Equivalent ACER Laptop Battery

As technology advances, so do power ratings. The Acer notebook battery you bought last year may be twice as strong this year, and might even be the same physical size. Batteries have two main ratings on them: Volts and Amperes. Because laptop batteries do not carry a very large amount of power when compared to larger batteries such as car batteries, most companies show their ratings with Volts and Milliamperes. One thousand Milliamperes equals 1 Ampere. When buying a battery, always go for the battery with the most Milliamperes (or mAh). Batteries are also rated by Watt-Hours, perhaps the simplest rating of all. This is found by multiplying the Volts and the Amperes together. We will now show you an example of finding the Watt-Hours for our example battery.
Our example battery is 14.4 Volts, 3600mAh
(remember that 3600mAh is equal to 3.6 Amperes).
14.4 x 3.6 = 51.84

This battery has 51.84 Watt-Hours. The term Watt Hour signifies the energy needed to power one watt for one hour. Thus this battery can power 51.84 watts for one hour. Suppose your laptop runs at 25.92 watts (this may be unlikely, but let's use this just for simplicity). This battery could power your laptop for 2 hours. People usually associate the word 'Watts' with light bulbs, and yes, this battery could power a 40 watt light bulb for about an hour and 18 minutes, a 60 watt light bulb for about 52 minutes, or a 100 watt light bulb for 31 minutes; it's the same idea.
The reason we have shown you watt-hours is because oftentimes the volts and Amperes vary. For example our laptop that uses a Li-Ion 14.4 Volt, 3600mAh battery may use a NI-MH battery that is 9.6 Volts, 4000mAh. Now let's do the math and find out which battery is stronger.

Li-Ion: 14.4 Volts x 3.6 Amperes = 51.84 Watt Hours
Ni-MH: 9.6 Volts x 4 Amperes = 38.4 Watt Hours
The Li-Ion is stronger.

How long does a acer laptop battery last? When should I consider replacing mine?
All rechargeable batteries wear out with time and usage. As time and cumulative use increase, the performance will degrade. For the typical user, noticeable reduction in run time generally will be observed after 18 to 24 months. For a power user, reduction in run time generally may be experienced prior to 18 months. We recommend buying a new acer laptop battery when the run time does not meet your needs.

How should I choose between two batteries with different Watt hours (Whr) available on one system?
Higher Watt hours (Whr) on the same system under the same operating conditions will generally deliver longer battery run time. For example, if you compare the same system, running the same applications, the 53Whr battery would provide approximately 65% more run time than the 32Whr battery.

How do I charge my acer laptop battery?
The battery charges in the laptop when the laptop is connected to an AC power source via the AC adapter.

How long does it take for a acer laptop battery to fully recharge?
The charge time varies depending on the system. If the system supports ExpressChargeTM , the battery typically will have greater than 80% charge after about an hour of charging, and fully charge in about 2 hours with the system off.

Should I totally discharge, then recharge my acer laptop batteries occasionally to make it last longer?
No, discharging and charging does not increase the life of a Lithium Ion technology battery.

Can a acer laptop battery be "overcharged"?
No, the battery is designed to stop using the charger when it reaches full charge

Is it easy to install a acer laptop battery?
Yes, very easy. First, make sure all open files are saved. Next, either attach the AC adapter directly to the laptop or set the system to "hibernate" mode or shut off. Release the latch on the current battery, and simply install the replacement battery.

What does acer recommend for battery storage for a long period of time?
When storing for more than 4 days these guidelines can better preserve the life of your battery:
1,Do not store batteries for long periods plugged into or attached to any power source. This includes AC adapters and laptop security carts plugged into an outlet.
2,Laptop batteries, including those stored in laptop systems, should maintain an Operational Storage Temperature of 0° to 35°C (32° to 95°F).
Batteries may be stored in the laptop or outside of the laptop.
3,Charge batteries before storing. The recommended charging time should not exceed 1 hour. Typically, this should charge the battery to between 80% and 100%. (Some discharge will take place over time. Stored batteries are expected to discharge 10-15% over a four month period, for your information.)
