How long do the batteries last before needing replacement?
A longevity of 15 years is given by the manufacturer, A123, for high current usage such as power tools or electric vehicles. Our low current use should ensure an even longer lifetime.
How long do the batteries last before needing a re-charge?
Because the battery is now only powering the clocks, a charge should last for about 3 days or more of continuous play BUT the batteries are only being used when the unit is turned on.
Do these batteries need a special handling/charging regimen like other batteries?
No, these batteries do not suffer from memory effects like others & don't need to be drained fully & then re-charged. They can be used straight away without any special consideration.
Will they explode or catch fire if I overcharge them?
No, but they will die like all batteries! I had a user who unknowingly was using a battery charger putting out 7.2V to charge them (my 2 batteries are in parallel & so only need a max 3.6V charge). The batteries survived for a while before finally dying. They didn't catch fire or emit any noxious fumes - simply overheated & died. On examination one battery endcap had partially come off the end of the battery (it still measured 3.2V).
Will it damage the batteries if I deeply deplete them?
No, but it's not a recommended practise. The manufacturers recommend that they are not deeply depleted (<2.7V) in high current situations as this effects their longevity. In our low current usage this is less of a worry, possibly not a worry at all but I still recommend to avoid this!
What happens if the batteries run out during listening?
The sound will simply stop, maybe crackle a little bit first. There is no voltage spike or loud sound that will cause damage to your speakers or ears!
