Thank you. Your post provided the encouragement needed for self-repair. Ordered the battery from Digikey sometime back and finally installed it last weekend. Easy job. Good result.

Thanks,

Or, do it yourself. It is simple soldering. Remove the top part of the case and you have access to the battery. It is a 1/2aa 3,6v Lithium battery. Cut and bend the ends to suit and solder it in.

Good luck either way
