Battery charging calamity.
You know you can do a job, then wished you hadn't? Well I had that very thought after charging the battery last night.
Yesterday morning, I started the D3 and got the old "HDC Failure, Special Programmes Cancelled" flash up on the screen.
This means that it's time to charge the battery with a maintenance charge. I only do short trips so I put this quirk down to that. Charging the battery for 12 hrs does the trick for a month or so.
So I popped the bonnet, removed the cover and disconnected the + terminal. I know the - is the correct terminal to remove, however that isn't so easy as it's tucked away in an awkward position.
So the power to the vehicle is cut, this means locking the doors manually, that's easy. I then hooked up my charger, letting the bonnet close onto the catches without them latching. I've done this same routine a couple of times previously.
Knowing all is well I go inside for the evening. This morning I decided to power the old girl up again, knowing the battery has had a solid 14 hrs charge. I go to lift the bonnet and it's stuck. One of the catches has managed to latch in the night. We did have some strong gusts of wind in the night so I can only assume that was the cause. Oh I think to myself. Never mind I'll get in through the passenger door. I pop off the cover and insert the key. Well the key wouldn't turn that lock far enough to actually release the lock. I tried WD40, silicone spray and spray grease, nothing helped. I tried a bit more force and broke the key!!
Lucky the blade came out the lock but the door remained firmly locked. So now I'm stuck. The bonnet is latched on the near side and I can't get in through a door. So the only option without breaking a window is to release the bonnet. This is surprisingly easy. It took 2 minutes tops. I'm not going to say how for obvious reasons but I was easy. Once the bonnet was open, I reconnected the battery and all was well but it was much harder than I was expecting and I've still got to fix the now broken key.
I've also got to add a passenger door lock to my "to do" list.
So to avoid such a drama next time, I'm thinking of leaving the battery connected to the car next time I charge it. Your thoughts on this plan would be most welcome.Freelander SE 2005 Auto.

Make up a charging lead that plugs into the permanent live on your towing electrics. Then you just plug that in - job done. CTEK and other compatible ones available in the shop here http://www.disco4.com/shop/towing-socket-c...c-p45.htmlRich

Connect the charger via the towing electrics and leave the battery connected as normal, job done
Edit; beat me to it Clive

Definately agree with the above...when mines not in use it's parked on the drive plugged in via the Disco 4 supplied towing socket and a CTEK charger. Took the advice to remove the securing clip on the plug so if I do forget to unplug it and drive away it just pulls apart safely leaving the charging plug in the socket!
Great advice from the forum and a superb bit of kit....no bonnets left open..just a small unobtrusive wire running to the rear socket. Car is also left locked and secure without fear of theft...

If you do not have tow electrics then go underneath the vehicle and apply power to the lead going to the starter and the neg lead to a good earth. The alternator/starter has a permanent live so the vehicle will wake-up.

If I can leave the battery connected on the D3 as I do when I charge the battery on my MGF, I can just contact up to the battery with the croc clips. I just wasn't sure if the charger might upset the computers. I know my charger isn't regulated but the battery should damp out the supply ripple. My charger is only rated at 3.5 Amps RMS.

Your signature says you have tow electrics??
No problem charging the vehicle with everything connected but 3.5 Amps is quite small so would take an age to charge a flat battery.Land Rover - Turning Drivers into Mechanics Since 1948

Signature is now more accurate.
Normally if I need to charge a car battery, I just connect it up. However I wasn't sure if the ECUs in the D3 would be ok. My MGF gets a monthly 24 Hr charge because it's used as a fine weather play thing.
My old V6 Freelander obviously used less power than the Discovery, I only needed to charge it's battery once or twice over the winter.
My charger is called a 5 Amp but the label says 3.5 A RMS.
It takes a couple of days to charge a completely flat average battery. The good thing about using a low powered charger is it's safe to leave it contacted for a few days without over charging the battery.
I was surprised by.
A the door key not working. This isn't very helpful.
B how easy the bonnet was to open. Lucky for me it was but not good for security.Freelander SE 2005 Auto.

Just wondering if charging direct to the battery could have blown my oval timer now that is a calamity, it is to me anyway It can when others can't,
It will when others won't,
It goes where others don't.

If you use the adaptor in the tow socket with a Ctek in supply mode will this be good enough for flashing? I am guessing yes but just wanted to check.
