Hi there,
I've got a basic problem that I can't figure out.
My vehicle has been sitting idle for the last month. When I attempted to start it yesterday, it made a fast "clicking" noise, when the key was turned as though the vehicle was run on an alternating current. The battery was replaced 2 months ago and I took it for a spin afterwards and it ran just fine, so this should not be the problem.
I hve checked all the fuses and battery leads, these seem to be fine. What do you think
forum?
regards
Geoff

If it is a modern 4x4 there are heaps of simple current draws!! Look at all the lights in gloveboxes, ash trays, door sills! Any number of these could be on an not realising it slowly draining the battery!
A month is also a looong time for a lead acid battery to be sitting idle! From the spec on the Century website any vehicle cranking battery will lose 50% of its charge in the first week of sitting idle!
Imagine if it also has a drain!!

Read on-: Most likely battery
Having said that the most overlooked thing can be connections. Over time and with water and the like, terminals on things oxidise which causes resistance. Dont just
check the battery terminals
check and clean terminals on starter motor and also
check and clean the connection of the earth lead where it joins to the chassis or block. Have you got an alarm on the car. Some alarms especially older or malfunctioning alarms can draw more than usual current. Even a half amp draw can flatten a battery in a similar time frame as you describe. If you are going to leave a vehicle for a month tis a good idea not to turn on an alarm. If all this has been eliminated to give you satisfaction and peace of mind, when the vehicle is running,
check the battery with a multi meter to see how many volts the alternator is throwing into it. Should be 13.5 volts. If 13 or under then it is not really doing the job when you are also operating a few accessories. 12 volts and with your lights on you are actually draining the battery. Hope you may have gotten some thing out of all that dribble. See ya later
