Most mobile computers come with only a single battery. The reason for this is that when two batteries are used, the computer needs to have built-in circuitry and the extra casing for both batteries. This increases the weight and also makes control more complicated.
Despite this, we have made the leap to a dual-battery system with the CF-C1. By making it hot swappable, which means being able to change a battery without having to turn the power off, we are able to achieve very long running times. So long, in fact, that you can actually use the CF-C1 all day long while keeping the power on the whole time. With a typical notebook PC, when the battery needs to be replaced, you have to power down the PC, change the battery, and reboot. During this time, the PC is not useable. This short time loss, however, could be detrimental for people such as pharmaceutical sales reps.
In their effort to persuade doctors to adopt the drugs and equipment sold by their company, these sales reps usually spend long hours waiting for doctors to finish consulting or other business. A doctor will eventually emerge from the examination room only to disappear again. This short time is the opportunity to make eye-catching presentations of relevant information about a medical product and explain its merits. In this situation, where "two hours wait per two minutes of presentation" is the norm, the ability to instantly take advantage of even the smallest opportunity is decisive. Once a busy doctor has been stopped, he or she will get irritated if asked to wait for the computer, even if it is only to wake from sleep mode. It is essential to have the computer running all the time, always available to seize the moment. Running out of power would be unthinkable. Naturally, it is also out of the question to take time out to power down and replace the battery.
Now, with the CF-C1, equipped with two high-capacity battery packs installed in parallel, you can be always ready. Besides having impressive long-running specifications, if one of the batteries runs low, there is no need to switch off the computer, you can simply replace it with a fresh battery while the computer is running. This hot-swap capability means that the replacement battery is recognized without the need to reboot the system, and extended running time is possible.
If you want to keep the computer running all day through, all you need is a few spare battery packs. Using a battery charger, you can keep the spares fully charged and take them with you. In places where mains power cannot be used, this reserve power can make all the difference.
