What is needed is a true scientific head to head test during 2008. The new homologated NiMH cells Versus the latest Lithium Polymer offerings. Personally I dont think they (LiIon Polymer) should be allowed unless the products:
(1) Contain cells which carry UL1642 recognition
(2) Have on board protection circuit for over voltage (over charge) and under voltage (over discrage).
(3) Are hard cased in at least 1.50mm of UL94V-0 plastic.
This would make them 'proper' products, not cells linked together and which rely on the user to (i) balance them (ii) correctly set their charger so they dont dangerously over charge them (iii) Ruin them by over discharging them.
If you were asked to do these things with your laptop battery you would laugh!
