Book Courier recommends alkalines; the status recorder (the amount left) works well with those. Some people are also using lithium (nonrechargeable). If you use rechargeables, you have to go to the settings menu and change the battery type from nonrechargeable (the default) to rechargeable batteries. Did you do that when you used NIMH batteries? The bottom line is, nonrechargeables are recommended. - Jackie McCraw ----- Original Message ----- From: Andrew Ireland To: bookcourier@xxxxxxxxxxxxx Sent: Monday, February 20, 2006 9:52 AM Subject: [bookcourier] Best type of Batteries for the bookcourier Hi All, Not had my BC for long so looking for information on Batteries. What would you all recommend for normal type Batteries and rechargeables. I had some NIMH Batteries here but I didn't get long out of them. Many thanks in advance for any information Andrew
