Yep, you got it. Horrible memories of fitting those with freezing fingers.
Spec chart is on pages "57" and "58" of the catalog - on page "58", towards the right hand side is a column titled Batterytorchflux Today, 02:34 AM
Sorry, but where do you read this? Spec chart only tells output, runtime and more of that. No mention of battery usage.
Edit: I should scroll
