Title: Battery maintenance voltage on 732B
Post by: kkayser on April 20, 2017, 03:41:20 pm

The maintenance voltage on my 732B is 14.9V.  I would like it somewhere in the 13's.  Does anyone know which resistors control the maintenance voltage?

Do you mean that the charge indicator is off and it is floating at 14.9 V?

Yes.  The charge light has been off for over a year.

Do a forum search for '732B battery'. This has been covered in detail in a couple of threads, including charger mods and PCB revisions.
