How long does a lithium rechargerable camera battery general last before replacement?

Is there any way to find out if the battery is begining to fail?How long does a lithium rechargerable camera battery general last before replacement?Modern Lithium Poly cells %26quot;last%26quot; for about 300-500 charges. But %26quot;last%26quot; is defined to be the point at which a full charge only hits 80% of the original charge. So it may be even a bit longer before you notice it.



Older Li-ion cells actually handle more charges, maybe as many as 1,000 full charge-discharge cycles. But they also age independently of the use, dropping between 5% and 20% of total capacity every year, depending on how they're kept (temperatures, charged or discharged, etc).



End of life/failure is really more of a judgment call than a specific event, since, aside from drastic failure (damage or defect), they just get progressively worse. But it happens slow enough you may not notice, unless you're comparing an older cell against a new one. If you start to notice the battery just seems to die sooner than it once did, it's probably about time to think about a replacement.



One thing to watch... Li-ion and Li-poly cells can be damaged by draining them too far. What happens is that a secondary battery more or less forms in the contact area of the cell and starts to kill the contact. So while you really want to fully discharge NiCAD and NiMh cells for the best performance, you shouldn't let a Lithium cell die completely. Most Li powered devices are smart enough to prevent this level of discharge, but particularly if it's an expensive battery, it doesn't hurt to watch out for it.How long does a lithium rechargerable camera battery general last before replacement?no way really, lithium ions last for an incredibly long time, 5 years or more probably. I'd be very surprised to have to replace a 3 year old one.How long does a lithium rechargerable camera battery general last before replacement?I have an old D100 that uses Li-ion batteries. I have had over 5 years and they are still performing perfectly. Just take good care of them and charge them just before you take your camera out for a shoot.How long does a lithium rechargerable camera battery general last before replacement?They're all different, but mine claim 300-500 shots like someone mentioned. It varies because people use the battery to transfer images, view videos, do slideshows from the camera, delete pics, etc.
