I have a '98 GS400 which has a Lexus battery in it. The small circles for month and year were not removed when it was installed. I am the second owner, and I am trying to determine the age of the battery. Can anyone help me read the codes stamped into the plastic battery case? They are:

On top: E2FMK
On the front side near the top: 2E20AFGD

Thanks for your help!
