Understanding Rechargeable Hearing Aid Batteries
Rechargeable batteries have become an increasingly popular option for powering modern hearing aids. They offer convenience and environmental benefits compared to traditional disposable batteries that must be frequently replaced. This article provides an in-depth guide to the top rechargeable hearing aid battery systems available.
Benefits of Rechargeable Hearing Aid Batteries
Here are some of the main advantages of using rechargeable batteries for hearing aids:
- Greater convenience not having to routinely replace batteries
- Cost savings over time compared to disposable batteries
- Environmental benefit with less battery waste
- Improved reliability with steady power delivery
- Hands-free charging options in many newer models
However, rechargeable batteries arent necessarily right for everyone. They require an upfront investment and diligent charging habits. For those open to adapting their routine though, most users find the switch worthwhile.
Overview of Rechargeable Hearing Aid Battery Systems
There are two main types of rechargeable battery technologies used in todays hearing aids:
Lithium-Ion Batteries
Lithium-ion batteries have high energy density making them well-suited for compact hearing aids. They tend to last over 5 years on average. Lithium-ion batteries need frequent recharging though, often overnight while sleeping.
Nickel Metal Hydride Batteries
Nickel metal hydride batteries withstand more charging cycles before needing replacement compared to lithium-ion. However, they have lower energy density resulting in shorter runtimes per charge. NiMH batteries also experience gradual demise in capacity over time.
Most hearing professionals recommend lithium-ion batteries for their superior longevity and consistent power delivery. However nickel metal hydride remains a cost-effective option for some.
How to Charge Rechargeable Hearing Aid Batteries
Recharging hearing aid batteries is simple. Most battery charging stations plug into a wall outlet. You set your hearing aids inside the charger overnight, with an indicator light letting you know when charging is complete. This allows hearing aids to conveniently repower while you sleep.
Tips for Charging Rechargeable Batteries
- Aim to recharge batteries every night
- Avoid extreme hot or cold during charging
- Dont interrupt the charge cycle too early
- Top off with occasional full dischargesmonthly
Todays rechargeable batteries are designed to withstand frequent charging without impacting lifespan or performance when following usage guidelines.
Indicators Its Time to Replace Rechargeable Batteries
Plan on replacing rechargeable hearing aid batteries every 3-5 years when you notice:
- Reduced runtime per charge
- Frequent power outages
- Oversensitivity to temperature
- Damage like cracks or leaks
A hearing care professional can assess battery performance and determine when replacement is appropriate based on your usage.

Considerations When Selecting Rechargeable Hearing Aid Batteries
With many rechargeable battery options for hearing aids now available, its important to weigh your needs and priorities. Here are 7 key considerations as you compare systems:
1. Battery Life
Runtime between charges varies. Lithium-ion batteries generally last 18-30 hours per charge. NiMH drained faster at 12-18 hours. This determines charging frequency.
2. Charging Time
Most rechargeable hearing aid batteries fully replenish in under 3 hours, but overnight charging is easiest for maintaining power. Ensure the charger fits your lifestyle.
3. Cost
Upfront cost is higher for rechargeable battery hearing aid models but they save money long-term without frequent disposable battery purchases.
4. Wireless Connectivity
Many rechargeable batteries allow adjustments via smartphone apps for ease of use. Not all have wireless capabilities though so consider functionality needs.
5. Water & Dust Resistance
Determine required water and dust protection ratings based on your lifestyle and environments. This ensures batteries withstand use cases.
6. Hearing Aid Styles Supported
Rechargeable battery solutions differ in hearing aid models supported, from RICs to ITCs to CICs. Select options matching your fit needs.
7. Charger Size & Portability
Charging cases range from compact, portable versions to larger multi-functioning desktop styles. Pick whats convenient for travel habits or bedside use.
Getting Helped By a Hearing Care Professional
With many rechargeable battery options now available for hearing aids, the buying process can feel overwhelming. Thats why it helps turning to a hearing care professional for guidance.
Experts like audiologists can evaluate hearing loss, lifestyle needs, and usage requirements. They fit rechargeable solutions suited to your budget and needs for the best hearing possible.
Hearing professionals also provide ongoing support for rechargeable battery care and maintenance. They handle replacements when runtime declines or other issues emerge so you can focus simply on recharging at night.
In a world filled with choices, sometimes it just helps turning to an expert for recommendations. Seek out a hearing care professional for personalized advice regarding rechargeable batteries suitable for your hearing aids.
FAQs
How long do rechargeable hearing aid batteries last?
Rechargeable batteries last 3-5 years on average before needing replacement. Lithium-ion batteries maintain capacity better over time than nickel metal hydride. Runtime per charge starts out over 24 hours but declines with heavy use.
Can you mix rechargeable and disposable batteries?
It is not recommended. Rechargeable batteries operate at lower voltages than disposable zinc-air batteries. Mixing these could damage hearing aid electronics over time or cause operational issues.
Do rechargeable batteries lose capacity over time?
Yes, rechargeable batteries will show reduced runtimes per charge over years of repeated use. More significant capacity loss occurs with nickel metal hydride batteries compared to lithium-ion versions after hundreds of cycles.
What are signs my rechargeable batteries need replacing?
Indications your rechargeable hearing aid batteries need replacing after 3-5 years of use include: shorter runtime per charge, frequent unwanted powering down of hearing aids, temperature sensitivities, damage like cracks or leaks, and error alerts.
