My battery voltage reads 12.7 volts stationary but when i try to start the vehicle it does want to turn over… I tried it with a new battery that reads 12.5 volts and it starts effortless. How can i fix this problem?

Can you access the electrolyte? If so, you can measure its density with a hydrometer, a few $. Maybe the terminals need to be cleaned. Maybe a battery cable has broken. Maybe the alternator isn’t working and it isn’t getting a charge. Before you buy a new battery, take it in for a test. Even W…

This is how batteries die internally. Some say due to sulfation of the plates inside… some say because of the acid… some say both But they all call it the same thing… a dead battery. They dont last forever

Just have a conductance test performed on the battery In a few seconds, you’ll know the condition of the battery. [BATTERY TEST RESULTS] I haven’t tested the electrolyte in a battery in over thirty years, or done a load test on a battery in over ten years. Tester

You’re a working pro, with time constraints and the most modern instruments. I’m a retired DIYer with time to spare and reliable old tools. We both have something to offer here, for others to consider, or not.

I have not seen a modern battery, in over 20 years, where the electrolyte was accessible. I threw my hydrometer out probably ten years ago.

I recently bought one for about same price as you. At first I was a little disappointed because it wasn’t as accurate. But once I go used to it I trust it more than my cheap load tester.

12v battery reads good voltage but No AMPS

For the last couple decades or more, every one I’ve bought has two caps, each covering three cells. BITD they all had 6 caps. Either way, I can draw fluid out of each cell and test its state of charge by reading the scale on the float that’s inside the clear cylinder.
