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.Quote:

Your calendar idea is a great suggestion in lieu of alternate methods.
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'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.Quote:

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.Quote:

Still ended up with damaged hardware, some more valuable than others.
The problem is so many devices switched over to AA or AAA that you have a hard time finding hardware that doesn’t use these batteries. DVM’s for example use to use 9 volt transistor batteries. The current one is AA. Even the house thermostat uses AA.
I’ve heard it said that the AA lithium batteries don’t leak but haven’t been able to verify this. If anybody has some info I’d love to hear it. Also has anyone ever seen a “coin” cell leak? I have a number of devices using these coin cells and so far no leaks.
I guess a leak isn’t as bad as a lithium polymer battery catching on fire.
For flash lights I’m switching over to the Milwaukee system and their rechargeable 12 VDC batteries. They work with the tools and replace just about everything but penlights. Somewhat expensive but also more usable in my estimation. Basically one truck light and one for the house. They actually might be cheaper considering how many flashlights I’ve purchased over the years. Some corroded to hell in a year or two.
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.Quote:

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.Quote:

Grandfather would put a small piece of rigid paper between the battery terminal and contact point in the device, usually a glovebox flashlight. He'd then attach a masking tape label to the case of the device with "paper" scrawled upon it. I found out about this trick because I finally asked Mom "what is wrong with Grandpa, he is labelling all kinds of things that clearly aren't paper as paper".
Yes, though with careful cleaning we managed to recover the digital micrometer it'd leaked in.Quote:
