Why did you change to Li-ion?
Not for longevity: NiMH will last 2-3 times as many discharge-charge cycles as Li-ion.
Do you live in extreme cold areas? Li-ion does perform better in frigid cold compared to NiMH.
The only other real benefit of Li-ion is that it will homd its charge a little longer than NiMH. Personally, though, Indon't charge up HTs and then not use them for six
months.
