How old are my batteries?

Bus didn't want to start today. Had to jump start it with the car. Cells looked ok. Couple might be a little low. Alternator s running the bus but the voltage should ad higher if it's the same as old school cars. Doesn't move higher with rpm either.

They are still good cause the stickers are still on them.(jokingly)
I might be wrong but the guage shows battery voltage only with key on and not running but once started shows alternator voltage being supplied.
At least on my 86 bus and older vehicles I have mucked with.
Side note? You bus year ain't listed in your description so there is a lot of advice that could had from others here if they know the year your bus was created.

I don't mean to ask a stupid question or to insult you, but have you cleaned your battery terminals and checked the ground wire bolt on the frame? It's the simplest things that foul us up sometimes. Either of those having a varnish buildup will prevent proper charging.

Terminals look clean as do the battery stickers.

I'm used to seeing 12.8 or so when the batteries are NOT doing anything. When actively charging the voltage is 13.8. Needle never moved. After an hour of charging, it restarted again.

Didn't go looking for chassis ground.

Most auto parts shops will load test your battery for free. Getting that 8D out gets you a good workout in the bargain.

I'd put a charger on that sucker overnight then see what the voltage drops down to after a day or so. A good fully charged battery should stay around 12.7v for a few days at least.

Here's a pretty good website explaining alternator charging. According to the website your alt may be a bit weak.

Testing battery and charging system
No where it's parked.

Only read some of that page. Enough to know the guy makes bad jokes or doesn't know car radios. I don't think they ever had vacuum tubes. They filaments wouldn't stand up to the vibrations.

Aside from that, nothing I didn't already know,

If I had electric, I'd use a trickle charger.

Short answer: We don't know how old your battery is.

Search eBay for "vintage tube car radio." Apparently they were popular back before transistors came along.

Bet they didn't last long.

Was hoping one those numbers was a date code of some sort.
