Yes, these are made by East Penn, same as the "Werker" sold at Batteries Plus stores. I am told (but have not confirmed) Batteries Plus continue to sell relabeled/private label East Penn Batteries, but now under the Ray-o-Vac brand name.

185Hr reserve capacity and the 20Amp hr rate is 100. Looks identical with the OEM, only black. very happy so far. Here is a link
- hit the application guide.
The East Penn "Deka" batteries are awesome in performance, and can also be purchased in the Absorbed Glass Mat configuration (AGM) which are totally sealed, never need water (really) and have an even longer life span than typical liquid cell batteries. I believe the standard Deka for E39 sells for around $130 to $140, and the AGM is around $170. But shop around, I found a Batteries Plus store that sold me mine for $93 (three years ago), and the date code on it was recent, only a month or two old.
