Car wouldnt start this morning and battery reading 11.66 v on the multimeter so time for a change I think.Looked to see the age of the battery and found this inscribed on the top of the battery....surely not 1979?

The number is
H3C110303 0379

  • Welcome to Motor Vehicle Maintenance & Repair! Considering the Jag is a 2009 model, might be the battery is also? (I can't see the image at work, so can't see the date code you're talking about). Oct 31, 2023 at 17:16
  • @Pᴀᴜʟsᴛᴇʀ2 I added the number as text. Oct 31, 2023 at 20:21
  • What brand of battery is it? Oct 31, 2023 at 20:28

  • If that is the actual date code for the battery, the "C" would indicate this battery was produced in 2017. I'm not sure this is the actual code you should be looking at thought. Nov 1, 2023 at 16:09
