A good pair of "Alkaline" batteries should last at least 20 hours in your Ear Force X-series wireless headset. "Heavy Duty" or "Standard" batteries will not last as long as Alkaline batteries. "Lithium" batteries may also be used. While these are quite a bit more expensive, they are supposed to last up to seven times longer than typical alkaline batteries.
Sometimes when a battery fails, it may leave 'crud' on the battery terminals inside your headset. If this happens, battery life will be decreased. You may use a Q-tip with some isopropyl alcohol to clean off the affected terminal(s). A good cleaning should restore the battery life to about 20 hours per pair (alkaline).
Alkaline or NiMH Rechargeable batteries are a good option. Even though they don't last as long, you can keep a second pair of batteries charging up while you use your first pair. When the first pair loses charge, swap them out for the second (charged) pair, and so on. It's a bit more work but will save you money in the long run -- especially if you play Xbox a lot.
Please note that the headset may have a shorter battery life in a dense RF environment due to data retransmission. We've found that using an X31, X41 in an area with a lot of other RF wireless devices working can cause the headset to use up batteries too quickly. This is the result of poor reception causing the headset's transmitter circuits to work too hard. If the headset's receivers "drop the line" repeatedly and have to constantly attempt to re-connect to the transmitter, then the headset may use up batteries too quickly. As a test, temporarily turn off all the other Wireless RF devices except for our headset and see if this improves the battery life expectancy.
Devices that may interfere: (this is only a list of what may cause the problem)
- A wireless home PC network ("WiFi")
- Cordless phones
- Wireless Xbox controller
- Wireless Xbox network interface/connection
- Wireless network adapters in several computers
- A neighbor with a wireless home network
The X31 draws approximately 35 to 50 mA in use, depending on the volume setting (the louder you play it, the more "juice" it will draw).
NOTE: Before deciding that you have a defective headset, make sure to test it with brand new, fresh-from-the-package alkaline batteries, just to make sure. Rechargeable batteries eventually lose their ability to hold a charge, so charging your own batteries may not be a valid test.
