Improvement of the performance of the positive electrode in the lead ...
A beneficial effect of phosphoric acid is to inhibit the rate of the self-discharge reaction of the positive electrode in the lead/acid battery. However, adverse effects of phosphoric acid include capacity loss in the initial cycles, excessive mossing, especially at high H3PO4 concentrations, and poor low-temperature performance …
Effects of phosphoric acid additions on the behaviour of the lead—acid ...
The phosphoric acid can be used either during the formation process of lead pastes or an additive in electrolyte, resulting in reduced lead corrosion and self-discharge rates of the batteries [17]. However, as reported before, adding phosphoric acid in the pastes or electrolyte will reduce the battery capacity [18,19].

Lead Acid Battery Care and How to Restore Them
For older batteries I still recommend to start with just 2.5ml of phosphoric acid per 100ml of battery acid unless you already have a clearly visible phosphate layer or even white sopts on your plates that won''t fully disappear even after a few days of charging. These bad cases should get 3.5ml per 100ml for the initial dose of phosphoric acid.
