Frequently Asked Questions
Following Q&A will teach you everything you wanted to know about batteries and how to optimize the usage.
My appliance doesn’t work as long as it did with the original batteries. Why not?

Can Ni-MH batteries be used for lights with a wire filament in them?
Yes, Ni-MH rechargeable batteries can be used for (torch) lights with a wire filament.
Where can I find more details about Panasonic’s latest promotions?

What should I do when my rechargeable batteries heat up when I’m using them?
Whereas some heat is normal, unusually hot batteries could be caused by over-discharging or short-circuiting. In such case, remove them from the device immediately.
What are the best hearing aid batteries?
Battery performance greatly depends on the device and on the conditions.
When should I recharge my batteries?
In general it’s best to never let your batteries deplete completely. Try to recharge them before the energy level drops below 30%.
Why is a used coin battery thicker than a brand new one?
Whereas some size change is perfectly normal, it should not be overly pronounced. If so, replace the battery immediately. A bulging coin battery may lead to device malfunction and even short-circuiting.
When should I remove the batteries from my device?
Always remove batteries from devices you don’t use for longer periods, from devices connected to AC power and when batteries are empty.
Is there any other battery which can be used for hearing aid instead of zinc air battery?
Panasonic zinc air batteries have been specifically designed for hearing aids, other batteries may not perform as well.
Do I need to use the same type of battery in one device?
Any minor difference in the batteries will cause either batteries to overcompensate and to deplete faster.
