Do “Ultra” or “Advanced Formula” alkaline batteries last any longer than standard alkalines?
Yes, for high drain applications Duracell Ultra and Energizer Advanced Formula batteries do last longer than standard alkalines. Unfortunately, they only last about 30% longer. So instead of lasting for say 15-25 images they might last for 20-40. That’s a little better but it’s still pretty poor, especially considering that these new style alkalines cost as much as $1.50 each. Rechargeable NIMH or NiCds are the better choice for high drain applications. They last much longer on a single charge and don’t have to be discarded after a single use. There are a couple of cases where their actual voltage difference may be important to you. In the case of a device like a radio, where a higher voltage can mean a stronger signal, a fresh alkaline battery may be more desirable – but more expensive – than a rechargeable NiMH battery. This is also true for a flashlight, which will be brighter with the initial higher voltage of alkaline cells. This minor difference may not be important to you and is
