Battery for Kodak z740 Digital Camera

allthedoyles

I need to buy battery for a Kodak Z740 Camera .

They are re-chargable Ni-MH 2100mAh 1.2v x 2

On eBay they come in 1800mAh , 2000mAh and 2500mAh

Can someone explain which is the best buy and do we need to buy 2100mAh ?

Once the voltage is the same then go for the highest mA value.
mA = milliamps
"mA x hours = mAH
(current capacity)
The current capacity measures how quickly a battery will discharge under certain circumstances. This figure is determined by multiplying the flow of the current from the battery into the circuit by the amount of time the battery is able to provide that current.


So,
Time = mAH/mA
If you are given the current capacity of a battery (in mAH), dividing this number by the current requirement of the circuit will give you the time of the battery will last under a constant load."

Thanks
I am going to buy the 2500aMh - should do the job .

Its an old camera , and the current batteries don't last long .


I don't think the current batteries are even lithium .
