Firstly, thank you for your response. How long do you get, on average, from a set of lithium ion. Many thanks M Brown ----- Original Message ----- From: Walt Smith To: bookport@xxxxxxxxxxxxx Sent: Thursday, February 21, 2008 3:41 PM Subject: [bookport] Re: some info I've used my BP with rechargeable batteries in the past and have never encountered the slightest problem. However, I have switched to lithium ion batteries, since they give me the longest possible battery life. I use my BP heavily and this, of course, will directly determine how long you get on a set of batteries or, in the case of rechargeables, a single charge. The individual who said that they get "two or three months" on a single set of regular alkaline batteries mustn't use their BP nearly as heavily as I do, since I can't even get that long on a set of lithium ion batteries, let alone plain alkalines. ------------------------------------------------------------------------------ From: bookport-bounce@xxxxxxxxxxxxx [mailto:bookport-bounce@xxxxxxxxxxxxx] On Behalf Of M BROWN Sent: Thursday, February 21, 2008 7:17 AM To: bookport@xxxxxxxxxxxxx Subject: [bookport] some info Does anyone use their Book Port with rechargeable batteries.
