How to prolong nikon en-el9 battery life ?

Don't mix old and new nikon en-el9 batteries when you use them. The new ones will be stronger and can cause the older ones to leak battery acid.
Cut down on programs running in the background. Itunes, Desktop Search, etc. All these add to the CPU load and cut down nikon en-el9 battery life.
Cut down external devices – USB devices (including your mouse) & WiFi drain down your nikon en-el9 laptop battery. Remove or shut them down when not in use.
Prevent the Memory Effect - If you’re using a very old laptop, you’ll want to prevent the ‘memory effect’ – Keep the nikon en-el9 battery healthy by fully charging and then fully discharging it at least once every two to three weeks. Exceptions to the rule are Li-Ion batteries (which most laptops have) which do not suffer from the memory effect.
