LRP Pulsar touch charger help

[Jason A]

I have bought one these chargers in the post month or so and have noticed the following and wondered if others are getting this?

When charging a lipo battery it takes a long time to finish the charge as it seems run the mah down to really low like 0.09mah charge and seems to do a kinda trickle charge at end.

It's been charging great and never had pack run out it's just my old charger did the same charge in 25mins where as the LRP does it in 40mins

Is this normal for this charger ?
