Keith McMillen: Batt-O-Meter - Effects Pedal Battery Tester

The First Battery Tester for Musicians, Batt-O-Meter lets you check batteries INSIDE effects boxes and guitars without having to remove them. Plug the Power Probe into your ¼" jack and read the voltage and hours of remaining life. Also check external 1.5V and 9V batteries.

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 accurately 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.

Note: Requires 9 volt battery, not included. In order to test AA and AAA batteries, they must first be removed from their device.
