I was always told that the NiCad batteries always needed to be discharged almost completely or they would develop a charging memory and not charge properly, and this would shorten their life. I know this was accurate, and covered all nicad cell batteries, cordless tools, and more.
Now we seem to be seeing a lot of these lithium batteries in cellphones and other things. should these also be discharged on occasion, or can they just be charged on a regular basis before they completely drain?
I'm asking because the lithium battery in my cellphone is getting weak, and wont hold a charge very long. I have never intentionally let it totally drain. Most of the time I just plug it in after a days use. It seems it is now draining from a full charge even with the phone shut off, (I dont use it often), it will be dead after sitting a week and not being turned on all during that week.
