First a little background information: Good Battery. A good battery will sit around 12.6 to 12.8 volts when fully charged. When a good battery is put through a load test equal to its rated CCA (cold cranking amps) its voltage will drop to around 9.6 to 10.5 volts depending on the ambient temperature.

$begingroup$ Summarizing, the main points are these two: 1) Once a 12V LA battery is down to 10-11V, the voltage will plummet rapidly. No real point in pushing it farther (and risking point 2), given that you only get a few % extra current out of it. 2) If a multi-cell battery is discharged too deeply you risk "polarity reversal" in the weakest cell.

A typical lead–acid battery will exhibit a self-discharge of between 1% and 5% per month at a temperature of 20°C. The discharge reactions involve the decomposition of water …
You can load test your car''s battery with a "good" built-in hydrometer indication or 75% state-of-charge. Use the following methods: Use a battery load tester and apply the same load as half the CCA battery rating for 15 seconds. It''s the recommended method. By using a battery load tester, apply a similar load as half the auto''s CCA ...
The lifespan of a lead-acid battery depends on several factors, including the depth of discharge, the number of charge and discharge cycles, and the temperature at which the battery is operated. Generally, a lead-acid battery can last between 3 …
In fact it might be instructive to fully charge the battery and watch the voltage over time as it discharges. Put around a 1 A load on it and then take a reading every minute or so and plot the result. You''ll likely learn something about batteries in the process. Allowing a lead-acid battery to deep discharge can damage it.
