Putting light bulbs in a charger circuit will not reduce the charge current, only the voltage. Unless the charger has adjustable current settings you can not use it to charge 270 mAh cells.

 

It will drop from 4 amp to about 2.5 on 6 cell. I would not think it will work on those real low MAH cells.

 

is it a 1157 automotive bulb(s)?? just one?

is it in series or paralel?

does it 'confuse' peak chargers?

thanks!

 

We use a 1157 with bothe filiments connected in series. I will work with some peak chargers but some of the new one it will not. It was made for the timmer chargers .

 

Thank you for the info....I will experiment.....or maybye just make my friend buy a charger!!!

The bulbs are acting like resistors. I believe if you put the bulbs in series with the battery you will lower the voltage to the cells. If you put the bulbs in parallel with the battery you will increase the current draw on the charger. If the charger only puts out 4 amps and the bulbs take 2 amps, I would think the battery would be charging at the remaining 2 amps. What effect that has on the peak detection circuit of the charger depends on how it's designed.

The best way it would seem to me would be to experiment with a trickle charger and keep track of how long it takes it to get the cells warm. That's how most low mah cells are charged.
