Quick Question again:
Can we use Ebay brand batterys for the ARIZER AIR and use a different charger to charge the batteries? Has anyone done this? I have the same size batterys in my laser pointer thats why i ask, and a spare charger.
You could read all 127 pages and you will find lots of information.
If you want to avoid voiding your warranty and want to be a safe as possible only use the Arizer recommended batteries. I think the consensus is that the charger is not so "sensitive", worst case a bad charger will damage a battery but can't really damage the Air.
If you do want to risk using different batteries (remember voids warranty, is not advised) make sure that they are unprotected (no nipple for the plus), can be discharged at 5A and preferably have the safety standard UL 1642.
I am using Sony VTC4/5 and NCR18650B batteries and am pleased with the results. Watch out there are lots of fakes out there! I am only using these batteries because I already had them. If I had to buy new ones I would just takes the safe and easy route and buy the Arizer ones.
