Following Q&A will teach you everything you wanted to know about batteries and how to optimize the usage.

Panasonic EVOLTA NEO is your best choice for high-drain devices. Thanks to more precise manufacturing, increased density and silver compounds, the battery will greatly outperform other batteries.
While most batteries will still work in extreme temperatures (albeit with shorter lifespans), Panasonic EVOLTA NEO is your best choice for extreme cold or warm weather.
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.

Assuming your device isn’t faulty, causes may lie in either improper contact with the terminal or in the batteries themselves.
Operating times may vary depending on the conditions in which you use your hearing aid. The most common cause is not letting it breathe after you take off the seal. Ensure at least 60 seconds of air flow before inserting it into the hearing aid.
For best performance, always try to keep the battery’s energy level above 30% of its total capacity. Also: always use batteries of the same type and expiry date together.
In general, appliances are designed to match the characteristics of dry batteries and to work within the voltage range of 1.5V to 0.9V. Thanks to this characteristic, Ni-MH rechargeable batteries can be used in appliances which require alkaline batteries, even with lower initial voltage. 
No. Do not use batteries in water or in vacuum conditions - this will cause them to rust and short-circuit.
