As for alkaline batteries, they are often used for most kinds of batteries, and watch batteries are no exception. They have a shorter shelf life compared to silver oxide batteries, but they still last pretty long regardless. They are cheaper to make (hence the smaller cost), the only problem with alkaline watch cells would be that they could potentially leak and could cause corrosion and damage your watch (or other devices that use these batteries. Miniature zinc-air batteries are button cells that use oxygen in air as a reactant and have very high capacity for their size. Each cell needs around 1cm 3 of air per minute at a 10mA discharge rate. These cells are commonly used in hearing aids. A sealing tab keeps air out of the cell in storage; a few weeks after breaking the seal the electrolyte will dry out and the battery becomes unusable, regardless of use.

While these batteries are not identical, they are very similar in size and voltage and can be used interchangeably in many devices.

These types are associated with legacy applications, such as for vacuum tube equipment (A, B, and Cbatteries), or are no longer manufactured. A motorcycle battery is a ‘live’ product, that is to say, once it has been commissioned, it is giving off energy, discharging. A by-product of this process is sulphation, so if you don’t keep your battery charged (either by riding the bike or using a battery charger), it will eventually get to a stage where the sulphation causes a short-circuit and you won’t be able to start your bike - or recover your battery. You could try a motorcycle battery charger with a reconditioning mode or just buy a new battery. this is a lithium battery. The handbook is wrong!
