Customer Reviews

Battery bug
A great way to know what kind of shape your battery is in before it lets you down.

great product
Much better than just the stock battery charge gauge, installs easy, looks good. I have an old mustang, doesnt get driven much so this really helps to keep an eye on things. Would be nice to have a remote monitor kit that mounts inside the passenger compartment though, I'd mount that in my glove box or something, but over all a really good product that will keep you from getting stranded!

Battery Bug works
I just tried the battery bug for the first time this weekend. It appears to work as advertised.
You attach it to the battery terminals and it gives you a count down while it boots up. It then gives you the battery's voltage output (volts). Then you start up the vehicle and it gives you a per centage rating of your battery. the bug flashes between percent and the batteries output voltage. When the vehicle is turned off, the bug continues to flash between the startup percentage and the battery's output voltage. I tried it on a month old truck and the percentage was 100%, as expected. I tried it on a Jeep which is only run in the summer but the Optima battery is kept charged and it gave an 88% rating. The batter was about 3 and a half years old under Phoenix (hot desert) use.
I won't know if it can predict a battery failure until I have a failure, but it appears to work as advertised on preliminary observations.
I appears to be an excellent inexpensive way to keep tabs on your vehicle's batteries.
