One of the most popular hearing aid batteries brands, Rayovac has a strong reputation for both reliability and value. The size 13 hearing aid battery is most commonly used in slightly larger behind the ear and in the ear devices that deliver greater levels of amplification and usually offer telecoil connectivity.
Delivery was satisfactory, no complaints. I just found the product expensive, (size 10 batteries, 7 packs of 6 ). When the postage was added, the batteries worked out at over E1 per battery. Usually on-line shopping is the cheaper option.
