Button cell batteries have a higher energy density and a longer shelf life, which is one of the biggest reasons for their immense popularity. These are good all-around batteries for everyday electronic devices.
These batteries can withstand a long time on shelves and still maintain their capacity! But for it to be true, one must get these batteries from a reliable source. I am assuming this is exactly what you are asking.
So here are some of the reliable names in the industry to source
wholesale button cell batteries for low prices
As the leading button cell batteries wholesaler in China,TDRFORCE GROUP, established in 1999, calling for “Green Power For Life”, is dedicated to the manufacturing, development, research, design and export of high quality batteries at affordable prices.
Button cell use in RTC modules as power source
Button cells are used to power small portable electronics devices such as wrist watches and pocket calculators. Wider variants are usually called coin cells. Devices using button cells are usually designed around a cell giving a long service life, typically well over a year in continuous use in a wristwatch. Most button cells have low self-discharge, holding their charge for a long time if not used. Relatively high-power devices such as hearing aids may use a zinc–air battery, which has a much higher capacity for a given size, but dries out after a few weeks even if not used.
Button cells are single cells, usually disposable primary cells. Common anode materials are zinc or lithium. Common cathode materials are manganese dioxide, silver oxide, carbon monofluoride, cupric oxide or oxygen from the air. Mercuric oxide button cells were formerly common, but are no longer available due to the toxicity and environmental effects of mercury.
Button batteries (or cells) do not contain lithium but for instance alkaline and have a 1,5 Volt output. They are generally a bit smaller than coin batteries, for instance the popular LR44 alkaline battery is 11,6*5,4 mm.
The LR44 battery is an Alkaline Zinc Manganese button cell battery. The LR44 battery is typically a 1.5 Volt with an operating temperature ranging from 0°C- 60°C, while optimal temperature is 20°C.
Button batteries are made from a variety of chemistries, including silver oxide, alkaline, lithium, and zinc air. Not to mention, that some button and coin cells are rechargeable, so depending on the product, a rechargeable battery may be the best choice for you.

Attention: Button cells are dangerous for small children, as when swallowed they can cause severe internal burns and significant injury or death.TDRFORCE has attempted to mitigate this by adding a bitter coating to their batteries.
