It’s green!
As battery technology advances, the focus is on mercury free batteries.
More and more countries are now legally required to use mercury free batteries, and the number is growing yearly. Mercury Free technology is State of the Art and the only battery fulfilling the new IEC Standard defined for streaming HI’s. A key parameter in the IEC Standard is 15 minutes non-stop Streaming. During this 15 min a very high current is drawn from the battery. If the battery is not specifically made for this purpose there is a high risk that the hearing aid will stop working or work intermittently.
The running time for Mercury Free and Standard batteries is equal when used within the same category of hearing instruments. Mercury Free cells are also more environmentally friendly because there is no mercury added to the cell.
The Mercury Free cells are developed for new requirements of hearing aids with wireless functionality.
Note: Be aware that for hearing instruments with wireless functions, battery life in general is shorter than it would be with a non-wireless hearing instrument. This is independent of battery composition (Mercury Free or Standard Zinc Air).
Yes.
Zinc Air hearing aid batteries use air as an energy source, and the tab seals the air holes on the battery. Once the tab is removed, it takes approximately two minutes before the hearing aid battery is activated/charged. At that point, the battery compartment can be closed. If not the battery could potentially become damaged and will not come back to normal Voltage level needed!
Please remember not to remove the tab before the hearing aid battery is to be used. Reattaching the tab will not prolong the running time of the battery.
Our batteries have a minimum “shelf-life” of two years. However, this estimate cannot be guaranteed if the batteries were previously stored incorrectly.
Optimal room storage temperature for storing hearing aid batteries is between 10 and 25°C. Heat may shorten the running time and a humid environment is not suitable for storage. Finally, avoid storing hearing aid batteries in the refrigerator.
Contact with metal objects such as keys or coins can cause a hearing aid battery to short-circuit, therefore it is recommended to never carry individual batteries loose in a purse, wallet or handbag.
Hearing aid batteries, whether they are used or new, must be stored out of the reach of small children and pets to prevent them from swallowing a battery. If batteries are ingested, seek medical help immediately.
Please make sure you protect the hearing aid battery air holes from moisture. Switching off your hearing aid when not in use will also prolong the life of the battery. If the battery should get wet due to sweating or anything else, dry it!
An important factor for longer battery life and greater power is the quality and design of the electrodes. The number and size (diameter) of the air holes also have an influence on the power of the battery.
Zinc Air button cell batteries are classified as non-hazardous waste.However, it is recommended to bring the batteries to the common local collecting points for batteries - to make sure they can be recycled.
There could be several reasons for this. Here are some things to check:
lf the hearing aid does not work properly after replacing with a new battery (wait two minutes after removing the tab before use), please take your hearing aid to your hearing care provider for further troubleshooting.
If the discharged battery is left in the hearing aid after the end of its life, humidity can influence the battery chemistry and lead to swelling, especially in extreme weather conditions such as a tropical environment. Once a battery is at the end of its life, it should be removed from the hearing aid.
Statistics show that, in most cases, the reasons for a short running time are not necessarily production faults, but rather:
Improper handling can also reduce the running time of the hearing aid battery, e.g.:
The rechargeable hearing aid cells are available in the sizes p10accu, p13accu, p312accu and p675accu.
They can be used in most hearing aids of the relevant size. To charge the ACCU plus cells, several power one charging solutions can be used.
These fast chargeable batteries are ecologically sound. By using our rechargeable button cells, you help to protect the environment. The rechargeable batteries do not contain any heavy metals like mercury, cadmium or lead.
These high-performance NiHM batteries are characterized by their excellent reliability and quality without any memory effect. All power one batteries are made in Ellwangen/Germany and are subjected to strict safety and quality checks.
Please ensure that the surfaces of the power one ACCU plus and inside the appliance are kept clean. For best results and product life, always avoid deep discharging or short circuiting the battery. The batteries should be stored at a room temperature of 20-25 degrees without their product life being affected.
Charging in inferior charging devices without a battery charge indicator and shut-off function
can harm your batteries or impact the capacity of the cell. We therefore recommend using our power one charging solutions.
Physically determined rechargeable hearing aid batteries (NiMH-technology) have a lower energy density compared with zinc air hearing aid batteries (primary cells). This is expressed through a lower capacity, which is consistent with just approx. 1/10 of the capacity of primary cells. In exchange the rechargeable hearing aid cells are able to be recharged approx. 500 times.
In rechargeable hearing aid devices, the ACCU capacity is sufficient for one day. The same model hearing aid device which uses zinc air batteries should have at least 10 days running time.
No. A new rechargeable battery reaches its full capacity after several charge-/discharge cycles.
The recommended temperature range for charging and storage is at room temperature (20–25 degrees).
Yes. Even in a passive state a low current circulates, which can cause deep discharge after a longer time. Deep discharge can harm the battery and lead to an irreversible loss of capacity.
