The first three need to charge laptop battery 12 hours do?

Start using the battery, the former three to be recharged for 12 hours?

This is totally unnecessary. Because the notebook laptop battery has a complete power management circuitry and charging management system, when the battery reached saturation, the control circuit will automatically switch to the circuit state, so long as full on-line, and does not mean that you can use the longer charge longer.

In order to prevent memory effect, we should run out before electric charge do?

Each charge before the pairs of notebook battery discharge is not necessary and harmful. Practice has proved that: the battery depth of discharge would unnecessarily shorten the battery life, when the battery is used about 10% when you can recharge. Of course, when the battery power is still more than 30% of the time advisable not to charge, because the memory Presario 2100(compaq 2100) effect does exist.

AC plug when the battery should win come?

Of course not! Although the lithium-ion batteries will naturally discharge the battery after a natural discharge, if there is access to power will appear repeatedly charge and discharge conditions, reducing the battery life, but this can not be won battery justification.

Now laptop power supply control circuits have this function - when the battery reached 90% (such as most HP models), or 95% before charging, while the capacity to achieve this through natural discharge time for 2 weeks a month. When the Presario 2500(compaq 2500 battery) battery is idle for a month or so to fully charge and discharge in order to maintain the battery capacity, this time you should be concerned about is the battery should "exercise their body," rather than being idle again after the recharge.

Even if the battery has "unfortunately" been re-charged, bringing the loss, it's not a long time do not drop the battery power caused much greater. Your data than your laptop battery or even your laptop are much more valuable a sudden power failure not only to your notebook computer has a injury, is unable to restore the data too late to repent of.

So, we often see what those who claim to what is used with an ultra-AA batteries compatible with the battery level what does that mean? In fact, purely a propaganda tool, Take the Sanyo to examples of each of the 18650-capacity batteries is very easy to distinguish ways of looking at the color of the battery cover to protect gas will know the capacity size. Sanyo Presario NX9010 battery assembly plants provided by the batteries to get after the matching assembly, thus matching the first (mainly the resistance of the pair) and then assembled, in this part inside the battery manufacturers and battery pack manufacturers do not distinguish between What is the so-called A + +. Then, on the market a new 2600mah batteries source of what is it? One is a real battery assembly factory inventories, that is, a certain number of the remaining tailings batteries, battery assembly plants in order to optimize the quality of the battery is generally refuse to use the residual tailings added a new batch of batteries inside the engaged in production; the second, that is, pre-production testing process, I found a variety of factors, does not fulfill the anti-2600mah batteries, but its capacity is significantly higher than the 2400mah batteries. Outside of these two batteries is a major source of sales of new 2600mah. Therefore, this so-called A + + what the stuff is completely merchants own standards, there is no basis. Moreover, the battery capacity and the English alphabetical order the contrary, B-level is the 2200mah batteries, which is frequently used Chinese-made Presario NX9000 notebook 4400MAH origin, and the price cheap and the most mature.
