When your performance depends on good batteries—or if you repair guitars—the Batt-O-Meter is a must-have in your gig bag or on your workbench!

The Batt-O-Meter not only indicates the percentage of life left in an uninstalled 9-volt, AA or AAA battery, but better yet, its smart circuitry works for installed batteries, too! Plug it into a pedal, effects box or active guitar: it measures the power being pulled from the battery, compares that load to the battery's remaining energy, and calculates the remaining hours of battery life.

Use it before you go on stage and stop worrying about running out of juice during your performance. It's a must for troubleshooting in the shop, too. Save time by checking battery life before you take things apart!

• Ends guesswork about battery replacement
• Saves you money—buy fewer batteries and get more life out of them
• Helps the environment—minimizes discarded batteries
• Fast, accurate and easy to use
• Compact—fits easily into a guitar case or tool box.

The Batt-O-Meter is switchable for alkaline, rechargeable and carbon zinc batteries. It's designed for circuits powered by a single battery (highest testable voltage is 10.23-volts), and includes a 1/4" test plug.

Note: The Batt-O-Meter will work with normal "negative ground" circuits, but will not work with "positive ground" pedals. If the black wire from the battery connects to ground (on the circuit board or jack), it's negative ground and the Batt-O-Meter will work.

The lighted display indicates battery type, voltage, percentage of battery life, hours remaining of normal use, and low battery status.

The Batt-O-Meter is powered by its own 9-volt battery (not included) with self-test function.

It works, but it's not perfect

It works, but it's not perfect. Only reads the battery of my guitar's standard LR Baggs Element output jack if partially inserted, which is annoying. Works on some pedals but others, such as my PolyTune. Seems rather fat for what it does, taking up half of my guitar's storage space. But since there is no other device on the market that can check your battery while installed, it's a useful tool and one that I will not gig without.

The Batt-O-Meter is an excellent invention, as it takes out the guess work out of a Luthier like me when troubleshooting. It is so easy to use and detect the condition of the batteries. I strongly recommend it to players and luthiers alike.

I have other battery testers but I bought this one because it just plugs into my guitar instead of having taking my batteries out. I don't find it very accurate. Get different readings all the time. Not happy with it at all, I feel I can't depend on it.

Nearly excellent.

Why? Because it works on all my instruments but my Ovation guitar with nylon strings. Otherwise, I'm happy with it.

Works Perfectly!

Tests batteries in or out of the guitar or stomp box. What more could you ask for? One thing: a less cryptic read out code. I have to keep the cardboard packaging insert with it to remember how to read it. But then again, I have to look at my drivers license once a week to remember my birth date and how much I supposedly weigh....

Why didn't someone think of this about 450 batteries ago? Great tool for the repair shop and the working musician.

great tool to have

I bought this because I got sick of replacing the battery in my active bass in the middle of a gig or practice. Works well, the only issue I have with it is that I have to move the plug just right to get a reading, otherwise it's great!

Very Cool Tool!

If you have battery operated guitar/music stuff,(that's all of us right?!!) you NEED this! It works on most equipment. It's small, so it fits great in your guitar/pedal-board case.
I use this all the time. It also works on 1.5 volt batteries. Great value! Buy one, you'll like it!
