Has anyone had issues with Rayovac Alkaline batteries leaking

Re: Has anyone had issues with Rayovac Alkaline batteries leaking

I had a red HFT alkaline PP3 that actually *exploded* leaving bits of the cell nearby...

Speaking of batteries, I have a bench DMM that uses 6xC (UM2) batteries, I wonder what's the best retrofit... Think I could probably do 2xLi-ion and no converter needed, just need to figure out how to charge from the AC adapter...

Re: Has anyone had issues with Rayovac Alkaline batteries leaking

I like others have had more duracell leakers then any other brand, also a couple of kirkland and enegizers. I bought lots of harbor frieght alkalines the orange ones and they expired in 2020 and still no leaks and powering devices, also tried harbor frights blue alkalines to good results and rechargeable units. However I did buy some eneloops and they are the best by far.

Re: Has anyone had issues with Rayovac Alkaline batteries leaking

Ive been seeing a lot of leaky duracell's lately. I was given some TV's and a box full of remotes... quite a few leaky duracells...

Heck, the first one that opened here was right next to a Wallmart. Just imagine the nerve to do that.

While we are on the subject of off topic: look at this picture, setting up a sign infront of the other stores sign.
Yea I can imagine that not ending well if they start trying to once over each other lol!
On the topic: Biltema branded batteries that I've used in the past have fared ok.

Had a bunch of leaking Duracells a couple of years ago, but not recently, touch wood.

Yeah the AA 14500 NiZn's I had were only like 900mAh. Total crap. They need to be in SMPS buck/boost with BMS. At 1.5Wh it's not way too bad though 2.4Wh NiMH is typical...

The charger ("official") I had could individually charge. So charging isn't the problem...

Re: Has anyone had issues with Rayovac Alkaline batteries leaking

it's my understanding that nizn are only a few hundred mA, and you dont charge them in packs anyway - atleast not with any retail charger

Re: Has anyone had issues with Rayovac Alkaline batteries leaking

Now that BMS boards are standard practice for Li-ion, why not have BMS for NiZn...

[stj]

Re: Has anyone had issues with Rayovac Alkaline batteries leaking

that would be a textbook case for 18650's and a boost convertor

Re: Has anyone had issues with Rayovac Alkaline batteries leaking

That may be fatal for something that does take 10 batteries. Lol

Re: Has anyone had issues with Rayovac Alkaline batteries leaking

I tried a couple and they are fragile. Powergenix NiZn were terrible in cycle life, I don't think I even got 10 cycles before they dropped dead, even with their own charger.

so if you pair them with NiMH you get 3v?

Yeah, maybe 5 with doing this...

Re: Has anyone had issues with Rayovac Alkaline batteries leaking

Yes they are at the 1.7 to 1.8 when new and as they age the voltage becomes lower when they reach about 1.5 volts they are pretty worn out and will not last long on a charge

Re: Has anyone had issues with Rayovac Alkaline batteries leaking

those batteries, big clive did a teardown of the Jugee branded ones - very interesting products!

there are also NiZN batteries - i think thats the chemicals anyway - they run at 1.5v but not many chargers support them.

I thought these NiZN batteries are like 1.7 or even 1.8V?

Re: Has anyone had issues with Rayovac Alkaline batteries leaking

Theoretically they are identical.
Question is if they are better because they probably aren't counterfeit!

Re: Has anyone had issues with Rayovac Alkaline batteries leaking

procell were marketed in europe for company use to deter theft by workers.
i doubt they are different internally.

Re: Has anyone had issues with Rayovac Alkaline batteries leaking

Anyone had experience with Duracell's Procell (all black duracell instead of copper top), are these any better?

I have a feeling that a lot of the non blister pack Duracell could be fakes. Not sure, for those people living in the USA there's a store "Big Lots" that I have a suspicion that they sell fake or self-packaged Duracells to get a better price (which isn't that much better)... I haven't seen any leaking on the shelf but these seem to all be in that paperboard under container and shrink wrapped on top. Not sure if these are fake or not but very strange packaging IMHO.

IMHO those carbon zinc batteries, they tend to "leak" into the air (as in they dry up instead of leaking liquid into your $EXPENSIVE$EQUIPMENT)... little/no equipment damage, but does damage the pocket book if you don't watch how much you pay. Plus their ESR is pitiful.

Re: Has anyone had issues with Rayovac Alkaline batteries leaking

For this reason, I have started to avoid alkaline batteries whenever possible.
For smoke detectors, remote controllers, and other applications with low drain, I've rediscovered / switched back to the good old Carbon Zinc ("Heavy Duty" / "Super Heavy Duty") chemistry. And from those, Panasonic and Toshiba are still the best, IMO - no leaks, and they will last for years and years without issue. On that note, the original C-Zn Panasonic batteries that came with my parents' DVD/home theater system are close to 15 years old now! Not only have they not leaked, but they are still holding up and used in the remote for that DVD player. (And yes, that DVD/home theater does see a lot of use, because it's used every time the TV is On.)

I still have some old Walgreens "heavy duty" batteries that are close to 10 years old.

Duraleaks (AAA "Optimum")

Those are the ones I mentioned that came in a cardboard box that hid the leaks. I don't remember all of the battery names.

9V ones for the smoke detectors inside the house (whose old batteries I transfer to use in my cheap multimeters afterwards.)

I do that too, except I have a huge pile now.

Re: Has anyone had issues with Rayovac Alkaline batteries leaking

there is a huge europe-wide chain called "Lidl"
do you have them in the u.s.??

Yeah, they just recently started popping up on the East Coast here... or at least where I am. In fact, one just opened this summer only a few miles away from me. So thanks for the tip, I'll check out their alkaline batts if I need any (probably some 9V soon for a few smoke detectors - there is always at least one that starts beeping on me right around fall-winter time when the temperatures start dropping.)

Otherwise... I've been to Lidl before. They aren't great when it comes to fresh fruit and vegetables, but there are other stores for that stuff. On the other hand, Lidl does have some items (snacks, meat, baking stuff, and condiments) that no other store can beat in price. Heck, the first one that opened here was right next to a Wallmart. Just imagine the nerve to do that.

they have the best alks - proven in tests.
