Electronics Question

I figured I would pose the following question here since this site is full of brilliant "techy" people. I recently bought a great little music system, a Sony "Personal Audio System" (RDP-XF300iPN). It has an Ipod dock, Radio, Bluetooth, audio input and a great speaker system, this thing sounds amazing for it's size! My question is as follows,

The system comes with an AC adaptor and a dedicated lithium-Ion battery (which is removeable by unscrewing a compartment). Once charged, the battery goes for 6-7 hours. Most of the time it will be sitting near an outlet, should I leave the battery in all the time continuously charging? It would seem to me the battery would last longer removed and then charged when I need it to be cordless.

The answer is not in the manual and have not seen anything that specific on the net,

Thanks!

I have a Logitech and I leave the battery in and try to mix play. Most the time on the plug and then every so often I play it on the battery till it runs out and then charge it up over night.

Rechargeable lithium batteries do not have the "charge memory" problem that rechargeable nickel-cadmium (Ni-Cd) batteries do. You do not have to totally drain them each time. According to what I have read (including my laptop's manual), to ensure the longest life and health of your battery, periodically, you should drain it by using until it shuts down.

I use a Bose Portable Sounddock. My son has a Bose Sounddock. We have always plugged them in and keep them plugged in until needed. I was working in the garage, a few weeks ago, and removed the Portable Sounddock from the power source and let it play on battery power. It ran over 8 hours. These new electronic batteries don't have that memory issue. You're good. As stated above, I like to let my electronic items run down and drain totally.

I would not leave it always on charge. I even keep my toothbrush unplugged except maybe every couple of weeks for a day. It really depends on how smart the charger is however.

The Nikon cameras also use Lithium ion batteries, and they say "remove the battery from the charger when charging is complete".

The lithium ion batteries go bad with 2 to 4 years of age (losing some of their capacity). Also the number of full recharges does the same. One philosophy is to simply use them, and replace them when necessary, they will need to be replaced when they don't hold much charge any more. Others try to maximize their life.

It is not necessary to run them down low each time. Recharging early and often is better than running them way down, which is actually harmful (because deep recharge is harmful). It is not necessary to charge them to 100% level either... 95% is just about as good. And certainly there is no need to continue to cook them after they are ready.

Here is a good article, perhaps deeper than general interest

One more note, my Bose unit doesn't continue to send electricity to the unit, unless it's needed. I only recognize that because the battery charging light changes colors after the unit is full charged. It let's me know that it's not charging. If not, I'd be concerned about my battery being fried. I think that manufacturers understand our needs and that these batteries won't fry, if the unit remains plugged in.
