Connect 25 AA batteries in parallel and series

[Besoeker]

Not wishing to sound rude, but I'm struggling to understand what is it you are trying to achieve.

I agree. A succinct and clear description of the project would be a great help. Is it for a Christmas tree, a fish tank, or a pot growing operation? Or all of the above?

It is for anything that I can use light for: for reading books, for taking washing off, for a bike ride, for use as a torch, for decorations on a christmas tree or christmas lights, to grow food indoors and much more.

I cannot be bothered to wade through all of the foregoing as I kind of think i know about Ohms law etc. But, from a practical standpoint, in my view you will be spending most of your free time changing expired batteries.
Dont forget that batteries deplete at different rates, How will you discover which ones need changing, or will you change a hundred batteries at a time?

seems to me a bit like shovelling the ---- out of a cowshed with a teaspoon.

There surely has to be a David Cockburn book on this very subject out there somewhere

This is why I decide to choose this battery instead, Eight Panasonic Eneloop AA batteries at 1.20 volts gives 15,200 milliamp hours. The Panasonic Eneloop AA batteries are rechargeable up to 2,100 times. 1900 milliamps on single charge times 2,100 is about 3,99,0000 milliamps hours. 3990000 milliamp hours divide by 6000 milliamp hours for one hundred light emitting diodes is 665 hours. The Panasonic Eneloop from 1900 milliamp in five years keeps 70% capacity, that means 0.70% times 1900 milliamp is 1330 milliamps in five years and loses 570 milliamps in five years time.

Update on right milliamps and hours for running one hundred light emitting diodes for the batteries. The batteries in parallel when 15,200 milliamp into amp is 15,200 milliamp divide by 1000 milliamp that is one amp is 15.2 amp hour from eight aa panasonic eneloop batteries. 6,000 milliamp from 100 light emitting diodes divide by 1000 milliamp that is one amp is 6 ampere. 8 AA batteries at 1900 milliamp hours are 15.2 ampere then divide by 6 ampere, that is one hundred emitting diodes means batteries last for 15.2, that is 2 hours and 0.53 times 60 minutes is 31.8 minutes. Panasonic Eneloop AA batteries cost £11.99 saving £8.01 in comparison to £20.00 worth of AA batteries that make 600 volts.

@Malooq Omar Tariq : You say that a particular battery loses 30% in five years. You do realise that, this will relate to loss of charge while sitting idle on the shelf ?.
It doesn't mean it will lose 30% over 5 years when under load.
You keep throwing up the same nonsensical figures in post after post, why ?. All this has served to do is waste the time of people that attempted to help you and alienate them.

Exceptionally, but wasting time & getting nowhere. He asked for advice & to be fair the guys have tried hard to give it.
All they get back is the same thing repeated, calculations that look like they've just been pulled straight from the pages of a text book.

Pop to a diy shop, buy a ready built LED torch, they cost about £3 and only take 3aa batteries'. Mines been used daily and still has the same batteries 6 months on.

This Malooq guy is taking the ---- with you all, if you truly are not taking the ---- Malooq then you shouldn't be connecting the LED's because you don't understand what you are doing or talking about.

Hello,

I have 25 batteries that are AA using 1.5 volts each, that is total = 37. 5 volts for 25 batteries. I want to know please the right way to wire all the batteries together to make a parallel and series battery pack. Please tell how to wire each battery together to connect all 25 AA batteries to make a parallel and series battery pack?

Thanks for your time and effort. Enjoy your day and have a good week. All the best for your successful future.
