Subject: [TowerTalk] Rechargable Batteries for a MFJ-259B Antenna Analyzer


> I recently purchased an MFJ-259B analyzer.  I want to go with Nicad or
> NiMh rechargable batteries.
>
> I'd like to know what type of charging cirucuit is inside the 259b.
> Theres an internal option to enable or disable its charging circuit.
>
> If I disable the internal charging circuit can I use an external
> nicad/nimh charger without damaging anything?  I have a specialized
> charger that charges NiCads, NiMh, Lithium's, ect that I use for my
> remote control airplanes.  It would be nice to use this so I wouldn't
> have to depend on the 259b's internal charger which would take up to 14
> hours to charge.
>
> Without a schematic of the analyzer I can't determine this on my own.  A
> call to MFJ technical support was not much help either.
>
> Thanks.
