Default Re: Has anyone had issues with Rayovac Alkaline batteries leaking

I have to decide what I going to do with the Rayovac batteries that I have that are prone to leaking I would like to get some use out of them anyone have any ideas

in the old days, batteries were inside a cardboard sleeve that went into the battery holder - i wonder if it was to catch leaks?

well zinc carbon batteries leak a liquid and not a vapor so card would soak it up.

Default Re: Has anyone had issues with Rayovac Alkaline batteries leaking

I am going to answer this question once and for all about the variances between lot number of one expiration date and the lot number of a different expiration date and see how much difference in amp hours there is because I want to know if there is anything to this crap or there might be something to this but if this is the case I really would not have any confidence in there product at all and it will be because of quality issues ( weather this because of different quality of metal used different quality of electrolyte it does not matter what the issue is it still a quality issue now if is because of EPA regulations of different ingredients that can not be used anymore this is hole another issue that they do not have control over but if you can not make product that does not leak any more stop selling the product until you find a solution for the issue ) with there products and that these companies do not care about what product they are selling anymore

One note about the leaking issue with this type of battery why not put a CID on Alkaline battery if internal pressure builds up and it has to release the excess pressure and make the battery inoperable I would be all for it if it would stop them from leaking all over the place or use a thicker metal and seal material what ever you need to do to make it less likely to leak yea I know it would make the cost of them to be more ok so be it if you want to stop having clams against your products

or put a disclaimer on your product that says the following that these might leak just sitting in storage or if expiration date has passed or if use different expiration date in a device or if you use new and old batteries in a device which is already there—> this would be a much to do by the customer take a volt meter and check the battery voltage of each and every cell and do not use them if the voltage difference of 0.20 volts yea I know I am asking the customer to do to much to use this product

I will post the results of the testing results maybe today or sometime this week

Alkaline batteries internally make hydrogen gas when they're discharging due to use or storage, or see reverse polarity (imbalanced string). They need to burp.
Problem is that also spits out caustic electrolyte, which then wicks/creeps along things due to the tiny current leakage of the wet film. The common narrative is all of this was not a problem with old battery's added mercury- which stopped the offgassing. But that ban started in 1996! so say 20 years ago. Rayovac went bankrupt in 2009, $4.4B in debt then Spectrum Brands like another P&G mega-corp has them. So they are just an acquired brand name.

What's weird today is many alkaline batteries leak badly, but others do not.
Something nose-dived in the race to the bottom for price. It's like a casino in Vegas. Duracell are the worst- even their "made in USA" ones piss just as well as ones made in Indonesia etc. regardless of lot # or expiry date.

So that looks like a quality problem has come in. I took one apart and the seal is a polypropylene piston with some bitumen, for Duracell or Energizer. Either the seal is crap or the battery's chemistry makes too much gas, or both.
Too bad they continue to "blame the customer" instead of fixing their crappy product, and make guarantee claims impossibly difficult.

Note the government definition of "Made in USA" changed, I expect wording on batteries to get cleaned up. Hear that Duracell and Mr. Buffett?

This says a lot and some more reasons WHY I am NOT going to buy anymore of this type of battery until all of them get there shit together

Price out using Energizer ultimate lithium cells, at first they look more expensive but they have longer life. And start out a bit higher voltage 1.8V but say almost 2x price yet 3x capacity.
I found 9V L522 at Home Depot and going to use in my multimeters.
For AA, AAA : rechargeable Eneloops or Ikea Ladda are what I use now.

The voltage of 1.8 is going to be a problem for digital devices in general the question I have is why does the voltage need to be that high

It is not that high, it is just the open circuit voltage.
I.e. with an actual load it comes down a bit, check the datasheets.

The cell voltage is based on the chemicals used in the battery. Lithium has a high potential, you'll usually see 3.7-4V and here Energizer did get it down using iron-disulfide.

I mentioned the 1.8V just to check the device can take it, it's the worst case and only for a short time. I think it would be worse for two battery devices seeing 3.6V as many IC's are rated ~3.6V max. before the higher classes.
Fluke does not mind it, the voltage regulators drop it down.
The 9V L522 is ~8.4V nominal and 9V peak.

Energizer ultimate lithium are guaranteed to not leak at all: Energizer battery leakage policy
But again, you have to ship the device to them which is gross.
