Are you talking about a Li-ion battery? I cannot imagine that there is any problem leaving a Li-ion battery in the camera the whole time..

Perhaps the manual is referring to non-rechargeable batteries.Chris R..

Or, perhaps they are referring to leaving the battery in the camera for extended periods when the camera is not in use, i.e. when you plan to store it for, say, six months...

Read somewhere - Canon manual??? - that leaving the battery in, but not using the camera for an extended period (few weeks), shortens the overall life of the battery and/or drains it faster..

Would you care to quote us the exact words. (You do not say what model so I have no means of doing that)..

What type of battery?.

Unless it is a most unusual type, which I doubt, what the manual says is nonsense. Leaving bateries in and the camera on - that would be different..

The danger of leaving a battery in a camera when stored is that the battery may leak. This will damage the camera..

Since you do not indicate which camera you have let me say that on some, if not all, DSLR cameras there are two batteries. One is removable and the other is not. The non-removable battery in the D200 requires 72 hours to charge once the removable battery is put in the camera. This assumes a long period of time with the removable battery removed and the nonremovable battery is drained..

As mentioned, alkaline batteries can leak, but rechargeables are at risk too..

Pretty much all cameras continue to use a very small amount of power even when the camera is turned off (date/time for example)..

Leaving the batteries (LiIon or NiMH) in for a short period (one or two weeks), in most cases, will not be a problem, but if you store the camera for an extended period of time (months or longer), then the battery could be drawn down to the point where it becomes completely flat and it could go into a condition of reverse polarity..

At this point the battery may be permanently damaged. So do not leave batteries in the camera for prolonged periods..

Here's a quote from the Canon manual for the 300D.

Note the quote is referring to the "Canon Battery Pack BP-511 or BP-512" - ie. the main battery..

"If the battery is left in the camera for a prolonged period without the camera being used, a low electrical current may be discharged excessively and the battery's service life may be affected.".

And from the Canon 400D manual:.

"If the battery is left in the camera for a prolonged period, a small amount of power current is released, resulting in excess discharge and shorter battery life...".

Good Day,Roonal.
