You said "How can I safely discharge a large lead-acid battery?" and "How do I know when the battery is fully 100% discharged and completely safe". You did not say, I need this battery fully discharged. A halfway discharged battery is pretty much safe as far as I''m concerned. $endgroup$ –
How bad is it to undervoltage a 12-volt lead-acid battery?
$begingroup$ 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.
How to Properly Charge a Lead-Calcium Battery
When charging a lead-calcium battery, it is essential to use a charger that is specifically designed for this type of battery. The charger should be set to the correct voltage and amperage for the battery, and the charging process should be closely monitored to prevent overcharging or undercharging, which can damage the battery and …

How to Resuscitate a Deeply Discharged AGM Battery
To confirm that your AGM battery is deeply discharged, you can use a battery tester. Connect the tester to the battery terminals and turn it on. The tester will display the battery''s voltage and condition. If the voltage is below 10.5 volts, the battery is …
Battery Charging Do''s and Dont''s
General Charging Advice - Do''s. Batteries will self-discharge over a period of months even without a load.Many GEL, AGM and Calcium''s are better than regular lead-acid batteries but even so you should charge them back up regularly, or better still use a trickle charger (or solar panel) to keep them in top condition and extend their life.
Do I need to fully drain lead acid battery before charging them?
No, you should NOT fully discharge a Lead-Acid battery. The normal reason for wanting to fully discharge a battery is because some batteries have a so-called …
