Difference in sizes of batteries used?
-
Anyone knows what is the real reason behind the different sizes of batteries used on different equipment?
Like the old pagers uses AAA size, touchlights uses D size... -
There is big equipment and there is small equipment.
Simple enough a reason?

Be it AAA or D size, they all use 1.5voltOriginally posted by charlize:There is big equipment and there is small equipment.

Because of Capacity.
AAAA is also 1.5 but low capacity.
D is 1.5 but higher capacity.
But now with technology, the rechargeble AA batteries have more capacity than a D size alkaline.
but if you want to compare among alkalines.... obviously. D has most. -
apart from obvious reasons like size...voltage is also a factor...example...there is a rectangular sized battery..it supplies 9V per battery...but those cylinder sized ones provide 1.5V each.Originally posted by sbst275:Anyone knows what is the real reason behind the different sizes of batteries used on different equipment?

If I'm not mistaken, I was once told by someone that it's all due to the capacity of the battery cell. The bigger it is, the higher capacity it holds. That's why when I do my project previously, I uses a C size battery instead of AA as chose over by my friend and my project work lightings last longer.

Also C is bigger than AAOriginally posted by photo_seeker:If I'm not mistaken, I was once told by someone that it's all due to the capacity of the battery cell.

obviously A is bigger than AA.
D bigger than C.
no, i am not talking about batteries. -
related to the capacity of the charges it can store bah. like a water bottle with 2 litres of water can last you longer den a water bottle with 1 litre of water bah.

Simply becos different equipment has different current consumption. Different Batteries size used it to meet the no of hours the equipment is able to use with the batteries.Originally posted by sbst275:Anyone knows what is the real reason behind the different sizes of batteries used on different equipment?

Bigger size batteries can store more current, thus it's rating in mAH is higher (comparing to the same material used in the batteries).
Batteries has evolved the same as electronics - miniturisation. Thus, new materials are studied to give it a higher mAH rating in smaller size now. -
Now sbst275 knows.

There is only AAA and AA.. Dun have A..Originally posted by Ponders:Also C is bigger than AA
obviously A is bigger than AA.
D bigger than C.
no, i am not talking about batteries.
But how come those kechil ones that are used for calculators are 3V? -
wah lao eh.... read the last line of my post properly leh.Originally posted by sbst275:There is only AAA and AA.. Dun have A..
