If they last long enough to leak that would suggest the savings using rechargeables would be minimal.
You must have missed my post where I said that I was a bit of a miser, I thought about claiming the eco excuse but honesty is the best policy. As further reason for my opinion the unused maplin AAA batteries I mentioned before that I already had and are still within date appear to be a bit swollen which is a sign of imminent leakage. Have you seen the price of Duracell recently? I may well have to bite the bullet and shop around for a deal on them but for my own amusement and stubborness I will explore alternative methods first.
