DIY Battery Recondition Tips.
Battery Reconditioning Guide

With a DIY battery recondition you can save heaps! Why replace your tired battery when you can fix and reuse it? Imagine how much money that could keep in your pocket.

A dead battery is not only expensive, but inconvenient. And while knowing how to restore a dead battery may not solve the inconvenience, it can definitely eliminate the expense of buying a new one.

Plus, if you're so inclined, you can turn this skill into a very profitable business.

And the best part is that it's very easy and inexpensive.

You can successfully recondition any type of battery. Here’s a few general pointers to get you started.

Is Reconditioning the Same as Recharging Your Battery?

No, reconditioning is very different from recharging.

Importantly, in contrast to recharging a battery - which will restore its charge for just a limited time - when you recondition it, you can restore it to its full capacity.

What Types of Batteries Can You Successfully Recondition Yourself?

All types of batteries can be successfully reconditioned, from deep cycle/gel types to the usual 12V car battery. Even the newest car batteries available can be restored via standard lead acid battery reconditioning techniques.

It is worth investing a little time to better understand the various battery types out there and how they are best handled to improve battery life to give you valuable background info before you take the next step of reconditioning.


To reap the amazing benefits of DIY reconditioning, you must be aware of and follow basic safety considerations. For example, the recondition processing of lead acid batteries involves messing with dangerous acids which must be handled responsibly.

The Reconditioning Method

Most of the steps involved in battery restoration are common techniques readily integrated into your normal routine.

Taking the trouble to learn them will not only save you heaps of money otherwise spent on new batteries, but also help to protect the environment from the hazardous waste that old batteries contribute to.

The reaction of lead plates immersed in sulfuric acid generates electricity in automotive lead-acid batteries. However, this sulfate reaction also produces, along with electricity, lead sulfate.

When a healthy battery is recharged, this lead sulfate is converted back to lead and sulfuric acid.

But in tired battery, the lead sulfate changes to a crystalline form that coats the battery’s lead plates reducing its capacity. This process is known as sulfation. It is a common occurrence in lead-acid batteries and a major reason for their failure.

The good news is that you can often reverse sulfation utilizing a specialized high-current, pulse that effectively breaks down the crystalline lead sulfate and turns it back into lead and sulfuric acid, thus cleaning the lead plates and restoring charge capacity.

So before you throw that battery away, consider battery reconditioning as a way to save it.

And you can even earn a substantial amount of money by reconditioning dead batteries you get for free, and then reselling them.

A small investment for a large return!
