Answer / baadri

batteries in parallel increase the current rating...but the condition is that voltage of two batteries should be same.....

Answer / hari prasanth

Batteries connected in series:
Let us consider that we need to light a lamp of 24 V.
So we can use 4 six volt batteries which can be connected in series to constitute 24 V.(4 batteries * 6 V =24 V).
Advantage:
Batteries connected in series provide higher voltage with same capacity.
Batteries connected in parallel:
Consider the same scenario.
If four 6 V batteries are connected in parallel it will provide 6 V only.Also any any one is damaged (short circuited) it will become 0 V.
So it is mandatory to get 24 V battery.
Advantage:
Batteries connected in parallel provide same voltage but double capacity.
