Paul: The BN utilizes Nickel Metal Hydrite batteries, which develop little, or no, memory. They have several advantages over the Lithium Ion technology in this application. The Lithium Ion, LI, batteries are smaller in size, but considerably more expensive. LI batteries need replacing after about a year, Nickel Metal Hydrite, NIMH, are good for over 2 years. These figures equate to 350 charges for LI, vs over 700 for NIMH. There are also some operating parameters reguarding temperature that are quite favorable to NIMH technology. FYI, all rechargible batteries beed to be recharged, they can't sit idle.
I hope these facts have shed some light on rechargible batteries for you, the good news is that they are rechargible, & not the older Nickel Cadnium technology, that definitely develops memory!!
