Thanks for the reply, however, there was no stamp on the terminal....I bought the car ('98 C80) used about 6 months ago..I have had an intermittent starting problem...starter turns only once without starting..the car always eventually starts though. Lately the car will hung up in high gear a couple times...3rd or 4th. Not fun when you are pulling out into traffic and go 0-60 in about 1.5 minutes. However shutting of the car and restarting corrected this. I supected maybe the battery is weak and causing electrical problems, and am going to replace it if I can confirm it is the original. I also had diagnostics run and the only code was O2 sensor. Any other suggetions with how to tell the battery year? Thanks a lot.
