So theoretically you would need to get hold of one of these special PD cables to safely pass 2.1A. Before this, the maximum you could send over a standard USB cable for battery charging was 1.5A @ 5v (and devices not being charged were limited to 100 mA or 500 mA). The gotcha is I can''t find any of these PD-aware cables available for sale.
The best way to charge sealed lead-acid batteries is to use a constant voltage-current limited charging method. This method ensures maximum battery service life and capacity, along with acceptable recharge time and economy. A DC voltage between 2.30 volts per cell (float) and 2.45 volts per cell (fast) is applied to the terminals of the battery.

USB Cables and Battery Charging. All BC1.2 defined battery charging mechanisms require the presence of D+ and D- within the USB cable in order to operate. If a cable that does not include the USB D+ and D- data lines are used to make a connection between a charging port and the PD, the PD is always limited to 100 mA maximum current draw.

desired current : 2,000mA D- : 2.0V D+ : 2.75V. Also, depending on how full the battery is the charge current is also limited. It will only be maximum when the battery is 30 - 70 % charged (these numbers are just my guess). Charging with a high current is bad for the battery when it is very low or almost full. Sources:

There is a charge controller chip inside the phone that determines how much current to put into the battery. Generally lithium ion batteries are charged with a constant current until the cell voltage reaches a specific level, at which point the charge controller switches over to constant voltage charging until the current drawn by the cell decreases to zero.
The maximum load current is 2.5mA when suspended, 100mA when connected and not suspended, and 500mA (max) when configured for that current. A device can recognize a SDP with hardware by detecting that the …
The battery shelf life is the time a battery can be stored inactive before its capacity falls to 80%. The reduction in capacity with time is caused by the depletion of the active materials by undesired reactions within the cell. Batteries can also be subjected to premature death by: Over-charging; Over-discharging; Short circuiting
