How to wire and charge battery direct

How do I correctly wire and charge battery direct outside the device & and of the motherboard ?

The reason I ask this is because the charging port is damaged only 4 of the 5 soldering pins on the motherboard are intact so unable to resolder new micro usb charging port.

There are 3 red 3 black 3 white wires on the battery that connect to motherboard via plastic plug as I'm sure you already know - when the battery is fully charged the notebook works perfect I need to find a workaround to charge the battery direct
