Hi Steve
   I measured the power requirement a while back and came up with 8 watts w=
hich is less than an amp. Right now I have the battery on a charger and it'=
s showing ~13.25 vts and < 1 amp on the 2 amp setting. I thought it might b=
e good to cycle the battery a little as you suggested.  I'm going to discon=
nect the charger until the battery voltage gets down to say just under 12 v=
olts and see how long it takes.=20

Hi Barry,=20

    A 12 V lead acid battery is fully discharged at about 11 Volts. They ma=
y have a 'working life' of about 300 full charge / discharge cycles. The fe=
wer cycles you put it through and the less the depth of the discharges, the=
 longer the battery will last.=20
