This may be more than you want to know but,
 
We have been using the lego pack and assume that after a year we may need to
replace them.  After season I'm going to charge up a set of eneloop AA
rechargeable and compare them to the Lego pack. The nice thing about the
eneloop's are that with a model BC-700 charger by LA CROSSE Technology you
can recondition the batteries again and again and remove most of the battery
memory problems.  I have old AA recharables that have been reconditioned and
I use them in my digital camera and they work like new. Conditioning takes
days but you just have to do it once every 3 weeks or so.
 
Once you have the recharger the batteries are a lot cheaper than the lego
pack.  I'll report back here on what I find out.

Subject: [VADCFLL-L] battery question


I have a few battery questions.  There was a lot of discussion about
changing batteries and I just wanted to clarify.  Did people say they had
better or worse performance when they purchased a new rechargeable battery?
And were you talking about purchasing an actual battery pack from LEGO, not
just new rechargeable AA's?  Does the battery pack just sometimes wear out? 

Also, is it bad to "overcharge" the battery?  Can we plug it in at night and
leave it overnight?  Some batteries can stay plugged in and they stop
charging once they are full and don't harm the battery.  Is that the case
with this one?

Thanks!
