I had a really odd situation earlier with some zink size 10 batteries that I’m hoping someone can explain.
I’ve only just started using the Virto Infinio Titanium HA’s. I’ll do a review in a couple of weeks time. They take size 10 batteries.
Not wanting to be caught short and also not wanting my son to swallow them, I took 8 out of a pack and put them securely inside a little metal container I have attached to my keyring. As far as I know the container is made of steel. the outside is shiny the inside is slightly mat texture so I’m not sure how finished the inside actually is. It’s incredibly secure but also a lovely thing just to hold. I’ll put an amazon link if I can find it.
Anyway, out shopping today, batteries dies. Ah ha I thought I planned for this. I took battery after battery out, all dead. All 8 of them. utter and complete madness.
Before anyone asks, No, I did not take the stickers pull tab things off the batteries before putting them in the container. I took one out, I took the sticker off it, shoved it in the HA, nothing. all gone.
I know these batteries behave a bit weirdly, is it possible the container could somehow have drained them, or did I just get a really weird dead pack of batteries?
If the container might be the issue, can anyone recommend something like it/ a really nice stirdy tiny container that fits on a key ring, could hold 2 CIC hearing aids and or some tiny batteries, secure so that a kid couldn’t break into it?
If the batteries were being shorted by the metal case you would know it immediately. It would have become extremely hot. You should never store batteries in a metal container to prevent the possibility of fire, especially in luggage when traveling. But, yes, get a plastic one to be safe. No idea why the batteries were dead unless they were very old or the seals somehow gave out.
An earlier post a few months ago had a link to the test where the batteries were allowed to touch and they discharged even with the air tabs in place.
So don’t let the batteries touch!
You can use one of the those daily pill containers and place one and only one in each storage slot so that none of the batteries touch.
If they come in one of those child resistant packages, just leave them in the pie shaped wedge when cutting with a pair of scissors so that the batteries can’t touch.
They also make cheap hearing aid battery carriers, but most of them are for the smaller 312 battery.
this is made for pills not batteries, I use a flat micro-card plastic container with a foam pad on the bottom, holds up to 12 #13 bats without moving around, done so for the past 20 years, never had any issues.
1] The tabs on the batteries, do NOT prevent them from being shorted out by other batteries, also with their tabs on.
2] You CANNOT house the batteries - even just a single one - inside or along with anything metal. It WILL short the batteries out.
3] You MAY NOT feel heat from a shorting battery IF the body of the metal container, is sufficiently large enough in relation to the tiny battery, to act as a heat sync.
Or you do not check the temperature quickly enough… meaning that the short could happen when the batteries just chance to make contact, and as you bump or tip the case, and once that happens to puny cell discharges before you come by to check the case again.
