Battery Information

Proper battery care helps to preserve the life of your laptop battery, ensuring your laptop is ready to power up when you need it. This is important regardless of whether your laptop is brand new, a few years old or second use.

When you use your computer for the first time, connect your laptop to an electrical outlet using the supplied AC adapter until the battery is fully charged. If you have a new battery you should allow for full discharge 3-4 times to allow for synchronisation to the laptop.

To gain a true read on each battery’s capacity, as per industry standards, we test the battery under the power setting ‘Maximise My Battery Duration’. Our benchmark is 80% capacity and above. Once we have run our tests, we revert back to the default BIOS setting, ‘Maximise My Battery Health’.

The setting, ‘Maximise My Battery Duration’, is an eco-mode. It allows the battery to last as long as possible between charges. The default setting, ‘Maximise My Battery Health’, maximises battery health by lowering the maximum battery charge level to 80%. This is more akin to using sports mode in a car, so it will drain the battery quicker than in ‘Maximise My Battery Duration’ mode.

If you selected to have your Circular Computing™ laptop fitted with a brand new battery, please read these instructions so that you gain the maximum life from your new battery.

Your new battery is shipped in a partially discharged state and every li-ion laptop battery needs to be ‘run in’. To do this, just repeat a full charge and discharge 3-4 times. It is normal for the battery meter on the laptop to be incorrect at first. This is because the battery meter is still calibrated to the condition of the old battery.

After you have completed several full charge and discharge cycles, the battery meter will re-calibrate to the new battery.

Please be aware that until your Circular Computing™ laptop is calibrated to your new battery the laptop may cut off prematurely without warning. It is, therefore, important to save your data frequently.

It is common for a new battery not charge to 100% straight away. This does not mean the battery is faulty - simply turn off the laptop then remove and re-insert the battery and connect to the AC power. The battery should then continue to charge.

Never completely drain your battery by repeatedly turning your laptop back on after it has shut down due to low battery power.

Doing this will mean that the safety circuit inside your battery pack may lose power and the safety switch may permanently disable the battery.

1. Once run in, avoid frequent full discharges because this puts additional strain on your battery. It is better for your battery to only partially discharge it several times and recharge it frequently (rather than one full discharge). Recharging a partially charged lithium-ion battery does not cause harm because there is no memory. Short battery life in a laptop is mainly caused by heat rather than charge / discharge patterns.

2. Your laptops battery meter should be calibrated by applying a deliberate full discharge and recharge once every 30 charges. If ignored, the battery meter will become increasingly less accurate and in some cases turn off the laptop prematurely.

3. Keep the lithium-ion battery cool and avoid keeping it in a hot vehicle. For prolonged storage, keep your battery at 40% charge and store for no longer than 30 days without using it. Failure to follow this instruction may result in your battery not being able to be recharged.

• Lithium-ion batteries can rupture, ignite, or explode when exposed to high temperatures (60°C/140°F), or direct sunlight. They should not be stored in a car during hot weather.

• Short-circuiting a Li-ion battery can cause it to overheat, ignite or explode.

• Never open or puncture a Li-ion battery’s casing. Li-ion batteries contain safety devices that protect the cells inside from abuse. If damaged, these can also cause the battery to overheat, ignite or explode.

• Never expose the battery to water or liquid.

• Never dispose of in fire or water.

• Never dispose of the battery in your normal trash. Please follow your local laws as to the proper disposal.

The Microsoft Windows battery meter icon is shown in the system tray (on the task bar) and links to your battery information.  

If you cannot see your battery icon in the system tray, you can add the icon back following these instructions:

Original fully tested batteries are supplied with a 90-day warranty. Any new battery options are supplied exclusively under license from high quality suppliers and come with a full 12-month warranty. 

The battery operating time (i.e., the amount of time the battery can hold a charge) will decrease over time. Depending on how often the battery is used and the conditions under which it is used, you may need to purchase a new battery during the life of your computer. 

The battery operating time will depend on the battery type and how you use your laptop - it is significantly reduced when you perform operations including using optical drives, wireless devices and external devices. 

Running the computer in maximum performance mode will drain the battery faster and using high brightness display levels or power-intensive software (such as 3D gaming, video rendering etc) will also reduce battery operating time. 

To extend the battery operating time, run your laptop in balanced or power saving modes. 

To change your power-saving settings, type Power in the Windows Start Menu search box and select Power & sleep settings.
