Since "FP" aren't a real world unit, there is no generic rule on how to convert from watt seconds to FP. Therefore that's basically a factor of how much of a discount you're getting from your Accessability - the bigger the discount, the less-efficient your conversion rate is going to be.
GURPS Magic Technology college spells use the conversion of 1 kilowatt-hour = 10 energy (360 kilowatt-seconds or 360 kilojoules = 1 FP). That's a pretty harsh ratio if you're looking to eat 9V batteries like popcorn - a 9V battery has ~0.00007 kilowatt-hours...
A 6V lantern battery (the chunky big square ones) are better, with 0.003 kilowatt-hours, but that's still only 10.8 kilowatt-seconds. You'd need
34 to regain
1 FP/ER. At about $9 each online, that's ~$306 (plus tax) and 50 lbs per FP, which as a Trigger probably counts as Expensive (or at least a big pain), and thus -20%, if you're going for 1/minute Regeneration.
I pulled up a premium car battery at $180 with exactly 360 watt-seconds, which is more affordable, but just about as heavy.
