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)

  • Great idea !!!!!!!!!!!!!!!!!!!

I bought this from Interstate Music about 5-6 years ago and have used it since to check any 9V batteries that power onboard preamps on my many acoustic/electric guitars. One can check alkaline/carbon-zinc/ or rechargeable batteries. The meter has a "pigtail" cord that plug into the guitar's input jack or if you have a pedal,into that, and it displays the status of the battery Also has a positive (+) and negative (-) terminal that you can press the terminals of new batteries in before you place them in the battery compartment of the preamp or pedal. The meter gives a display of current voltage, estimated life of battery, among other features. A convinient way to check !!!!!!!!!!!!! GET ONE !!!!!!!!!!!!!!!
