The rechargeable Lithium battery in the unit should, when fully charged, have the ability to retain memory for 3-4 months. This retention period is slightly variable, and will slowly deteriorate at a rate of about 2-5% per year. At the end of the batteries life, it will essentially turn into a capacitor, capable of holding memory for about 10 hours when power is removed from the unit (internal and external). A full charge on the battery is realised after approximately 10 hours of the unit operating, or 5-7 days if the unit is not operating but has AA batteries installed. Charge times assume a fully discharged lithium battery. Lithium's are fortunately not affected by temperature. Because of the sensitive nature of waypoints, we recommend always storing the unit with a fresh set of AA alkaline batteries. If you have put a new set of alkaline batteries in the GPS for more than 24 hours and are still getting the 'memory battery low' message, then please return your unit to the address below, with an accompanying letter giving full details of the fault: ====================== -- Nomad
