A range of CR2016 batteries from leading brands including our own trusted brand RS Pro. CR2016 batteries are 3V lithium batteries which are used in devices such as watches, car keys and electronic toys.
Due to their size, button batteries are used for smaller electronic devices. Standard domestic applications include watches, scales, remote controls and calculators. They can be found in greeting cards and are used to power small LEDs or speakers within the card. Coin batteries can also be used to power medical devices such as hearing aids, implantable defibrillators and pacemakers.
Lithium and silver oxide coin batteries have stable voltage throughout their lifespan. Unlike alkaline batteries, they are subject to a drop in voltage quite suddenly as they approach end of life. They are more resistant to corrosion and have better leakage resistance. The main difference between silver oxide and lithium batteries is the voltage. Lithium batteries provide voltage of 3 V while silver oxide batteries offer 1.5 V.
