How many of you have experienced batteries that eventually leak or corrode while inserted in your various consumer devices? When this happens it may even ruin the device itself!

How important are some of your electronic devices? While no one wants to experience battery leak damage to any of their gadgets, some of those gadgets may be more important than others – especially when considering “mission critical” devices.

You might consider using batteries that are specified not to leak or corrode.

Here’s what I discovered:

First of all, you might be interested to read the following article:

“Battery Corrosion, Why They Leak And How To Prevent It”

It reviews why battery corrosion happens, how to prevent it, and how to clean it up.

To summarize, the white fluff that fills in around battery compartment terminals is from leaking alkaline batteries. Alkaline batteries may leak from a “parasitic drain” which slowly discharge batteries (more info in the article).

To clean up leaking alkaline batteries and the white fluff on battery terminals, use vinegar or lemon juice. I’ve used a cotton swab soaked with this solution. Sometimes however the terminals may be so corroded that you just can’t fix it…

In comes the latest Energizer battery…

Energizer claims a “No Leaks Guarantee” and I just wanted to put it out there for your information and benefit. I will be purchasing these batteries in the future.

“Even as battery technology has evolved, battery leaks are still a problem today. Many brands of batteries can still corrode and damage devices after being fully used. Energizer batteries are different. Our batteries are designed to prevent damaging leaks or we will replace your device.”

That’s quite a statement.

On their website they state that they will repair or replace, any device damaged by leakage from Energizer MAX® Alkaline batteries either during the life of the battery or within two years following the full use of the battery. If exact replacement is not available, devices may be replaced with a product of comparable market value at the time of claim.

Energizer batteries guaranteed not to leak include Energizer MAX®, Energizer Recharge® Power Plus, Energizer® hearing aid batteries, and Energizer® Ultimate Lithium™.

Note: The ‘AA’ size is the most common consumer battery in the world.

And for your further information, they say Energizer® Ultimate Lithium™ Batteries are GUARANTEED NOT TO LEAK. Due to advanced technology, Ultimate lithium™ batteries will not leak under normal consumer usage.

Energizer Ultimate Lithium AA Batteries

I use lithium batteries in all of my mission critical devices. Also, lithium batteries are MUCH, MUCH BETTER when it comes to cold weather tolerance. They perform better.

Okay, I know that I have written lots of articles over the years about batteries. However I figured that I would throw out this latest information.

I still use my “eneloop” rechargeable batteries for some things, and they continue to perform well. I consider them to be a good long-term prep item (along with solar charging capability). I wrote about them in the following article: Best AA Rechargeable Battery
