Laptop Adapter FAQ2: My original has different output voltage and amperage from yours, does your replacement adapter really work?

Sure, we guarantee our replacement adapter work with your laptop or netbook if your adapter part number or laptop model number is included in our compatible list. Our adapter has +/- 1 voltage allowance. For example, our 19V adapter automatically switches its output voltage to 18.5V, 19V, 19.5V, or 20V accordingly when it is plugged in. It will be no problem if the output current (A - Amperage) of your original adapter is smaller than ours. For example, our 90W adapter (19V x 4.73A) can replace your genuine 65W (19V x 3.42A) or 75W (19V x 3.95A) adapter without any problems as long as they have same output voltage and connector tip. For tip size and shape, you can put your mouse on the adapter picture in product page to get a close-up image and read the details. Higher power adapter has no impact on your laptop because the laptop drawsbsas as many amps and watts as it needs while the adapter just provides as much power as the laptop draws. more ...

How to Charging the Li-ion Laptop Battery?
Claims of fast charging a Li-ion Laptop Battery in one hour or less usually results in lower charge levels. Such a charger simply eliminates stage two and goes directly into 'ready' once the voltage threshold is reached at the end of stage one. The charge level at this point is about 70%. The topping charge typically takes twice as long as the initial charge.
Depending on the Acer laptop AC adapter and the self discharge of the battery, a topping charge may be implemented once every 500 hours or 20 days. Typically, the charge kicks in when the open terminal voltage drops to 4.05 volts per cell and turns off when it reaches 4.20V/cell.
No trickle charge is applied because the Li-ion laptop battery for laptop is unable to absorb overcharge. Trickle charge could cause plating of metallic lithium, a condition that makes the cell unstable. Instead, a brief topping charge is applied to compensate for the small amount of self-discharge the PA-1900-171 FRU 92P1104 (ASTEC) adapter and its protective circuit consume.
