Do not use its "Slow charge" function.
My experience for charging a 3700mAh battery using Apex u+:
Charge current: Around 4A
Charge time: Around 55 mins
Final output voltage: Around 9.1V
p.s. Be careful sometimes Apex will false detect the peak, that means it'll stop much earlier than expected. Just re-charge it and take note on how many capacity did it charge before the false detection occur.
