A retest of a very good lithium AAA battery, has it change performance during the years (I tested it in 2013)?
The discharge curves looks normal for Lithium batteries, i.e. constant capacity also at high load. This battery holds capacity up to 1A current.
Conclusion
it is still a very good lithium battery, in fact it is slightly better at high loads, but capacity is the same.
