Just had to replace the batteries in a pair of Vtech phones (model
20-2481).
Old were nicad. New are Nimh. Differences? Best way to charge, how
often?

Figure some of the kind folks in here will have knowledge.

TIA

Use the new batteries as normal. The new Nimh type should have less of a
memory problem, and may last longer.

Since the charging circuit is designed for NiCad, it might cause
problems with the MiMh battery. I think the problem comes in on the
trickle charge, after the battery has been fully charged. Generally
the rule is, you can charge a nicad on a NiMh charger, but not the
other way around. But hey, if it works, it works.

LB,

You better hope the phone charger is designed to deal with NiMH
batteries. You can get a charger fire with NiMH batteries on the
trickle charge that NiCad batteries will cope with. NiMH batteries
mustn't have a continuous residual trickle charge.

I'd definitely not leave the phone charging overnight, when it might
be charged excessively.

You must be thinking about Lion batteries.
NiMH tolerate overcharging pretty much the same as Nicads.
A trickle charge is no more harmful to NiMH than it is to Nicads.
I converted all my cordless phones to NiMH a couple of years ago and
they're doing just fine.
Even my charger(Ray-O-Vac PS3) charges BOTH Nicads and NiMH.
Virtually ALL charging systems in cordless phones ramp the charge rate
down as the battery tops off so the OP should be fine with NiMH.
