So been having a few probs with low batt warnings on my rr, latest I think is the dsp playing up, bought one of the voltage checkers, [as suggested by nicedayforit cheers] and plugged it in yesterday, battery was showing 12.1-12.2v, and when I started it, it went to 14.2/3v, so I will put it down to mainly short runs, and I have only done about 400 miles this month, its not the daily driver/ family school run car, [wife just changed her saab aero for a nearly new mondeo titainium 1.6 tdci ecobollocks, £30 per yer to tax and 45-60 mpg], so I have just put it on charge with my optimate, to see if I can make it last just a bit longer, as I still have a few things I want to get to get done and getting a new battery wasn't on the list lol, lets hope this will recover the battery a bit, it has a Unipart battery in at the mo, but will replace with a bosch if and when it needs one, I have connected direct to the battery terminals without disconncecting it, im pretty sure this is ok????

Hi Hammie,

I have had similar issues for the past few months, with it gradually getting worse and more and more errors showing when I startup and switch off.
The battery eventually died on Wednesday, fitted a new Bosch, and no errors at all now

Cheers

im hoping I can eek mine out until march, fingers crossed, will leave it on charge over the weekend and see if it will hold the charge 2003 ffrr v8 vogue

You know it's going to let you down at the most inconvenient time / place !

I hope you have a good set of jump leads & don't park anywhere remote...

Fortunately I have a Clarke 12/24v jump start battery pack, which I ended up carrying around with me.
The last week before it finally died, I had to use the pack each time I started the car.
Like Alistair said, make sure you have some decent jump leads or carry a battery pack like I did.

luckily I can pick and choose when I use it, afraid to say it spends quite a lot of time on the drive at the moment, but being retired, I don't need it to be ready to go at any time, I will give the battery a charge, [although its never failed to start, or show signs of struggling] and see how it goes, have the AA if worst case happens, I think maybe I can get away with a charge up, watch this space lol 2003 ffrr v8 vogue
