TOPIC

    I would like to use Lithium rechargeable batteries in my MessagePad because they last longer than Alkalines. Do lithium AA batteries work with the MessagePad?


DISCUSSION

    Although Lithium batteries have not been officially tested, they appear to work well in all current Newton MessagePad models. The main differences between Lithium batteries and standard alkaline batteries are battery life and cost.

    The Newton OS uses a "battery discharge table" to approximate the charge status of the battery. When using rechargeable batteries in place of Alkalines, the Newton OS cannot tell the difference and will use an Alkaline battery discharge table. The result is that you may not have an accurate indication of battery charge status. Although this may result in the loss of data when the batteries run out unexpectedly, it will not seriously affect the operation of the MessagePad.
