Hey guys.. I was just wondering..

what is the best way to take care of an Ni MH battery? I'm using this type of rechargeable battery for my 360's controller. I've done some readings for my PSP Li-ion battery, and I was suprised to know that for the Li-ion battery (this means our PSP, our handphone, laptop and so forth), it is advisable to NOT DRAINING the battery to empty before recharge, contrary to some beliefs that if we charge our Li-ion battery before it is empty, it would slowly shorten the life span. The explanations were long, but it has something to do with the Li-ion battery having it's own "memory" to actually know how much power it has left and how many powers it needed to charge before it is full. Li ion battery will cut of the supply of power if it detected itself as "full". Hence there is also no such thing as an "overcharged" battery for the Li-ion case. 

The only thing that kill our Li-ion (the laptops are the most popular ones here) is the excessive HEAT when we charge our battery.   
I was wondering whether the Ni MH battery shares the same traits with the Li-ion. 

any experts here in LYN that is willing to share your expertise in this matter? 

thanks in advance!
