real quick question

This depends on what kind of battery it is. A NiCd (nickel-cadmium) battery should always be fully discharged before you recharge it because they will develop a 'memory'. If you keep recharging them before they are discharged, they will lose their ability to hold a full charge. NiMH (nickel-metal-hydride) batteries can also have charge problems, but not as bad as the older NiCd batteries. Li-ion (lithium-ion) batteries don't seem to have this problem. I've read where a new NiCd or NiMH battery should be charged and then fully discharge several times soon after you get them. This helps the new battery hold a full charge. My old laptop's battery (Sony) just died. It was a Li-ion and lasted five years and I never took any precautions in charging it. ---- Still works fine (with the 110 AC line cord plugged in) it just won't last but about 2 minutes on the battery. Check the back of the battery. It will tell you the composition of the battery.

It's a Lilon Battery,and i didnt know there was a little read me sticker inside but it said to charge for 10 hours before usage

OF30,
Just about anything you buy that has a rechargable battery will instruct you to charge it for an extended period of time before using it the first time. With it being a Li-ion battery you can charge it as needed for a log period or short period or run it off AC power (and charging) without damaging the battery's life.

TheOutfielder30,

My new Toshiba laptop has a Li-ion battery. The handbook has the following caution:




I generally pop out the battery since I rarely disconnect and move my computer.

Infidel-08, I did some checking and Li-ion can be damaged by overcharging. Some manufacturers warn against continual charging and some don't. I did research as to why and I find the voltage applied after full charge (trickle or boost charge) is the reason why. If the voltage remains high after full charge the plates can become damaged and shorten the life. (Some will heat to a dangerous level). I did read about some laptops actually catching fire a while back. If the trickle charge decreases to a "safe" level the battery is protected. Since we don't know how each peice of equipment responds during the charge cycle your suggestion of limiting charge time should be heeded unless otherwise indicated.

Charging lithium-ion batteries

It shouldn't matter what you do with it. Li-ion batteries don't have a memory, so you can charge them whenever you like. I am a bit surprised about the Toshiba warning, though. The battery should have a chip in it that keeps it operating safely (not being over charged or over drained) regardless of what you do to it.

They might not have a memory, but they do have a life. My old one is dead as a doornail. I think it's prudent to remove it from my stationary laptop. Do you disagree?
