SLA battery charger

They explode quite spectacularly if overcharged.

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

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?

Thanks

Sounds like fun!

Then I would have to wear earplugs.

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!

Now we're talking!
