Yes John. From the Green Car Congress site, this information is about the new battery pack for the 2006 Civic hybrid.

“The battery pack stores electricity in a bank of Nickel Metal-Hydride cells. This bank of 132 1.2-volt units stores up to 158 volts of electrical energy for the IMA motor compared to 144 in previous versions. A new Panasonic dual module casing reduces weight from previous hybrid battery packs and also allows it to increase efficiency of the electrical flow. The battery pack is also 12% smaller in volume than the prior.”
Although I could not find the reference, :? I believe I read that the cells were a different size, and mechanically more rugged than the previous design.
