Frequently Asked Questions

Following Q&A will teach you everything you wanted to know about batteries and how to optimize the usage.
Change the batteries as soon as the device starts malfunctioning. Remove the batteries if you plan on not using the device for a longer period of time.
In general it’s best to never let your batteries deplete completely. Try to recharge them before the energy level drops below 30%.
Batteries in smart keys usually last between 1 to 2 years. Unusually short battery life may be caused by electromagnetic interference. Avoid keeping your smart key near other electronic devices such as phones, laptops and other screens.
Coin batteries have a low voltage (1.5 V) and a diameter less than 12 mm to prevent any serious accident. Also, packaging has been designed specifically to prevent accidental ingestion. Panasonic coin batteries are thus relatively safe and serious accidents are very uncommon.
Turn off the device and remove the battery immediately. Remove the remaining leakage using a cotton swab. Avoid skin contact at all times.
Battery performance greatly depends on the device and on the conditions.
While leakage is rare, it may still occur if the battery is used incorrectly. Leakage is usually caused by leaving the battery in an unused device or short-circuiting.
Please seek medical attention immediately. While serious accidents are relatively uncommon, swallowing a coin battery may still cause burns or breathing difficulties.
Never apply heat to batteries. Keep them away from any heat sources like heaters, candles, stoves and fires. Exposing them to too much heat could cause them to tear, leak or even explode.
Typically for an alkaline battery is a gradually decreasing voltage when it discharges, which means that for some appliances, which need a high base voltage to operate, the appliance stops working even while the battery has still a bit of energy left.
