Guys,

Most of you know that replacement BMW batteries in the US were made by Douglas Battery of Winston-Salem, NC. They sold their battery division to East Penn manufacturing co. over a year ago.

East Penn now makes the replacement batteries, and they also offer them under their Deka brand name.

Most modern BMW's use the DIN H7 battery size (E39, E46, E53, E60, E85, E90, E91), part number 61 21 8 381 749.

This is equivalent to Deka battery, part no 694RMF.
