Hello,
I own a Pacmate and believe me the battery life on a Pacmate is not very
good. I would also like to have a battery that we could plug into the unit
so that we do not have to send our BrailleNotes in just to get a new battery
installed. Even if it means redesign of the BrailleNote. Perhaps the
battery could fit into the bottom of the BrailleNote and could only go in
one way this would be much better than having to send our BrailleNotes to
replace the battery.
I have ordered my transplant and cannot wait to get my M power!
Virgie and Hoshi

Dear list,
This is Joseph. I would like to comment on this (actually a suggestion). A
lot of devices these days use Lithium Polymer batteries (those used on PAC
Mates). I have a quesiton for HW staff: are there any future plans to switch
from Lithium Ion to Lithium Plymer batteries?

Some very good points. However, a higher-capacity battery would
take development, too (I assume). As I have said before, I heard
about a battery that plugs into the power socket of the BN in a
2004 conference on the HW site. It seems that the better battery
could be developed to plug in, so that people would not need to
send in their units just to have the battery replaced with the
new one.
Because the battery is currently built in, a user has to send
their unit into HW and wait a few weeks to get it back, just
because of normal ware and tear. That is a major reason for my
opinion on the removable batteries. The slot into which that
battery would go could be on the corner of the unit, so there
would be minimal chance of a wrong battery being used, or of the
correct battery being forced in wrong and damaging the unit.
Just some thoughts.
Alex

1) the mPower will only do a discharge if necessary; if the
battery gauge
is accurate, it just does a charge.
2) I still think our adaptor is safer than the alternatives -
i.e. it's
almost impossible to electrocute yourself because any live metal
is
heavily recessed. Travel adaptors that aren't properly plugged
in could
have live metal exposed, which is not good.
3) Humanware would have to invest a reasonable amount of
development
effort to make a car charger, which would mean we'd have to not
do
something else. I think possibly we could agree that some other
manufacturer's car charger is safe to use, which would require
some
testing but not all the headaches of manufacturing something from
scratch.
I know a lot of people would like a car charger ... maybe if
enough
people ask Jonathan nicely ...
4) removable / external batteries have problems such as
mechanical design,
people inserting the wrong kind of batteries, or the right kind
the wrong
way round. It might make our lives at Humanware easier but I
don't think
that it would necessarily make a user's life easier. I think
we'd
probably be better off going to a higher capacity internal
battery
personally, but I'm open to arguments to the contrary.
apart from the first item, those are just my opinions ...
regards,
Andy.
