98 XJ8 L battery/electrical help needed
After setting up for a month discovered battery dead totally. Anticipating a new battery and hoping to drive to the auto parts store for the install, attached Duralast DL-80 charger. Immediate clicking in boot fuse box. Opened box and felt vibration in time with clicking in the 4 relays within the box. Disconnected charger and came here for help understanding what is occurring and direction I should pursue to get Old Girl purring again. Thanks in advance for advice, bNc

Yes on polarity, red on red, black on black, assuming the internals on this brand new "automatic" charger are wired correctly (smile) Will disconnect and try again. Thanks for the advice. Sometimes the obvious is overlooked (feeling dumb) Thanks again, bNc PS: upon entry, noticed same reset clicking behind glove box? Thanx

There's a very good chance you have a dead cell in the battery.
I and a few others, highly recommend some form of battery tender. I myself use the brand name Battery Tender (I have 3). These cars (much like Corvettes and I have one of those also) are notorious for bleeding batteries to death. I recently replaced my 11 yrs old Die Hard and went with an AGM Interstate Battery.
I travel a bit for work, so my car can sit up to 3 months. So getting 11 yrs out of battery using a Battery Tender, I feel, makes a statement.

In our 98’ XJR, even with the glovebox “closed”, the light stays on because you have to push on the left side to fully “close” it. I think over time the whole assembly warps a little bit (??) and that’s why it does that. To be honest, there are several modules in our cars that can malfunction and won’t go to sleep mode properly which drains the battery. That would need further diagnosis with a multimeter to see what your draw specifications are.
