Huge Li-Ion Battery

Just thought I'd share this:
http://www.crystalyte.com/lionspec.htm

They have a 3.6V, 10Ah LiIon cell. Its kinda big, (120mm X 42mm), but I bet one of these could run a 1W Luxeon for a while.

Sounds like multiple D cells stack together.

This is 42 mm wide vs 33 mm wide on D's.

The 120 mm height compares to 122 for 2 D's.

This looks like a very interesting cell.

OK I'm a bit confused, listed...
"Li-ion Cell Specs.
Model : 3135A
Normal Capacity 3.6V 10Ah"
But both chargers that are listed are 43.5 volts:

Li-ion Charger Specs:
Input Voltage :AC 85V - 264V
Output Voltage : DC 43.5 +/- 0.5V
Output Current : 1.8A output Currency

And....

NiMH Charger Specs:
Input Voltage :AC 85V - 264V
Output Voltage : DC 43.5 +/- 0.5V
Output Current : 1.8A output Currency.

I would think the chargers are not for singles of this Batt? But multi paks or possibly a whole different battery?
