery terminals.
3. NiMH Rechargeable Batteries
The Nickel Metal Hydride is another rechargeable battery that is better than the NiCad. To recondition a NiMH rechargeable battery, you need to run deep charge cycles to regain the performance.
4. Lead Acid Car Batteries
These wet cell batteries don’t require a lot of effort to recondition. You can top off all of the cells with distilled water. Then, it helps to apply a slow charge to the battery.
5. AGM and Gel Type Batteries
These batteries are safer than the lead-acid variety because nothing spills out if the casing cracks. The best way to recondition the gel battery is to completely discharge it and then recharge it slowly.
