Last month we asked this Tech question and invited you to share your answer. We value your expertise and want to thank everyone who participated!
What is the correct method when testing NEW, never installed batteries?
When testing new, never installed batteries for charge, you should only check for open circuit voltage of 12.4-12.6v with a Voltmeter. If the voltage is lower than 12.4v you can use an approved charger to bring the voltage back to spec. To ensure longer shelf life, New batteries are not fully chemically formed, meaning that they need to be installed, and put under load (starter) a couple of times to get the plates fully saturated in electrolyte. After that you can use a capacitance or carbon pile to effectively test the battery.
