Why would you not use rechargeable? Parallel rechargeable cells are fine.
The old zinc-carbon batteries could be charged a bit when they were
dead. I did that when I was a kid and had a transistor radio and
couldn\'t afford batteries.

I haven\'t tried alkalines.

What if I added a small diode to each one so that no reverse polarity was experienced by either(or more) batteries ?

If the two or more batteries in parallel are fairly equal in charge
and voltage, there shouldn\'t be any probllem.

If one is going to leak, then it\'s defective. There has been a lot of
leaky batteries lately it seems.

I\'m not buying Costco batteries anymore. I\'ve had half a dozen devices ruined by leaking Costco alkalines and the pack sitting on my shelf with dates of 2025 are leaking in the pack!!!

People suspect they are made by Duracell. One big difference is Duracell will pay to replace your device if it is damaged by their battery.
I stopped buying Costco Kirkland batteries a few years ago after the
whole package of AAAs appeared to be dead. I\'d heard they were
Duracell as well. Duracells are one of those brands that can leak.

I take my chances with them sometimes though. Just have to watch
them. I\'m sure a lot of them are OK.

Yeah, I found a very in depth review of batteries once that showed a pair of small dimples on the end of the Duracell and the same on the Kirkland batteries and none others in the review of maybe a dozen. So it\'s hard to imagine they aren\'t made in the same factory to the same spec. It would cost more to make them different.

The trouble with a \"lot\" of them being ok is you don\'t know if you have ones from that lot or the lot that leaks.

True, but I sometimes need AAs and AAA\'s and I\'m not sure what other
brands to trust. Certainly not batteries from the Dollar Tree !

So, I just have to take my risks and watch what I have.

Kinda new to picking out diodes, Can you guys tell me which one would be better for this application ?
Lets go back a step. Why are you wanting to do this?
What sort of voltages and currents are involved?

The obvious solution is just to use a physically bigger battery!

The only place I have seen AA batteries in parallel deliberately are in
some of the solar powered garden lights in Joule thief type circuits.

Provided that the batteries are matched from the same batch you probably
will only lose a tiny amount of capacity with a pair used in parallel.
But if you combine a mismatched pair then expect trouble as the stronger
one will try to reverse polarise the weaker cell causing leakage.

Batteries in parallel cannot reverse polarise. They have identical
voltage on the terminals.

Don\'t you mean in series?

See, that\'s my point. The Sunshine brand from Dollar Tree have been reviewed with testing and found to be as good as any. They are widely used and do not have the numerous reports of leakage that Kirkland and Duracell have. I had a Ray-o-vac battery leak and ruin a flash light. I contacted them about their warranty and I would have had to pay $10 to ship a $10 flash light. Instead I bought a $10 rechargeable flash light and use no more dry cells for that.

Your dismissal of the Sunshine brand is without merit.

Just to be clear, ALL alkaline batteries are subject to leaking. The problem is some brands are much worse than others. Costco Kirkland and Duracell are two that seem to fail much more frequently than others.

I bought a few of the Dollar Tree batteries myself and they were
awful. Very low energy from what I remember.

Maybe that review you saw was by someone who is pushing those
batteries

Point me to that review and I will have a look at their energy and
discharge profile. That will tell all I wold need to know except for
their leaking factor which may change from one to another.

Or maybe not. The review was of many, many batteries. Something like 20 different ones. Some tested well, others not so well. Do you really thing the review was a sham? Dollar Tree doesn\'t sell their own brand. They sell Panasonic, Sunshine and another US brand, maybe Ray-o-vac. Which brand are YOU talking about?

I think it\'s more likely you are making things up about whatever it was you bought at Dollar Tree.

Right. Sunshine brand. The biggest name in batteries.

Ray-O-vac... Who bought them ? Who bought Everready ? Who owns
Duracell now ? Or Sunshine ? Or Yamagoochi ?

A name doesn\'t mean much these days. Companies get bought and sold so
much you don\'t know much about any of them from year to year unless
you know for sure what kind of price reduction tricks or improvements

If I were to wire two or more alkaline batteries in parallel, sure I would double the Amp/Hours available to the load.

What if I added a small diode to each one so that no reverse polarity was experienced by either(or more) batteries ?

If the two or more batteries in parallel are fairly equal in charge
and voltage, there shouldn\'t be any probllem.

If one is going to leak, then it\'s defective. There has been a lot of
leaky batteries lately it seems.

I\'m not buying Costco batteries anymore. I\'ve had half a dozen devices ruined by leaking Costco alkalines and the pack sitting on my shelf with dates of 2025 are leaking in the pack!!!

People suspect they are made by Duracell. One big difference is Duracell will pay to replace your device if it is damaged by their battery.


I stopped buying Costco Kirkland batteries a few years ago after the
whole package of AAAs appeared to be dead. I\'d heard they were
Duracell as well. Duracells are one of those brands that can leak.

I take my chances with them sometimes though. Just have to watch
them. I\'m sure a lot of them are OK.

Yeah, I found a very in depth review of batteries once that showed a pair of small dimples on the end of the Duracell and the same on the Kirkland batteries and none others in the review of maybe a dozen. So it\'s hard to imagine they aren\'t made in the same factory to the same spec. It would cost more to make them different.

The trouble with a \"lot\" of them being ok is you don\'t know if you have ones from that lot or the lot that leaks.

True, but I sometimes need AAs and AAA\'s and I\'m not sure what other
brands to trust. Certainly not batteries from the Dollar Tree !

So, I just have to take my risks and watch what I have.

See, that\'s my point. The Sunshine brand from Dollar Tree have been reviewed with testing and found to be as good as any. They are widely used and do not have the numerous reports of leakage that Kirkland and Duracell have. I had a Ray-o-vac battery leak and ruin a flash light. I contacted them about their warranty and I would have had to pay $10 to ship a $10 flash light. Instead I bought a $10 rechargeable flash light and use no more dry cells for that.

Your dismissal of the Sunshine brand is without merit.

Just to be clear, ALL alkaline batteries are subject to leaking. The problem is some brands are much worse than others. Costco Kirkland and Duracell are two that seem to fail much more frequently than others.


I bought a few of the Dollar Tree batteries myself and they were
awful. Very low energy from what I remember.

Maybe that review you saw was by someone who is pushing those
batteries

Or maybe not. The review was of many, many batteries. Something like 20 different ones. Some tested well, others not so well. Do you really thing the review was a sham? Dollar Tree doesn\'t sell their own brand. They sell Panasonic, Sunshine and another US brand, maybe Ray-o-vac. Which brand are YOU talking about?

I think it\'s more likely you are making things up about whatever it was you bought at Dollar Tree.


Right. Sunshine brand. The biggest name in batteries.

Ray-O-vac... Who bought them ? Who bought Everready ? Who owns
Duracell now ? Or Sunshine ? Or Yamagoochi ?

A name doesn\'t mean much these days. Companies get bought and sold so
much you don\'t know much about any of them from year to year unless
you know for sure what kind of price reduction tricks or improvements
they have implemented. Also, their quality control. If any

You can send that link any time.
I just want to make sure I understand. Company A buys profitable company B so they can close down their manufacturing and do it somewhere else in a different way that makes the product crap?

Whatever. You are saying brands mean nothing which is clearly not true since we are seeing differences in brands and in particular we see two connected brands, made at the same factory, that seem to suck pretty badly.

Whatever. This topic is long since exhausted.

That has happened where a competitor was bought and ran into the
ground but that\'s not what I was saying. They will cheapen the
process to either increase profits and live off the name or lose the
magic of the proces that was there previously.
