Hi, I am looking to replace the batteries in my VZ vari -4 mod and the batteries are IMR 18350. I have found replacement rechargeable batteries that are 1200 ma but the ones that came with my mod are 800 ma. What is the difference? Will the 1200 work or only 800? I know where to get the 800 ma ones, but I have found a better price for the 1200.
