It shows blue in the picture but it is more a blue-green colour.

I'd picked up a 'new' 12 cell pack for less than $10 - so I thought 'How can I go wrong'. They are supposed to be 2400ma but I now think the no name pack manufacturer overstated the capacity. The charge to 4.2 V OK and hold voltage but measure only 1800mah approx on hobby charger.
Note to self: If the pack isn't branded, leave it alone unless it's free.
