Batteries in Parallel ......

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

But I run into other problems ? Would one battery overpower the other can cause one of them to corrode/leak etc ...?

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

Thanks

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.

Similar batteries in parallel should be OK. The far ends of a
cylindrical battery are already in parellel.

I like Panasonic alkalines as my Valu-Time brand, they\'re $2 for a pack
of 4 AAs at Ocean State Job Lot. Never had them leak on me, and had a
pack in storage for 4 years before use, seemed fine.

It\'s hard to go by anecdotal evidence and pretty much all battery data is anecdotal. But one advantage is buying in 4 packs rather than 40 packs. I have a AAA monster pack and two AA monster packs I\'m going to try to get a refund on at Costco. They are also going to get a look at the meter they ruined and see if they will compensate me for that.

I like the Sunbeam brand sold in dollar stores, Dollar Tree I think. They are cheap $1 for a four pack and they haven\'t leaked yet. They also rate well in life tests. Dollar General batteries seem to do ok too, but they cost significantly more. They do have decent reader glasses for $6. lol. At the Dollar Tree everything\'s just a dollar and sometimes that\'s just not enough to get something even worth \'free\'.

Maybe. It depends on the battery chemistry.

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

Schottky diodes are good for that but you probably don\'t want one diode per
battery if you have a lot of batteries.

That must be costing them a fortune then.
All the recent battery leaks I have seen have been Duracell batteries.
I have moved over to Panasonic or Everready as a result. YMMV

I found some info on \'Schottky diodes\' and some more info on \'Germanium diodes\', both seem to have very common properties.
Low forward voltage < 0.3v , Low reverse voltage < 20v, high leakage current in the mA(s).
Kinda new to picking out diodes, Can you guys tell me which one would be better for this application ?

You can get a much better dropout with a FET but it will vampire drain a bit of idle current and require some support circuitry.

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.

IIRC they used a pulsing technique with short periods of charging and discharging. However, they would not work with a genuinely flat cell.

Nah, I\'ll pay $2 for a 4 pack of Panasonic AAs at a local store and not
send all my cash Amazon\'s way. Not sure where they get \'em from or why
most brick-and-mortar stores don\'t carry \'em (Duracell and Energizer
might be unhappy) but they\'re a solid battery.

As for Ikea what I mean is they discontinue a practical desk like the
Jerker and you see a work desk like this in the store for $600.

It\'s not that I do not have $600, but I can do better for $600. Y\'know,
like some other products from that area of the world you could mention
like BMW and Volvo.

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

But I run into other problems ?  Would one battery overpower the
other can cause one of them to corrode/leak etc ...?

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

Thanks

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 like Panasonic alkalines as my Valu-Time brand, they\'re $2 for a
pack
of 4 AAs at Ocean State Job Lot. Never had them leak on me, and had a
pack in storage for 4 years before use, seemed fine.

It\'s hard to go by anecdotal evidence and pretty much all battery
data is anecdotal.  But one advantage is buying in 4 packs rather
than 40 packs.  I have a AAA monster pack and two AA monster packs
I\'m going to try to get a refund on at Costco.  They are also going
to get a look at the meter they ruined and see if they will
compensate me for that.

God bless.

I like the Sunbeam brand sold in dollar stores, Dollar Tree I
think.  They are cheap $1 for a four pack and they haven\'t leaked
yet.  They also rate well in life tests.  Dollar General batteries
seem to do ok too, but they cost significantly more.  They do have
decent reader glasses for $6.  lol.  At the Dollar Tree everything\'s
just a dollar and sometimes that\'s just not enough to get something
even worth \'free\'.


Even Ikea isn\'t that cheap, anymore...

Cheap, cheap, cheap. Always cheap. Are you guys on minimum wage or
something?

The Amazon batteries seem fine, no driving/parking/standing in line
for refunds required.


Nah, I\'ll pay $2 for a 4 pack of Panasonic AAs at a local store and not
send all my cash Amazon\'s way. Not sure where they get \'em from or why
most brick-and-mortar stores don\'t carry \'em (Duracell and Energizer
might be unhappy) but they\'re a solid battery.

Kinda new to picking out diodes, Can you guys tell me which one would be
better for this application ?
Click to expand...

What application?
What volts are needed at what amps and for how long before replacement
batteries are needed?
Is this for a portable device? What are the space/size/weight constraints?
Room temperature or wider temperature range?

Thanks
Sid.
