Dave: Getting the battery message at around 40% is unusual, but not unheard of. You need to check the level while playing an Audible book around the time that the unit is telling you to replace the batteries. It is likely that your batteries were dropping below the required voltage at that point, but were able to rebound substancially after stopping reading. This happens with some batteries.

After updating to 2.1.00.05, I was travelling and reading. I was reading primarily Audible material but did read a bit of etext here and there. Started getting the low battery message so I checked the level with D+F. They were at 46 percent. My unit would not continue to play then so let it rest a while. Started reading my Audible book again and the battery low message came within about half an hour. Again the unit refused to play further, so gave it a few minutes rest, after which I checked the level with D+F. It was at 40 percent. While this is far too high to actually need new batteries, I ditched them and put in a fresh set. Verified with D+F that they were at 100 percent then went back to reading my Audible book. After about 30 minutes, I stopped and checked the level. It was down to 79 percent. Volume on the bookport is set at 28, which is all I need because the Audible level is so hot. Have only used Alkaline batteries so this isn't a case of using rechargeable batteries. The battery drain I'm seeing seems excessive, so I thought it worth reporting. Additionally, assuming the gage was correct, why must I change batteries at 40 percent?
