I want some 2v sealed lead acid batteries for a project, to drive the
heaters of some vacuum tubes which need 1.5v at 2 amps. At present I'm
using 6v batteries with big dropper resistors. I haven't investgated a
voltage regulator yet, though this would be a good idea.
I have a charger which can be set for 2.44v, and regular intervals up
to 6.88v (and beyond). If and when I get 2v batteries, can they be
charged at 2.44v? andy

In addition to the online sources, model shops - as in proper model
shops that sell radio control planes etc - sell them as the power
source for engine glow plugs.
