According to the technology team, this is an old problem that occurred when there were mercury batteries in the market. Since July 2011, Energizer is now only using mercury-free batteries. Many cameras used the mercury chemistry for a stable voltage output for metering. Energizer does not make a battery that is a suitable replacement for this application. Unfortunately, we need to recommend that you contact the camera manufacturer for a suggestion on a fix.

In what type of device are you wanting to use this battery? This battery has a 1.5 V open circuit voltage (nominal). We aren't aware of any batteries in this size that would give you 1.35 V.

Unfortunately, we are unaware of any battery called the SR26W. With that said, we have seen the 397 watch battery referred to as the 26 battery by other manufacturers. While distribution may vary from store to store, our records indicate that Walgreens carries the Energizer 397 battery.

Thank you for this great question, I would be happy to assist you. I would recommend calling our consumer affairs office so we may gather a bit more information on this product to better assist you.
