Sure. I even stated the difference in voltages and current capabilities in my post. I was simply responding to your comment that "you shouldn't notice any performance difference with alkaline batteries compared to lithiums". You will notice a BIG performance difference. This is BECAUSE lithiums (either primary or rechargeables) operate at higher voltages (not always) and have higher current capacities (always) than alkalines. If lithiums had the exact same voltage as alkalines and the exact same current capabilities as alkalines, they would perform exactly the same as alkalines (ignoring cold weather performance and total runtime differences).
