Is your battery really dead or does it just need charging? You can do simple field tests to find out. All you need is an inexpensive multimeter and some basic knowledge. Here I'll demonstrate the tests on three different motorcycles and explain what the voltage readings mean. The test results need to be be put in the context of the bike condition/use and battery age and then you can make a judgement about the need for a new battery.
I'll test resting voltage, surface charge, voltage drop under load, and charging voltage on a Triumph Bonneville, Triumph Tiger 800XC and a BMW R1200RT. Then I'll review the results and the next steps.
UPDATE: you can see the video on charging system testing here:
• Testing A Triumph Bonn...
These tests were done at about 70F/21C ambient temperature. In cold ambient temps readings are likely to be lower. Also, certain battery types such as gel batteries may require slightly higher readings to qualify as healthy. Check the manufacturer specs for resting voltage if you are uncertain. The charging voltage will not differ, however.
