Actuaqlly,Ithink not. most boards I've seenin recent yearsuse a cr2032
lithium, a non-rechargeable battery. theyt last 5-8 years because
they're lithijum.
a couple decades ago I had some boards with a small-cad battery, which
one might think was a good idea, but in 3-5 years they leak all over
the circuitry, ruining the board and/or other components.
