Hi, all
Friend has a particular device that uses 3 Ni-MH AAA batteries. The problem
is that all chargers we saw charge 2 or 4 batteries. None will take 3.
What would be the easiest way to trickle charge 3 batteries at a time?
So far we have few ideas:
1. Build our own charger (not the easiest way out)
2. Have few sets of batteries so that even number of batteries can be
charged (messy)
3. Have some sort of a "battery emulator" that wll sit in a charger as a
fourth battery (just a wild idea at this time, did not really investigate
it).
Any other ideas?
Thanks,
Rudolf

Hi Rudolph.
If you need to charge 3 Ni-Mh batteries external to the device then
you can get them. Jaycar sell at least one that does this and is run
from the supplied 12V SMPS or a cigarette lighter plug. It has a
separate LED for each cell, and fast charges. AA or AAA batteries.

Trickle charge? Do you need to trickle charge, or is this just an
alternative?

Option 4. buy one from Jaycar :)

Hi Rudolf,
Considered buying 3 extra batteries and charging 2 or 4 at a time when all 6
are flat?

... or adapt an old mobile phone (eg Ericsson A2618S) that uses a pack
of 3xAAA NiMH cells. Then you'd have an AC adapter, a cigarette
lighter adapter, and an intelligent charger with a state-of-charge
display.
