I had no control over the temperature of the environment. I could control
the charging but I did have to charge them in any temperature.

Yes they ended up being most of the weight of the product. That was
considered OK. If they had more energy per unit volume, it would be
better. Zinc-air would be a lot better from that point of view but they
can't be sealed in use.
