Duracell LSD Made in China - OEM ID? Performance?

[StandardBattery]

Hi, I recently got some Duracell LSD black-tops made in China with a mobile charger. Has the OEM be identified for these yet? Is there any performance data?

IIRC, they are made by Yuasa Delta, which last I heard is who makes most of the alternate branded LSD cells such as ROV Hybrids.
