About Photovoltaic Energy StorageDischarge time is basically the Ah or mAh rating divided by the current. So for a 2200mAh battery with a load that draws 300mA you have: $frac{2.2}{0.3} = 7.3 hours$ * The charge time depends on the battery chemistry and the charge current. For NiMh, for example, this would typically be 10% of the Ah rating for 10 hours.

About Photovoltaic Energy StorageIf the battery is bad, voltage should drop to lower than 12.6 in that time frame. The effectiveness of the battery to deliver continuous current can only be simulated with a load test; a simple load tester can provide an indication. Battery self discharge (loss of battery capacity without being connected to any loads) is battery specific.
About Photovoltaic Energy StorageWhen a lithium-ion battery is plugged into the charger, charging continues until 100% of the state of charge is reached. The charge is then terminated, and the Li-ion battery is allowed to slowly discharge. In Li-ion cells, the relationship between SoC and voltage is relatively flat throughout the cell''s discharge range.
