Lithium-Ion batteries are very different from Nickel-Cadmium (Ni-Cd) batteries and must be treated differently. Notebook batteries deliver an extremely high current (similar to a power hand tool) and so the batteries are stressed much more highly than a low-current battery (such as that used in a mobile phone).

If possible, when charging the notebooks at the end of the day, leave the notebus doors open to allow heat to escape. This will only be practical if the notebus can be placed in a secure area of your establishment.
Number each NoteBus bay and number each notebook with the corresponding number. Assign each pupil the same notebook. This will allow you to quickly become aware if any notebook has a problem and also instils a sense of responsibility into the pupils who will hopefully take more care of their 'own' notebook. You can also quickly see if one is missing or damaged and you will know who had it last.

The biggest enemy of the Lithium-Ion battery is heat. You should ensure that when you charge and store your Notebooks or Tablet PCs, they are kept in a cool place with plenty of ventilation. A notebook may get quite hot during use, but is important that the battery itself does not get hot as this will shorten its useful life. Keep the AC adaptor well away from the battery compartment as the AC adaptor can get quite hot.
Always ensure there is adequate ventilation around a notebook and avoid placing them in a confined space when they are charging, unless adequate ventilation can be ensured. This is because the AC adaptors will discharge heat whilst they are on, and this will warm up the air around the notebook battery and thus the notebook battery itself. If you have several notebooks or tablet PCs and their AC adaptors in a confined space, the batteries will be kept warm for long periods of time. In particular, placing the AC adaptor on top of, or in close proximity to, the battery compartment when in use or charging will severely affect the useful battery life and they may only last six months.

If you have another system of the same type that seems to have good battery life, swap over the batteries. If the 'good' system now has a short battery life and the 'bad' system now has a much longer battery life, this indicates that the battery has a problem. However, if the short battery life problem seems to stay with the original system, this indicates that the system may have an incorrect configuration.
