ThE ENERgIzINg TRUTh ABOUT BATTERIES…
What is a 7.4 volt Lithium Ion SMART battery?
It is a rechargeable battery common in portable consumer electronics because of its high
energy-to-weight ratios, lack of memory effect, and slow self-discharge when not in use.
Even with recharging, when does this type of battery need to be replaced?
With normal use, the battery industry informs consumers that these batteries have a 30%
degradation per year. With an expected number of charge cycles, our engineers inform us that
after two years of average use, the battery may have to be replaced.
Is the battery ready for use when I receive my chair?
Yes! Most Lithium Ion batteries arrive from the factory 80% charged. It is always recommended
that you allow a battery to discharge completely before recharging.
Are Lithium Batteries safe?
Don’t ask us, ask IBM, Dell, Sony, Toshiba, Apple, Compaq, and all of the notebook manufacturers!
Yes, if used for the purpose intended, these batteries are very safe. Yet it is very important
to remember that these batteries are still sources of power and should not be exposed to
high temperatures (including prolonged direct sunlight), should not be placed in an oven or
microwave, should not be abused or neglected, and should not be opened or modified.
What is the life of the battery and how are these batteries disposed of?
All batteries have a finite life. The life will depend upon how you charge and discharge the
battery and the temperature at which the battery is maintained. According to the Responsible
Energy Corporation, Lithium Ion batteries, like all rechargeable batteries, are recyclable and
should be recycled. They should never be incinerated as they might explode. Most places that
sell rechargeable batteries will accept them for recycling as will TheraForm.
