Samson Expedition Express Owner's Manual

11

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.
