![]() ![]() One thousand Milliamperes equals 1 Ampere. Because size and weight of laptop batteries is limited when compared to larger batteries such as car batteries, most companies show their ratings with Volts and Milliamperes. What is the run time of 's laptop battery?ĭynapack laptop batteries have two main ratings on them: Volts and Amperes. NiCad, NiMH and Li-Ion batteries will self-discharge during storage remember to recharge the batteries before use. ![]() If a laptop battery has not been used for a long period of time, perform the new battery break in procedure described above.īattery Storage - If you don't plan on using the laptop battery for a month or more, store it in a clean, dry, cool place away from heat and metal objects. ![]() We recommend using the battery at least once every two to three weeks. This helps maintain a good connection between the battery and the portable device.Įxercise the Battery - Do not leave the battery dormant for long periods of time. Keep the Dynapack laptop Batteries Clean - It's a good idea to clean dirty battery contacts with a cotton swab and alcohol. Exceptions to the rule are Li-Ion batteries which do not suffer from the memory effect. Prevent the Memory Effect - Keep the laptop battery healthy by fully charging and then fully discharging it at least once every two to three weeks. There are several steps you can take to help you get maximum performance from your laptop battery: How can I maximize the performance of my Dynapack laptop battery? The Li-Ion is stronger and has longer run time.Ĭlick here for information on calculating Dynapack laptop battery run time. Ni-MH: 9.6 Volts x 4 Amperes = 38.4 Watt Hours Li-Ion: 14.4 Volts x 3.6 Amperes = 51.84 Watt Hours If your device does allow you to upgrade the battery from NiMH to Li-Ion, you will typically get longer run times.įor example, if your laptop uses a NI-MH battery that is 9.6 Volts, 4000mAh and the new li-ion laptop battery is 14.4 Volt, 3600mAh, then you will obtain longer run time with the li-ion battery. It will automatically list all of the battery chemistries supported by your specific device. Please refer to your manual to find out which rechargeable battery types the laptop device supports or use our Dynapack Battery Finder above to find all the compatible laptop batteries for your device. NiCad, NiMH and Li-Ion Dynapack laptop batteries are all fundamentally different from one another and cannot be substituted unless the laptop has been pre-configured from the manufacturer to accept more than one type of battery chemistry. Not sure what this really means.Upgrade my Dynapack Laptop Battery from NiMH to Li-Ion When the battery level reduces to around 25%, the two values shown are pretty much the same. For example, when Menu Bar first shows 100%, the difference is around 4%. The original problem that I reported above is still seen.Įdit 2: As the battery level goes lower, the difference between values shown in Menu Bar and System Information keeps reducing. It restored the apps and open windows (does that mean it just went to deep sleep?). ![]() It stayed at 1% for some time and then the MacBook turned off on its own.Allowed the battery to drain all the way.What can cause this problem? Does it look like a hardware or a software issue? But if I look at System Information > Power, it shows: When the light on Magsafe power adapter goes from amber to green, the battery status on the Menu Bar says 100% charged. I never bothered to check these with the previous battery. I am observing a difference in charging status depending on where I look. ![]()
