I have never seen a leaked silver oxide cell. No leaked lithium as well. But many leaked Alkaline and mercury cells.

Hello Andreas,

what do you mean with do not leak?
As long as those cells are kept in a cold and dry place without being used I heard of no leaking.
When they are in some electric equipment in use it may be similar but I'm not sure.

I haven't had any Silver Oxide battery leaked either. I do have a lot of alkaline batteries leaked.

Are the batteries still producing voltage?

I don't want to open the antique packaging to measure ...

As far as I see there is a hole in the rear cardboard packaging, an a hole in the front plastic packaging.
So you can pierce the pikes of the digital voltage meter through these holes.

There is no opening in the front of the blister pack, but I have attachments for my test leads with needle tips. These are used to perforate cable insulation in order to measure the conductor.

A not very expensive multimeter (new) came with two AA batteries from some manufacturer.

After a year I checked the batteries (I keep records because I'm afraid of battery leaks) and there was a small pool of electrolyte in the battery compartment.

I will never use any batteries other than Duracell again.

I will never store battery-operated equipment with batteries in them…

OK, I refer to less frequently used items. For things like TV remotes that I use all the time, I leave batteries in and check much more frequently than annually.

I'm paranoid because I see what forgotten batteries can do in photographic equipment

Completely understandable! While I agree with reliance on a known brand, it’s also important to acknowledge that factory defects can happen even within such a brand, and the chances of counterfeiting exists. So frequent checking is not necessarily an obsessive-compulsive behavior. Nipping a battery leakage in the bud is much better than the consequences of not doing so. As you well understand and state!

My batteries have to last a year, then I replace them unless they are used up before then. Duracell hasn't let me down yet, other branded batteries will be just as good, but I throw everything else away immediately.

My iPhone reminds me.

Branded batteries also expire. But in this case it took years ...

Minolta Hi-Matic GF: Corrosion fixed in the battery compartment, impressions from inside the camera

I already had this small Hi-Matic on the table last year. The previous owner had probably forgotten the two AA batteries in the battery compartment, which had leaked. The two batteries were so swollen that I could only pull them out of the compartment with force using combination pliers and a...

Canon T90 and T70: Rescuing victims of leaked battery electrolyte

From a collection of cameras, I chose these two T90s and one T70. They all have one thing in common: their battery compartments cannot be opened because the batteries have leaked. The battery acid has cemented the battery holders and the battery compartment cover of the T70. When I tried...

I have Duracell AA batteries leaked in my F4S and my Fluke 289 DMM. The leaked batteries were made in the USA. Duracell gave me coupons for new batteries since the leakage didn't cause any damage. My conclusion any brands alkaline batteries may leak and they don't have to be old or depleted. The leaked battery still have 1.4V and still deliver sufficient power. I since stopped using alkaline batteries. I use Li-Ion rechargeable AA for low drain devices and NiMH for high drain devices.

Metal contacts are corroded, the electrolyte spreads over the connecting cables and destroys conductor tracks on the circuit board, component connections corrode and the vapors can settle in unexpected places inside the device and cause corrosion.

At this late date, I'd regard those Sony batteries as collectables!

In recent years, I've had terrible luck with Duracell-brand alkaline batteries. But OTOH, a couple of years ago, I purchased a 1970s Panasonic radio containing what may have been the original batteries. One had leaked slightly, but not enough to cause damage, while the others looked good as new, though they were dead.

Battery acid and electrolyte damage in photographic devices

I have collected some photo equipment that needs repairing in order to develop/train my repair skills. So far, most of the problems have been where leaked battery acid and leaked electrolyte from electrolytic capacitors contaminated contacts, solder joints, wires and conductor tracks on circuit...

Nikon MD-12 Motor Drive renovated

A friend had asked me to look at his Nikon MD-12 Motor Drive. The Motor Drive for the Nikon FE(2) and FM(2) hasn't been available for a long time. A contact in the battery compartment was corroded but was poorly cleaned. I didn't say yes right away because I usually only work on my own stuff...
