I have been using LiFe (a123s and others) for the last 5 years. I use them on everything. Fuel pump Air compressor,Blower, even my dustbuster. I tried to blow one up early on just to see what happened. The only thing that happened was the cap popped off the can. The other reason is that they hold a charge for a very long time (very low self discharge rate) and with a top off are ready to go quickly
