LSD NiMH cells that provide reasonable capacity even in subfreezing temperatures
Without a datasheet, nothing is certain. But Sanyo do seem to be masters of the art and tend to lead the field in LSD NiMH. Their claim for a 1500/2000 cycle lifetime (eneloop / eneloop lite) and 75% retention at 3 years is superior to anything else I've seen so far. They also claim operation at down to -20 °C. No curve shown but liable to be acceptable given -10 °C curve. 

So, I'd expect that you may well get inferior performance from other brands &mdash; especially from those who provide no datasheets.
