Batt-o-Meter

Shows hours of life remaining without removing the battery

Check hard-to-reach batteries via the 1/4" input on most instruments and effects pedals.

Fast, accurate, and easy to use, the Batt-O-Meter:

• saves you from risk and stress before a performance
• saves you money by extending the life of each battery
• saves you time by checking battery life BEFORE you take things apart
• save the environment by reducing the number of discarded batteries

The Batt-O-Meter looks inside your instruments and 9 volt devices to measure voltage and remaining hours of use.

Quickly and accurate measure:

• how many volts a battery is delivering
• hours left before the device runs out of power
• the remaining life in any 1.5-volt or 9-volt battery

Plug the gold-plated Power Probe into the 1/4" input on most instruments and effects pedals to test the life remaining in a hard-to-reach battery.

There's more! Test more battery types with increased precision: convenient slide switch differentiates between Alkaline, Rechargeable, and Carbon Zinc batteries.

The convenient right angle 1/4" jack enables you to check a hard-to-reach battery still inside of equipment. Just plug the Batt-O-Meter battery tester into virtually any battery-operated device with a 1/4" jack input and find out IF and WHEN to change its battery.

Stop wasting time and money - don't guess when to change batteries - KNOW with the Batt-O-Meter, the world's first battery tester for musicians.

(Requires 9 volt battery, not included)

Works only on normal negative ground pedals

This won't work on POSITIVE GROUND pedals like our germanium sunface, peppermint fuzz, or sunlion. To use it on these, you need to use an adapter cable that reverses the ground and ring on the stereo jack. We may try to make some up or modify the batt-o-meter if possible.

You can check to see if your pedal is positive ground by following the battery wire to the input jack. If the wire is black, it's negative ground and the Batt-O-Meter will work. If red, it's positive ground.
