Understanding Silver Oxide Batteries

Understanding Silver Oxide Batteries

Most batteries in the miniature battery product line are silver oxide / zinc alkaline batteries. They’re generally used in applications like calculators, watches, hearing aids, electronic instruments, and photoelectric exposure devices. The general characteristics you can expect include:

• A higher voltage compared to mercury batteries

• Flatter discharge curve compared to alkaline manganese dioxide batteries

• Great for use in low temperatures

• Excellent resistance to vibration, acceleration, and shock

• Low constant internal resistance

• Incredible service maintenance – more than 90% after five years of storage at 70 degrees

• Come in a variety of voltage sizes from 1.5 – 6 volts

• Available in numerous battery sizes

The construction of silver oxide 1.55v batteries is generally flat circular cathodes with homogeneous gelled anodes. Separators of specially selected materials help prevent the materials from migrating of any solid particles in the battery. Nylon is generally the insulating and sealing gasket material, and the exterior battery is most often nickel, which helps prevent corrosion and ensures good electrical conduction. Most China LR (cheap alkaline versions) with a model such as LR626 often have no (as in zero) quality control and are made with unknown chemical formulations; these must be avoided and not used in a watch because silver oxide batteries provide non-declining power output; they start at 1.55v and expire at 1.55v with little voltage drop that could affect a timepiece accurately operating.

One of the reasons silver oxide batteries are chosen over others is that provide excellent performance at extreme temperatures. For example, they can be used at temps of up to 131 degrees Fahrenheit. They can also work at extremely low temperatures – up to -20 degrees Fahrenheit. Note that though they will work at these temperatures, there may be some loss in performance at these extremes.

Another reason they’re chosen for small electronics like watches and hearing aids is because they are great in low drain, continuous use situations. They can last up to five years when in use – a huge advancement compared to similar batteries available just a few years ago.
