What's the approximate lifespan of the battery? I think the clock has kept good time and I really never had to fuss with or adjust it but now notice it has lost two minutes since last Fall at time change. It's not much or a problem but now noticeable. Scanner now 5+ yrs with battery being original and properly charged when new and also maintained occasionally with wall charger. No need for alarm but how long are they lasting and is it something you yourself can buy and replace or is sending it in for service needed once it goes.
