high capacity battery not charging correctly

johnboyire

hi all

i have one of these batteries:

'Firefox' 9.6v 2000mah Ni-cd battery


and one of these chargers:

TLP Fuzzy logic Charger the one with the fan,


does anyone know the correct setting to use for one of those batteries? they have 8 cells.

thanks

John

cant remember the exact calculation, but my rule of thumb is for 2000mah, the max charging current i use is 2A, normally i just stick it onto about 1A and leave it on fast charge for most my batteries, (press the mode button twice i think for fast charge)

the number of cells doesn't matter, the charger will work that out itself

thanks,

what happens if the amps are higher when charging the dail goes up to somthing like 5

I would personally charge that at closer to 3A but its up to you. The higher ampage = faster charge but also an increased chance of damage.

I have the same charger and use 2.25 for 1400s

thanks guys

I always thought the slower the charge the better.

With Ni-Cd, 1A is about right for most packs. Ni-Cd prefer to be trickle charged, the lower the current the better. But if you must charge the pack fast, don't do it over 1A.
With Ni-MH, you can go much higher, though as a rule of thumb, I wouldn't recommend higher than the capacity if you can help it. IE, if it's a 2500mAh battery, don't charger it at currents higher than 2.5A. That rate will charge it in an hour from dead. Ni-MH's can charge at higher rates in a pinch, so if you're in a hurry, you can double the capacity, hence halving the time.
