![]() This is part of the system’s battery protection mechanisms. When the battery temperature is too high or becomes overheated, battery charging capacity will be limited or even stop. Batteries charged or stored under high ambient temperatures may have permanently damaged capacity and accelerated battery life decline.* A battery’s charge initiation capacity (%) is usually set between 90%-99%. ![]() To extend battery life, when a battery maintains 90%-100% power after being fully charged, the system may not recharge due to battery protection mechanisms. Frequently charging a battery under high voltage will quicken its aging.When a battery-charged laptop is externally connected to additional USB or Thunderbolt devices, the battery power will also discharge faster. For example, running computation-heavy programs, such as graphics software, gaming software, and video playing, consumes more power than running general word processing software. The battery’s discharge rate depends on the laptop’s or tablet’s software operations and power management settings.High/low operating temperatures and abnormal operations may result in 60% or more rapid decrease of the battery’s life cycle within a short time. Battery life decline varies with the system design, model, system power consumption, program and operating software consumption, and power management settings.Afterwards the battery capacity will drop to 80% of its initial capacity. Under normal usage conditions and in ambient temperatures (25℃), the Li-ion battery is expected to discharge and recharge normally for 300 cycles (or about one year). The life of a Li-ion battery is approximately between 300-500 cycles.Due to the chemical properties of Lithium ions, battery capacity decreases gradually with use over time.The onboard battery and surge protector helps smooth out the power flow the reduce the chance of damaging to your equipment.More ASUS Battery Information Center Last Update : 9 When you look at it this way, the UPS' job is to ensure you don't lose any work rather than to let you keep working for hours when the lights go out.Īpart from blackouts, a UPS is also useful for coping with power brownout and spikes. It could be particularly important if you've servers running in your back office. Some UPSs even connect to your computer via USB and let you automate this process should disaster strike. ![]() Instead a UPS buys you time to save everything, put your Plan B in place and then gracefully shutdown your essential systems. Large businesses looking to run an entire office for hours during a blackout generally put a diesel generator on the roof, but that's obviously not practical for most businesses.Ī smarter strategy for a small business is not to try to ride out a blackout. This isn't to say that a small business-grade UPS is useless, just that you need to be realistic about what it can do. ![]() We will not share your details with third parties.Įven a 1500VA UPS isn't likely to keep your computer running for more than an hour. I have read and accept the privacy policy and terms and conditions and by submitting my email address I agree to receive the Business IT newsletter and receive special offers on behalf of Business IT, nextmedia and its valued partners. Even if you can get the load down closers to 150 Watts - perhaps enough to run one PC, a monitor and a some networking gear - you'll still be lucky to get more than 10 minutes before the UPS runs flat. By APC's own figures, this UPS can run 300 Watts worth of equipment for around four minutes. 6 to convert the VA rating into Watts rating - so a 1000VA UPS is designed to handle roughly a 600-Watt load.įor a few hundred dollars you'll find an entry-level UPS with a 550VA rating, supporting around a 330 Watt load, such as APC's Back-UPS Pro 550. As a rule of thumb, you should multiply it by. It's a handy idea, but don't expect miracles if you're shopping on a budget.Įvery UPS comes with a "VA rating" (Voltage-Amps) which tells you how much gear you can connect to it and roughly how long it will keep running after the power is cut. Worried about a blackout causing you to lose all your work? A UPS will keep your computer running, but there's something very important you should know.Īn Uninterruptible Power Supply, or UPS, is basically a large battery designed to keep your equipment running should the power go out.
