Battery charging

Is the battery charger supposed to be for 12 or 24 volt

Howdy,
It depends?

Are you looking at a charger to plug in, or a maintenance solar unit? Are you charging one at a time, or both batteries?

the battery charging system on my military generators are 24 Volt DC.

Are you talking about charging/maintaining your gensets batteries while unit is offline and not running? If so, you can use a 24V charger/maintainer for the two 12V batteries connected in series (24V configuration). Or, you can use two 12V charger/maintainers connected to each battery. I prefer to use two 12V charger/maintainers so that each battery is measured and charged independently so it gets exactly what it needs. If one battery were older or had a marginal cell it may required additional charging whereas the other battery might not. I think of a 24V charger as averaging the required charge between both batteries when connected in series.

Also, when using two 12V charger/maintainers it is not required to disconnect the battery leads (they can remain connected in series). The battery charger/maintainer only sees what is connected between its two +/- charging leads.

Obviously, for any genset model that utilizes a single 24V battery you must then use a 24V charger.

I actually went with a 24 V charger when I asked that question I was having a brain fart I left the terminals on and I connected the charger on to the correct terminals
Here is a pic

I use that really sticky 3M double-sided tape maybe not the best idea but I didn’t want to drill anything inside the generator housing did not want to cause any metal filings to scatter and I’ve seen this red 3M tape literally hold up curtain walls and big buildings

That should work nicely!
