Ha, I do like their return policy though.

Ok, I found a battery - $24.00 - 12V 4.5amp so therefore I am going
to only get 1.5 hours out of the monitor, right? Ok, I also picked up
a female sleeve for a 12V lighter - but it is called "VDC 12V", is
that the same?
I guess I am going to have to spend more money to get a larger battery
with more Amps, right?

I went to Canadian Tire to find the 12V cordless
drill batteries

There's problem one. Don't go to Canadian Slime.



Yep... that's what I'd suggest as a starter. You still need to do the math and
figure just how long you need to operate the monitor from battery. It's the
single most important piece of information you need to have. Next, use the
charts on that web site that I posted for you to calculate the approximate run
time for a given AH rating.
Generally speaking, the higher the AH rating, the longer your monitor will run.
Charging the battery is another question altogether. If you don't feel
comfortable constructing your own charger (and from your previous questions, I
gather that you don't), I suggest that you look for a charger that has normal
charging with automatic switchover to float charging. Use Google.. search for
SLA battery charger.
