Amps Answered

Can anyone tell me what happens if you take two 1.2v, 1900mAh  rechargeable batteries in parallel connected to an LED?  Does it increase the amount of time the LED will stay on?   I'm new to this.  Working with small solar charging lamps.  Thanks Patty

Two batteries in parallel will give you twice the amps or run time - in a perfect world.
In reality both batteries should be identical, best new ones to avoid too much self discharge.
In series you get twice the voltage and slightly les max amp than from a single battery.
That is why 9V batteries are so weak - 6 1.5V batteries in series and they all tiny...

Thanks for your reply. Does run time mean that the batteries will provide power for a longer time? Also, can I set up two 1 volt 80mAh solar panels joined in paralell and then join 3 of them in series so I have a solar system of 3 volts, 2400 mAh panel.

Do some readup on solar panels and how to protect them ;)
You need to seperate them with a diode, this will use some voltage so with these tiny cells you are lost.
