Duracell again, unfortunately!

**Saltfever** · Aug 25, 2018, 07:29 PM

Another electronic device ruined! I had been using this until about 2015 then into storage during a shop rebuild and just found it this week. I have no idea how long ago this went bad. Every Duracell battery I have had in the last 5 years has corroded and ruined an electronic device! Please be warned.

After losing several expensive flashlights and some other electronic gear to leaking Duracells, I swore off them entirely and bought Energizer (the pink, marching bunny) batteries.

Since using them for about two years, I haven't had a single leaker. I eventually used up the remaining Duracells in applications where, if they leaked, they couldn't harm anything and the contacts were easily accessible for restoration with a Dremel.

Buy some Energizers and try them. It's a cheap experiment and I think you'll be pleased.

Energizer even guarantees no leaks...

We owe it to our friends and the technical community to get the word out. The warrantee is limited to replacement of a 98 cent battery regardless of the value of the instrument it has ruined! I lost a $1,200 device due to Duracell corrosion.

My computer calendar is programmed to remind me to inspect the batteries in every valuable battery-powered device on a regular basis. For equipment that expensive you should be doing something similar.

Anything of value is now stored with no battery inside. They are inserted at use. The initial, expensive, loss was a stored device before the Duracell debacle was known. Low value stuff (clocks, flashlights, etc.) are now changed every year at spring daylight time. I don't check charge . . . just toss them out. Your calendar idea is a great suggestion in lieu of alternate methods.

I've had both Duracell and Energizers leak, current recovery job is a Mitylite split by Energizers, the mini-maglite was totalled, as was a 6D no-name by Duracell 'industrial' cells within the marked use by date.

Now using GP Ultra's as I've had NONE fail even after the use by date.

I have some pretty expensive laser surveying and construction leveling equipment that I hardly ever use. I have made up tags and attached them to the carrying or storage cases with the size and number of batteries required then removed all of the batteries when or if ever I need to use them I will install fresh batteries then toss them when finished or use them in other things I don't leave batteries in anything any more unless it is a near daily use item and yes I no longer use duracell

I could be wrong, but I am beginning to form the opinion that the only safe way to guard against battery leakage is to never leave any brand in in anything that you don't use frequently

Exactly! And with the ubiquitous use of electronics in measuring instruments, a financial loss to corrosion is certain. I find the convenience of instant zero, or the ease of absolute vs incremental movement is trivial compared to the risk of corrosion. I am gradually phasing into mechanical everything and don't consider it a step backwards at all. My mechanical height gauge can be set to zero anywhere I want.

This is certainly true of Alkaline AA & AAA batteries. I’m not so certain of other batteries and would love clarification if some types leak more often than others. I’ve never have had a coin cell leak for example. Apparently the iron phosphate Lithium don’t leak either.

For me the more functions the better! However the reason I’m very inclined to buy digital these days is that they are easier on old eyes. Honestly I never thought I would say that but I use to wonder why the old machinist use to run around with magnifiers clipped to their glasses. Sadly 35 years later I know why!

I figure my mechanical goodies will be usable after the next nuclear war. Otherwise I will enjoy digital for as long as I can. I just need to be careful about what I buy battery wise.
