Hi,
First I wanted to thank the handful of people that responded to my previous
question about HB batteries. We seem to be getting by using Fred's suggestions,
basically being more careful about charging, using ZAP mode to pull up really
dead packs, etc.
But, I'm still curious about replacing some of these cells, or eventually
having to replace them. DigiKey seems to not offer 500mAh AA NiCADs anymore and
I can only find them at one place (Jameco). Unfortunately, they won't create
the pack for me (as DigiKey would). That means I either have to build them or
use a battery holder (which would also allow me to maintain them more, ie.
replacing dead individual cells), which might change the form factor. Anyway,
long story short, does anyone know a good supplier for these? Alternatively,
what can I replace them with? What's going to happen if I use six or seven
hundred mAh cells?
An added bonus would be improving the power situation somewhat. In the later
portions of our class we pretty much fill up every sensor port on the board
along with two motors and a servo. We tend to have to keep the board hooked up
to power from the wall in order to run for more than a few minutes. In the
future I might think about using an additional power pack for many of the
sensors, but that's less than desireable. Is there some simple way to hook
another pack up to the board for additional power, or to swap in more powerful
batteries?
Thanks, and I apologize for my naivete about these matters.

| Replacement battery options are listed on the HB FAQ, at: (URL) don't you get the 1000 mAh packs from Radio Shack? That would give you 2x the run time of the 500 mAh packs. Take longer to charge, but would require no other board mods. Fred (...) (22 years ago, 12-Oct-02, to lugnet.robotics.handyboard)
