Can I use AA battery extender without internal battery?

Archived from groups: microsoft.public.pocketpc (More info?)

The extenders work as chargers... the power input goes through the ppc's
charging circuit to the battery which, in turn, powers the unit...

While it _might_ work, at the very least, you are putting your data and
all settings in ram at risk if you try it.

That's never worked on any PPC I've owned with removable batteries.

Yes- they work well in a pinch. I use 2000MAH Ni-MH rechargables in
mine.

Pretty much. Try not to run it all the way down- Li-Ion batteries
hate that. Keep it charged when not using it and the batts should
easily last you two years. I've never had a PPC battery conk out on
me before upgrading to a new model every 18-24 months.

I made my own extender for my iPaq 3660 using rechargeable batteries (4 x
NiMH AA and 4 x NiCd C) and used it for almost three years without any
problems.

I would not use Alkaline batteries as they have a higher voltage (unless you
only use three).

Am now using it for my XDA.

The question posted is if it would work with the ppc's main battery
removed or disconnected... did your setup do the same?

Thanks in advance,

Does keep it charged when not using it mean keep it plugged in? you
see, I charge it until i get 100% on the indicator then quickly
disconnect it from the charger. This is in the belief that
overcharging is bad.

>> This is in the belief that overcharging is bad. <<

Think you are being overcautious.

There have been no reports of any problems with overcharging with the
LiIon batteries used by PPC's and the charging circuits in PPC's... many
users (including myself) leave their PPC's in the cradle or connected to
chargers for most of the time they are not mobile.

LiIon batteries fare better being kept at or near full charge unlike
older battery technologies such as NiCad.

If anything, attempting to take the battery out of the equation puts
your data and device at far more risk than simply using it as
designed... you are going to have several hours use on the standard
battery alone that should last long before sleep takes over and you can
have a cradle or charging cord at the ready as the lights go out.

An hour and a half to two hours of wifi internet browsing every night
for almost two years on the Axim X5's regular, original battery rarely
takes the level below the 75% indication.
