battery prognosis

All,

A question please to the auto electrical aficianados here.

Just noticed my deep cycle AGM battery is reading 13vdc BUT registering full continuity between its pos and neg terminals. All wiring detached from both terminals.

Is it normal to register full continuity between terminals? If not, whats the prognosis for such a state? TIA.

Cheers.

Ken
Ken, Pumping 12volts through an ohm meter is just going to blow it up. The ohm meter works by putting a current through the probes from its own power source (usually a 9 vot battery). A smarter person than me could tell you how to measure voltage drop over a live circuit and work backwards to get resistance.

Greg,
Thanks Greg. The distinguishing thing between this battery and my other two batteries is that it registers full continuity between terminals, whereas the other two do not. Hence the query.

My digital multimeter is functioning as normal. I expect it has protection built in. Any other thoughts on this scenario please? TIA.
Cheers.

Is it doing anything wrong, not holding charge?

Greg,
Not sure. Just eliminating potential problem areas.
At this stage I'm after some guidance/answer to my specific query. Is this normal or abnormal battery characteristic?
Cheers.

Ken, you don't have a characteristic just a false reading.

Greg, the meter registers AND beeps full continuity for one battery, registers no continuity and hence no beep for the other two. All batteries at least 12.7vdc steady.

Put a fixed load on it and measure voltage and current, then use Ohm's law to work out the resistance. Then deduct the resistance from the fixed load and what you are left with is the internal resistance of the battery.
