Charging batteries I have a spare battery for my Nikon D70s and I got in the habit of leaving it in the (plugged-in) charger. Will this harm it somehow? If I take it out, will it lose its charge?

Hi Colleen Any battery when pluged into a charger will produce heat, in small amounts, in the long run it will shorten it's life. also regardless of if it's a dry cell or acid/alkaloid it will produce gas which escapes from the battery which will also shorten it's life. once the battery is removed from the charger in time it will lose its charge, how soon depends on the type of battery. test it for yourself, give it a full charge then remove it from the charger and mark down the date.

Whoa there Bernard. Slow down a bit. The answer Colleen depends on a number of factors. Some batteries use a trickle charger that continually keep the battery up to full power as long as it remains plugged into the charger. That does not harm the battery and is made specifically for that purpose. As far as I know, dry cells don't emit gas. Gasses are produced by some wet cells. Sealed wet batteries, again as far as I know like the Quantum Turbos and those wet cells used to power Norman 200B or 400, among others, don't leak gasses either. To be sure of what you have and what you should and should not do to prolong the life of both, I highly recommend reading the specific instructions for the power supplies and see what the manufacturer recommends. Take it light ;>)

Mark I see your point relating to a trickle chargers, but notice I said in the long run. but if there a current flowing there will be heat, have you ever noticed the brown and/or gray deposits around a dry cell double A or C battery that was emitted during its life cycle, so then I ask, are they truely dry, and are they truely sealed.the $100 plus Quantum Turbos and wet cells that power Norman 200B/400 serve their purpose well, and I'm sure the convenance of continual charge out weights other options, but 5 to 1 the less time on the charger the longer their life expectancy. I usually dispense tecno gobble, but because I'm old I'm allowed

Well, on this one I should defer to Alan Marcus. Also, I don't know how old you are Bernard, and certainly age is entitled to some degree of deference, but depending on how you look at it, I HAVE been a member much much longer than you have. LOL !!! Latah buddy. ;>) Mark

I have a Nikon D70 and when I first got it I went to class that the Nikon rep gave and he said that it will not hurt the battery to leave it in the charger once charged. I do not have a problem with it sitting in my camera bag either. I will charge it and take it off and 2 months later change my battery and it is still fully charged. It all depends on how much you are using the camera.
