Eliminator Intelligent Battery
Guard<http://www.canadiantire.ca/browse/product_detail.jsp?FOLDER%3C%3Efolder_id=1408474396672454&bmUID=1186416721356&PRODUCT%3C%3Eprd_id=845524443294641&assortment=primary&fromSearch=true>
Product #11-3001-4
An innovative accessory that easily installs onto any 12V car battery
----------------------------

Price is not up to $69, but I sure it will sooner or later come on sale
again. It was in the weekly flyer a few weeks ago at $27. That's when
I bought it.

Like Dennis pointed out, there are many brands of these voltage
controlled relays, with slightly different voltages and extra features.

I wanted to open mine up to see what's inside, but it looks like all
compnents are molded into epoxy. The relay must be of some kind that
doesn't require a current to hold. Standby current is only 10mA which is
probably what the electronics for the voltage sensing circuit and
radio takes. (yes it comes with two wireless control units too keep
in your pocket or on dash)
