I have a few remote sensors that needs 'embedding' in inaccessible
positions but which have to last for years (ideally 10 years).
The problem is that the mains supply will be cut off for 8 to 14 hours
every day and completely for 3 days or so every 4 to 6 weeks.
I thus need a battery that will spasmodically (4-6 weekly) be
discharged down to (say) 30% of capacity (or whatever is prudent) and
daily be discharged a few percent and subsequently recharged.
What battery chemistry am I looking at here and how must it be
electronically handled.
