[sdiy] Oscillator stability using SLA batteries.

[The Peasant]

Hi Julian,

Larger capacity batteries will result in slower discharge voltage drop and 
hence slower drift of any supply voltage sensitive circuitry. Transient power 
demands are better handled as well. For 1300mA I would use minimum 10AH 
batteries.

Take care,
Doug
