The common sense about laptop battery

We can see the Voltage and Capacity on the laptop battery.Such as Laptop Battery APPLE A1417.The voltage is 10.95V.The capacity is 95WH/8460MAH.That is just the input voltage. The 100-240V says the power supply is a universal supply that will automatically adjust to the input (wall) voltage, depending on what your country uses. And the 1.2A is how much current it may draw. If the output voltage is the same, the 1.2A vs the 1.5A means it will take longer to fully charge your battery. It could however, be a bit stressed if you use the notebook while a deeply discharged battery is being charged (batteries draw the most current when deeply discharged).

However, it is CRITICAL the output voltage and plug configuration are the same. So that is where you need to concentrate your research.Think of a 12V car battery. If you connect a 9V charger to it, the battery will never fully charge. If you connect a 24V battery to it, the battery will likely over charge, and may catch fire. And if you connect the positive lead of the charger to the negative post on the battery, sparks WILL fly!

The current (output amperage) does not really matter for charging a battery. Low current will "trickle" charge - it will take a long time, but will fully charge. High current will "quick" charge but because batteries will only take what they need, there really is no such thing as too much charging current.Plug configuration matters because there are many different types. And even the same type plugs may be wired with different polarities with + on the center pin with this plug, and - on the center pin with that plug.

What you could do is what I did for my toolbag when I make "housecalls" is get a Universal Automatic Power Supply. Then all I have to do is make sure I select the correct connector and the "intelligence" in the supply determines the correct voltage and plug polarity. This Rosewill is a bit more expensive than most universal supplies, but it supports ASUS, ACER, Sony, DELTA, IBM, DELL, Compaq, HP, NEC, Lite on, Toshiba, Gateway, Delta, and Sharp notebooks (and probably many more), and I don't have to fiddle with output voltage jumpers or switches.

If you need a laotop battery,no matter original or replacement,I have a website maybe
