Query: WARNING These are LR03 1.2V AA @ AAA batteries not HR03 1.5V AA & AAA batteries

You are being forewarned! These are LR03 1.2V batteries not HR03 1.5V batteries. That said most of the products out there require a HR03 1.5V AA batteries rating. What this means is that the LR03 1.2V batteries (which these are) will work but the will not power your electronics to its full potential in addition they will loose power much faster than the HR03 1.5V AA rated batteries. Not all AAA, AA etc batteries are the same in terms of voltage they are only the same in terms of size. Before fore warned and don't get burned like I did!
