Got no code as yet for CCR2006 but need to replace battery. Would it be OK to connect battery charger to +ve & --ve batt. leads and switch over battery or is it better to use jump leads :-/

[tunnie]

depends how long you disconnect it for, might be ok without power. When i replaced the battery on father T's 2.2 (CDR 2005) i first ripped out the power sounder (it was annoying me) unplugged the battery, wacked the new one in, was without power for approx 1min, radio did not ask for the code....

Just gonna be a quick changeover but sods law dictates the radio will ask for the code. Wasn`t factory fit so carpass U/S

Have had mine of for upto 30 mins and when reconected did not have to put in code ...just reset the windows and sunroor settings

[RobG]

To cover my arse re; coding would it be OK to use the charger idea or no :-/

[tunnie]

can't see why not, those chargers are 12v, and without ignition on, its not going to draw a lot of power  :-/

I have used jump leads before

[RobG]

That was my thinking as well. I`ll give it a go, can`t see it doing any damage

Some battery chargers are pretty crude and without a battery as a load will generate high voltages which might damage something. Others will shut down if they don't detect a battery across their output.

Best way, IMHO, would be to get a small trickle charger from the likes of Halfords (little black mains adaptor with a pair of leads on) as these won't have the output to do any damage.

Failing that, connect a "jump start" pack between a ground connection and, for example, the alternator or starter motor b+ terminal so it's out of the way during the battery change. However, be VERY careful that the positive battery terminal doesn't touch anything during the battery change.

Thats the way I do it.  Take heed of Kevins caveat - a helper to steady the the +ve connector is useful!

Cant you disable the code before you take the battery off?

[RobG]

To disable the code you need the code
