Does the Button Battery Charge?

Dec. 10, 2020

Coin cell batteries are a common type of battery that we use every day. Coin cell batteries are often seen in cameras, watches, calculators, toys, etc. They are widely used due to their small footprint, lightweight, long-lasting power supply, and convenience. They are widely used due to their small footprint, lightweight, long-lasting power supply, and ease of use.

However, many times, we use it and then throw it away after use. And do not pay attention to, some kinds of coin cell batteries can be recharged and put into use again. In order to effectively avoid this use of coin cell batteries waste, as well as reduce environmental pollution, then how do we identify the coin cell batteries? Coin cell battery suppliers explain to you.

Coin cell battery type features

1.Alkaline coin cell battery

Good discharge effect, relatively expensive, nominal capacity 15mAh~140mAh. 15mAh~140mAh nominal capacity, mostly used in electronic toys, hearing aids, lighters, watches, and so on.

2.Zinc oxide silver button battery

The best of the button battery. Capacity is higher than carbon, alkaline coin cell batteries. Good voltage stability. (90% part of the charge, the voltage is stable above 1.45V; after 10% of the charge, rapid linear discharge down.) This battery is leak-proof and suitable for long-lasting use. They are used in hearing aids, cameras, watches, calculators, and other places.

Also, for coin cell batteries that use "zinc electrodes" - such as alkaline batteries, silver oxide batteries, zinc-air batteries, etc. Due to the manufacturing process, they may contain mercury. Due to the manufacturing process, they may contain mercury. Therefore, it is also important to observe whether the battery case is marked with a mercury content label.

TWS Coin Cell Batteries

Coin cell batteries, classified by primary or secondary charge ability.

1.Primary batteries

There are LR alkaline batteries (1.5V), SR silver oxide batteries (3V), ZA zinc-air batteries (1.4 V), CR lithium primary batteries (3 V), and so on.

2. Secondary batteries

LIR secondary battery (3.7 V), Ni-MH battery, Ni-Cd battery, etc.

The use of coin cell batteries depends on the actual situation, choose the battery type suitable for the corresponding environmental characteristics. Try to choose mercury-free coin cell batteries; recycle them reasonably and do not throw them away to avoid environmental pollution. Primary batteries and rechargeable batteries should be distinguished and used in a reasonable manner.
