I find the 14500's wear out really fast requiring frequent battery changes after about 10-15 dives. I prefer to use the Energizer Lithium non-rechargeable cells for in place of SAFT. I get about 5-6 months (50 dives) in my Petrel2 Ext computers with the Energizers.
I've given up on the SAFT cells due to their flakyness and history of bootleg batteries in the market.
