3 and one half years ago I bought an E cig called "smok Woo", It came with 4 ICR 16340 3.7V 650 mAh batts and the device only used two at a time...This let you have 2 fresh batts all of the time...Well, now they don't hold there charge very well and I went to Ebay to buy so new ones...I found some batteries of the exact specs BUT also found some with 1100mAh and some with 2300mAh...My question is will these work ?....Are they better or not?....Thanks for any advice
