Thread: Battery warning fault.

Have you checked the earth?

Checked the voltage after charging last night, 13.56v. This morning down to 12.60v. Off to the stealer where the foreman ran several checks and eventually announced the battery was on it's way out.
New battery installed and away I went.
Approx. 30 months doesn't seem much of a long life for a battery as big as the originals are in LRs.
Thnx. for the comments.

Hi Alan and if your battery was showing 12.60 in the morning, that's at over 95% SoC.

I suspect they replaced a good battery, but you are laughing.

Good one.

As Drivesafe said, 12.6 is almost fully charged. Readings over that are a float charge, but put the battery under load and it would drop back to about 12.6.

Mine also lasted around 30 months & the start car message came up.

We weren't near a dealer at the time so I had to stump up the cost of a new one.
Although I have had a Traxide system fitted since the car was new the battery still failed & if it wasn't for the Traxide, I would never have got it started when the message popped up.

Same. My last AGM lasted four years before giving errors. I’m hoping with regular CTEK charges this one might last longer again.

As per my previous post,mine is 5 yrs old,and gets regular charging with the Ctech.
Looking at the date code,its actually 6 yrs old,but has been in the vehicle for 5.

I also have a switch on the SC80 earth wire so i can turn it off and charge each battery separately,and reduces the current drained from the battery by the SC80.Our vehicle is not used a lot at times as we have company vehicles.

The D4 also 'wakes up',whenever a door is opened,or unlocked,so the sitting voltage of the battery is lower for a few minutes,then it eventually creeps up and stabilises.
