I have a Panasonic FZ8 camera and the battery pack being used with it is now 3 years old and showing good signs of getting weaker. So I have procured a replacement which is also from Panasonic. The new one has a mAh value of 695. The old one has 710 mAh. I read some general information on this and I came to know that higher the value of mAh, the longer it will hold the charge. So my question is, will this difference of 15 mAh be significant? The old one used to give me around 200 shots when it was newer and it is now going down before 100. I have not started using the new one yet. Any insight on this will help.
I should be regular ratio and proportion. 695/710= 97.887%, so the new battery should provide about 98% of the old batteries shots, i.e. about 4 shots less. mAh is the number of milliamps usable times the number of hours of use. 1000 mA is 1 amp, so yours can go an hour using up about 0.7amps. The more flashes the more amps, the less number of pictures. Sort like water in liters per minute, the bigger the flood gate, the less time.
