Batteries can be tricky and unpredictable. One moment they’re working fine and the next, they won’t start. If you are experiencing difficulty starting your tractor, it’s important to test your battery to see what’s going on.
In this scenario, the tractor owner noticed that their battery was getting harder to start. They tested the battery using a voltmeter and found that it had 13.27 volts. While this seems high, it’s important to note that just because the battery has voltage doesn’t mean it can put any power behind it.
The owner used a juice battery tester and found that the battery had 46 cold cranking amps out of 420. The state of charge was 100%, the state of health was 10%, and the resistance was 63.78. The resistance was high, which is a sign that the battery is bad.
The owner tested another battery, a Walmart battery, which had 12.33 volts. The battery had 196 cold cranking amps out of 275. While this battery isn’t perfect, it’s good enough to turn the tractor over.
Finally, the owner tested a new battery with 12.45 volts. This battery had 374 out of 300 cranking amps and was a good battery. The owner installed this battery in their tractor and was able to start it.
In conclusion, just because your battery shows 12V doesn’t mean it can start your tractor. It’s important to test your battery using a juice battery tester to see what’s going on. If you find that your battery has high resistance or low cold cranking amps, it’s a sign that the battery is bad and needs to be replaced.
