Let me know if this should be aseparate thread :).
I am excited to see someone using the "L" designation!
I have two batteries that I got used, years ago. They have been, and continue to be, awesome. But I cannot find any info on them. They are MK brand, and labelled 'L7 gel' That is all. No group number, etc.
The MK website has nothing. Can you guys tell me anything? What is this "L" business? How many aH are my batteries?
