This is why they are sometimes called the most environmentally friendly battery type. NiMH batteries tend to have a higher capacity than NiCads and suffer far less from the memory effect. ...

| nib |
A fountain pen is a writing instrument, more specifically a pen, that contains a reservoir of liquid ink composed primarily of water. The ink is held in the reservoir by air pressure until needed, at which time it is fed to a nib through a "feed" via a combination of gravity and capillary action. Refilling ink either involves replacing an ink cartridge, filling the pen with an eyedropper, or using one of a variety of internal mechanisms to suck ink from a bottle. ...
