    Normally 10 years.

  2. Anyone know the shelf life of unused 625 mercury batteries?

  3. I think the manufacturers would disagree; perhaps 10 years 'til they're
    totally discharged. Back when I was selling them new, they were dated
    for about three years from when I received them. The mfg rep said at
    "expiration" the batteries would have about 2/3 of their original
    power.

  4. I wonder if they can be trickle charged, and kept at 100%?

    Mercury cells are generally primary cells, and not rechargeable. Depending
    on the charger used (or attempted to be used), the result may be anything
    from a waste of time to a call to a disaster.

  7. Yes. Well, I've had reasonably good luck doing this with other non
    rechargeable batteries....But you have to carefully choose a power source
    that just barely holds the battery at it's fresh voltage level, and not a
    millivolt more. All you're trying to do is stop any natural leakage from
    occurring, and not forcing current through the battery in the reverse
    direction.
