| p.1 #18 · Canon 1D Mark II N Replacement Battery? |
So - I bought Lenmars last year, and they are good if I shoot my 1D2n often enough & I'm cycling them.
If I don't, they go totally flat in about 10 days of sitting in the camera. Is this normal?
Can I leave a Lenmar on the 1D2n charger or is it bad to do that?
I don't think that frequent "topping up" is a good idea with any NiMH battery. I've read it can cause "charge depression" which means they (at least temporarily) lose capacity. Better to let them run down and then do a complete charge cycle. They do lose charge over time just sitting in the camera, but 10 days seems extreme. I do a "refresh cycle" on any battery that has been unused for a month or more, which supposedly helps maintain their capacity.
