AVR-Chat

Hi, Kat

    I have a product that I produce for more than 9 years and I have been
using NiCd's all this time. I tried many different brands and ended up using
Saft high temperature batteries. They are specified to work at continuous
trickle charge and really last much longer than other batteries I have tried
from panasonic and sanyo.

    Follows a link to the battery family that I use:

+systems&Intitule_Produit=VT

    I hope this helps....

Best regards,
Alexandre Guimaraes
