Thanks for the link, Chuck. I can't find the ones I purchased in the list,
but I see that it is about four years old.
I purchased from a California supplier who sells through Amazon, apparently
with a good reputation. We will see how they work out. The supplier
provides a 1-year warranty.
I have two chargers, the large, fast one that came with the E-1, and the
smaller, slower one that came with the E-510. I used the latter one to
charge these batteries, and will continue to do that.
