Looking for a 24v battery charger; recommendations?



Two tasks: charging & maintaining



Does one charger do both well?

   Is your battery a "real" 24V device or a pair

   of 12s in series? 24V hardware is rare compared

   to 12V stuff. In fact, I'm not aware of any

   24 charger/maintainers but I'm sure they're out

   there. A Google search is the place to start.

   If you have a pair of 12s, consider a pair of

   Battery Tender like:

   I've found these "in the wild" for a little

   as $29 plus shipping. They recharge like this:

   You'll find a LOT of 24v battery service products

   but you'll not too that their prices are not

   nearly as attractive as the "wall wart" style

   tenders.



   Know too that Schumacher products sold at Wall

   Mart are now "smart chargers". See

   and recharge like this:

   Their smallest models are on the order of $20

   each and you don't need to pay shipping

We're using 2 Concord RG24-15 (24v,13.6AH) batteries in a Z14-FADEC system.



Our desire is to charge and maintain the main "A" battery via the ground 

power plug.



What issues are there with using two 12v chargers in series?



We already have a B-D 12v charger with the following details:

110 Amp Engine Start - 40 Amp / 20 Amp / 10 Amp / 4 Amp Continuous Charge 

Rates - Smart Battery Charger™

Model # VEC1093DBD

    3 stage, automatic, high-frequency charging technology

     Microprocessor control digital diagnostics & fault codes

     Spark-resistant reverse hook-up & overcharge protection

     Patented vehicle alternator check & engine start feature

     Automatic float mode monitoring

    Not practical. A 'smart' charger needs to see the

    battery that it's chartered to manage. When you add

    another charger in series, all bets for performance

    are off.



    I can sketch you the circuit for a 24v "tender"

    if you wanted to build one.
