What's the cheapest way to make or buy an SLA charger for a smallish
(2.6Ah) battery?

** Buy one WES.

Arlec PS664 for circa $15.

Is it true that these batteries don't overcharge?

** Err - no .

They explode quite spectacularly if overcharged.

Can I leave it hooked up to a random power adapter overnight?

** If you wanna wake up with a BANG !!!

The adapter would need to be regulated right?

** No - it needs to be a BATTERY CHARGER !!

Can I just connect it to a car battery? I assume I'd need some of that
resistive cable stuff, not just connect it straight to the terminals

Is it true that these batteries don't overcharge? Can I leave it hooked up
to a random power adapter overnight? The adapter would need to be regulated
right?

Sounds like fun!

** If you wanna wake up with a BANG !!!

Then I would have to wear earplugs.

** No - it needs to be a BATTERY CHARGER !!

Damn. Those things cost money

a really cheap way is to have a "high" value risistor in series with the
phone line to suck a couple of mA for free!
