Not on that device, but:
(1) It lets you select the battery. So the "device" isn't actually "a"
device.. It is many :)
(2) You'll need to get familiar with the lead/acid chemistry...
If this was me, I'd be looking at a simple uController with decent
analogue and USB/Network. You'll probably just need to look at the
battery voltage and maybe put a current shunt in to see what happens
when it is being sucked dry... The cheapest source of suitable widgets
is probably the Arduino form factor kit - the ATMega controllers are
12bit analogue which is probably enough to figure depth of discharge.
Shouldn't be very complicated - the analogue signal conditioning side is
the hard part!
