We get a lot of questions about short battery life. This is usually fixed by adjusting settings on your ToneWoodAmp!
I personally get around 7 or 8 hours of battery depending on settings and how I play.
Some things to consider:
For example, if you read 3.6 on your batteries, and you start to strum, it may need to draw 3.8V if you drive it hard enough, causing the batteries to shut off due to signal peak.
Low battery indicators will trigger at certain voltages if they stay within a lower threshold for 30 seconds.
You can also adjust the DIM settings which will dim the screen sooner and conserve battery life.
The most common setting to adjust is the Master Gain % from the global settings. A lot of people tend to crank that up way too much expecting it to increase the overall volume of the TWA. That is not the purpose of the Master Gain. It is there to set the incoming signal level TO THE EFFECTS. It will increase the output volume of the TWA, but too much will cause clipping and feedback. I personally set my Master Gain between 5% and 40% depending on the guitar or pickup.
I hope this will help you adjust your TWA to conserve battery life.

I just ordered some to try out! Thanks for the recommendation.
I hear this daily.
We do out best to make sure people know to unplug the patch cable from the preamp, but not everybody reads the instructions. :)
It just depends on the guitar, I guess.
I've got a few guitars with K&K pickups and external preamps, so I don't have to worry about unplugging when I'm through since I don't use the preamps with TWA.
My Taylor with the ES-2 is another story... About twice a year I forget to unplug it myself. lol.
Luckily, I've switched entirely to rechargeable batteries, so It's never an issue.
When I'm working with those, I use a bendable claw tool to pull out the battery bag and loosen the E and A strings a bit to remove it. Those little claws are a lifesaver and can reach just about anywhere in the guitar saving you a lot of time.
...let,s not forget that we set the guitar initially at 50% volume. Try upping that to 75% and lowering the master gain (maybe 10% to 30% range). If things still sound good, you'll find battery life increases.
just a question regarding this :

You're talking about a 9V block battery here right? Can you tell me what you've found that fits? Thanks
Funny story about those 9V... They fit great, but they were some no-label Chinese batteries I purchased from eBay that no longer work
They held up fine the first two charges, but now all 4 of them will not hold a charge for more than half an hour. They're junk at this point.
Eneloops are still going strong, however!
I bought an Energizer rechargeable that is too large, so, for now, I'm back to using Coppertops.
