The Expedition Express has an internal, rechargeable battery capable of eight hours of continuous audio on a full charge. Even though the system may have some charge when first taken out of the box, we recommend fully charging your Expedition Express before first using the system.
To charge the battery:
• Set the power switch to the “OFF” position.
• Connect the Expedition Express to an AC power outlet using the included power adapter.
• Keep the system plugged in until the Battery indicator changes to green, indicating the battery is fully charged.
The Expedition Express utilizes a sealed lead-acid gel cell battery. When not in use, the battery will slowly self-discharge. If you are planning not to use the Expedition Express for a long period of time, it is advised to fully charge the unit before storing. It is also important to charge the unit every six months when not used. This will ensure a healthy battery and extend its life. If the battery is left with a very low charge for an extended period of time, it is possible to recharge the battery to working condition, but the charge time can take over 24 hours.
If you find that the operation time of the Expedition Express becomes noticeably decreased, even after fully charging, the battery should be replaced. Contact Samson customer service or your local distributor for a replacement battery.

I unfortunately didn't read the documentation and the battery had problems after 6 or 7 months of not being used... Exactly what I read in both this article, as well as a little pamphlet I later found enclosed in with the amp's paperwork.
Fortunately, after experiencing almost no charge and an LED that would show confusing, unreliable color codes, I left it charging for a few days. Now it seems to be working well enough. The LED will turn green after 2-4 hours of charging, but I've found it to be much more reliably charged if I ignore the LED and simply charge it over night every time. It's funky I guess, but it's definitely functional for the needs I have for now.
