Hey, I have LG HG2 20A batteries and when I charge them it is okay but when it is almost full it the charger gets stuck at 90% though it says that voltage is 4.2. I thought I just need to wait, but I waited for 15min or so and still the charger was stuck at 90%. But the interesting part it showed that it was still charging, I mean the mAh's was slowly increasing but percentage stuck at 90%..

The charger is new. What should I do?

Have you tried this on your regulated mod to charge the batteries?
What is the brand of your charger?

Have you looked around through web searches to see if there are known issues with the charger you have purchased?

Your issue is one of two things and should be easy to determine.
1. Bad charger. Try charging some other batteries, what happens?
2. Try charging the batteries in something else, what happens?

The outcome of either or both of these tests will tell you which device is your issue. If you have a voltmeter you can test the batteries themselves and see what the final charge is when they come out of the charging cradle. What is the battery charger you are using?
