I have the Maha unit. It now has one bay that is bad (several years of hard service) so I am looking for a replacement. 3v is not bad. I can make a DC power supply to feed it. Does it give the complete spec? as in 3vdc at 3a or something like that?

The Maha unit has a rather large back lit display

Ah,then this is perfect for you as the display isnt lit.

Output 3volt,2.8 amp per wall wart.

What the heck,its really hard to go wrong for 28 bucks for a smart charger.

If you get one make sure its the BC700,the BC900 had serious overheating problems.

One 'glitch',a REALLY dead battery wont charge,it wont recognize it.But if you stick it on a cheapo dumb charger for one minute its enough for the BC700 to see it and away you go.

Celler,gotta love those GSD's for sure.Black GSD,BTDT!
