Frequently Asked Questions

Following Q&A will teach you everything you wanted to know about batteries and how to optimize the usage.
They do. We guarantuee performance for up to three years after production. After this we cannot guarantee the battery will perform as well as it’s supposed to.
Cycle life is the number of times the rechargeable battery can be recharged.
Panasonic strongly advocates not attempting to charge primary batteries such as alkaline, zinc carbon, or lithium, using Ni-MH chargers. Alkaline batteries are not designed for recharging, and doing so could cause leakage and in the worst case lead to the batteries exploding.
Please seek medical attention immediately. While serious accidents are relatively uncommon, swallowing a coin battery may still cause burns or breathing difficulties.
Immediately head to the nearest emergency room. Avoid drinking or eating before a doctor has provided a decent diagnosis.
By recycling your batteries, you actively help reduce landfill waste. Up to 90% of the materials in Panasonic batteries can be reused to make new batteries or processed in other industries.
Assuming your device isn’t faulty, causes may lie in either improper contact with the terminal or in the batteries themselves.
No. All Panasonic rechargeable batteries come pre-charged. However, due to changes in conditions and temperature during transportation, some discharge may have occurred - meaning the battery may not be at full capacity when you take them out of the package.
The smart charge function on chargers checks the charging conditions of the batteries, the temperatures of both the batteries and the charger, etc. This allows the charger to individually charge each battery under the best conditions. This function shortens the charging time by 5% compared to the chargers without such function.
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.
