These are the Duracell
Pre-Charged batteries
which are Low Self-Discharge (LSD).
If they have white tops and marked made in Japan
then you have the re-badged eneloops.
The 15 min charger is not very kind to rechargeable NiMH batteries.
However it is a trade-off for having batteries quickly charged and ready, against their life-span.
But if you have at least two sets
then 15 minute charging becomes kind of superfluous -
LSD batteries as the name suggests retain their charge for up to a year
(use 6 months as a more conservative guideline)
so a spare set is almost always ready to use -
and one would then have up to about 6 months to charge the depleted set
