Looking at online reviews, the Maha is a good charger, can't get much
info on the Lenmar.
A basic charger is just a transformer, rectifier, diode and resistor.
You charge it for a few hours, but have to remember to take it off
charge. A decent charger has a timer circuit which switches the
charging into a low current "trickle charge". A good charger has "-dV"
(negative-delta-V) which is a microprocessor detected change in cell
voltage(ie, it drops after the "bulk" charge portion of the charging
cycle) which then activates trickle charging. A great charger can
calculate capacity and perform reconditioning and rejuvenation of
cells. Even batter are the "Smart-Battery" systems which have ID chips
which calculate how much charge has been used since the last charge,
