Depending on the battery.
Today almost all laptops, cell phones, cameras and PDAs use a lithium-ion battery. With a Li-Ion, you don't have to wait before recharging, the battery lives 2 to 3 years depending on quality, no matter how often you recharge it.
If you are talking about a very cheap cell phone (e.g. some low-end Sagem models), or about the typical AAA rechargeable batteries you can use instead of a usual battery, then it matters. They are NiMH type (other types have been manufactured in the past too, but you are ulikely to come across them today). They do not live a certain span of time, but a certain number of recharges. So it is wise to dicharge them completely before charging, some charger devices for AA and AAA batteries even do this for you. The other reason you should drain them out is that NiMH get "memory effect", which is bad for your device.
If you don't know what type of battery you have, look at the battery itself, usually there are specifications on it, including the type. If this isn't the case, contact your device's manufacturer.

batteries are regularly coated below guarantee for a era of 6-12 months. i dont think of previous this, any producer might choose for to amplify the guaranty era for a battery. charging the battery and draining it thoroughly is stated as Battery Calibration. at times the battery meter (the battery icon which u discover on the wonderful hand area backside of the workstation liquid crystal show, in abode windows) reflects incorrect analyzing. the meter might coach that there is 30 min fee left in the battery, however the battery would possibly no longer final for that long. to stay away from such incorrect battery meter readings, battery calibration is accomplished. previous this, i dont think of it would be of lots help. besides the undeniable fact that it relatively is counseled that u carry out battery calibration atleast as quickly as in a week.

These days you do not have to.
You might get an extra 5-10 minutes of battery life, but you don't have to.
