I'm no expert but I've soldered directly onto batteries for years and never 
had any problems.

I use a soldering station and run it up to 850 degrees (F).

I start by tinning the battery then using my finger rub spit on it to cool 
it, people afraid to be crude can use a damp sponge.

After I've tinned all of the battery ends I then can quickly tack wires onto 
them running the soldering station at arount 750 degrees (F).

I run the temperature up high to reduce time spent applying heat to the 
battery.
