Batteries... when will more Diamond or Stealth ones arrive?

[Tenebrae]

2 of my long term battery friends have recently started making noises about retirement. I was looking at what is available and didn't see any of the newer ones. I really love the draw on the stealth/diamond so I was curious as to whether there were any 'normal' ash cap batteries that have the same guts as the diamond/stealth series?

If not, when can we expect more to arrive please?

Nevermind, user error. I was looking under batteries and didn't notice there was a separate category for them
