520T Back-Up Battery System Review May 17, 2007

Highly recommend this product as an add-on to any car alarm security system. If thieves manage to get into the hood and disconnect the car battery, the backup battery will power the alarm to sound. Another barrier of security for your car. An extra piece of mind when adding this to your system.

Any alarm installer will tell you that the first thing a fairly proficient thief will do is to pop the trunk ( very easy to do once you put your mind to it) and pull the battery wire. That allows him to work comfortably in getting around the alarm without calling attention. Someone with a open trunk may even draw some sympathetic looks from bystanders.
Well, if you are investing hundreds of dollars in a effective alarm system, it is not very intelligent not to spend a few bucks and get a stand alone battery.This also allows you to have a second hidden siren ( I have two) that keeps blasting after the thief has pulled the battery wire.He will realize he is up against a professional job and will move on to an easier steal 90% of the time.
If you have a remote transmitter that will also mean the car owner is on its way.Here in Chicago where the second amendment blatantly ignored, and a law abiding citizen is prohibited from carrying a firearm for self defense, that means you will probably resort to throwing rocks at an armed criminal or wait for the police so that you can tell them how you lost your car after the thief is gone.
Anyway the only thing that keeps me from giving a 5 star rating is that the battery does not have any indicator or link that will let know how much charge it is holding.

This product is quality. I have been using it with my civic alarm for over 3 months now. I have had no issues thus far. Easy to hook up, quality product. The only confusing part is the power. When hooking up the wires your your alarm, you use the power wire from the battery. You do not join it with a separate power wire from the car. The alarm is powered by the car through the battery during normal operation. When the car power is lost, the battery continues to power the alarm module.
