And then it says you can select the charging current, it also says that charger will do 3A on Bay 1 and 4, that’s high. The battery data sheet says 1.475A charging current (1475mA) and you can go a little above if you need a fast charge, but make sure the battery stays cool. Lots of fast charging cycles will harm battery life in the end, slower charges will increase the battery life.
If you can set the charger to “Li-Ion” and then choose ~1000mA (1A) charging current, you should be good to go. For a 3500mAh cell, a 1000mA charging current means it will take about 3.5hrs to charge from 0% (2.5V) up to 100% (4.2V).
There is a website called Battery University with tons of awesome info.
