Self-Discharge: The dormant / self discharge characteristics of Pale Blue batteries are very low. This is one of the advantages of a lithium ion battery with a control circuit, vs an alkaline or NiMh battery, where the cell discharges directly into the circuit (no control circuit). The battery life in dormant mode depends partly on the environment. High ambient temperatures, and higher humidity, increases the internal drain. But in normal circumstances a battery installed in a device, like a door lock, will last ~12 months.

Robust!

Life in a lav mic is never easy. The 9Vs and AAs breezed through 4+ hours of operation barely diminished. What I appreciate most is, chargers and all, the compact space needed in the audio bag and that I can charge them on the way to the gig.

Best Rechargeable 9V Batteries We've Tried

We use these batteries to power some of our rental equipment. They're the only rechargeable 9V batteries (out of dozens we've tried) that hold a full charge and deliver enough power.

Best Batteries for Guitars

Pale Blue 9V is perfect for acoustic electric guitars and active pickup guitars that require a battery. Standard batteries leaked and corroded one of my acoustic electric guitars that is played less often than the others. After repairing the guitar, I decided that all of my guitars with built in tuners and active pickups deserved to have the best, so I replaced them all with Pale Blue. Now I don’t have to worry about damaging my expensive guitars with harmful (environmentally and monetarily) batteries.
Do yourself a favor and protect your investments and the environment.

Excellent Batteries, Don’t Do What I Need

I was excited to get two rechargeable 9v batteries because I am a musician and need two 9v’s: one in my guitar and one in the e-bow I have. The e-now works great! The battery is strong and I get good tone, but the battery in the guitar is a big huge nope. As soon as I put the Pale Blue battery in the guitar I started getting this really loud hum and it’s definitely the battery. I’m pretty disappointed because that’s the battery I go through the most and I’d like to find a better solution than throwing away 9v’s every couple months. I’m definitely a convert though. I think when I’m ready to replace the batteries in my headlamp/non-audio electronics I’ll definitely be getting more Pale Blue batteries.

The best battery ever

I never write reviews, however I have to say I put on in a smoke detector and it lasted longer than a name brand, and I can recharge it and replace not throwing anything away!

Make the switch, trust me you won't be disappointed!!
