I recently bought a new Vaio laptop which has a 4400 mAh battery. I will use it at home most of the time, and I have an unused uninterruptible power supply (UPS). Should I remove the battery and connect my laptop to UPS? If I do that, how much does it effect the battery's life? I know that batteries stand longer when kept in half-charged in a cool place, but their lifespan decreases in time due to age effect as well.
So is it worth to keep the battery out of my laptop, use a UPS instead and mount it when necessary? or should I continue to work with battery mounted?
1Sure, but the small LI-ion or NiMH battery is much easier to damage over time than the SLA batteries in the UPS. – Ignacio Vazquez-Abrams – 2010-04-16T14:41:19.417
2The point is to extend its life by exposing it to less charging & decharging cycles, and making it not heated. I don't know how much a Vaio battery costs, but I'm sure a UPS is cheaper. – Mehper C. Palavuzlar – 2010-04-16T14:42:44.547
2I disagree. I'd say it would be the same cost (if not cheaper) to replace a battery than a decent UPS. – th3dude – 2010-04-16T14:50:47.313
2the point is moot; he already has the UPS. Better to use the UPS than waste battery life. – RJFalconer – 2010-04-17T13:00:47.350
2I’d leave both, since a power spike/thunderstorm can fry both your laptop’s power supply, the battery and your board. (it happened to me and many of my customers). Make sure you have a decent UPS. Cheap ones rarely really work when they have to. – Martin Marconcini – 2010-06-15T10:23:53.627
