Battery & Charger FAQ

Do you have a question about batteries, chargers, and your electrolarynx or amplifier?
Here are your answers for electrolarynx batteries.
We'll also tell you about your amplifier batteries here. (Scroll down...)

What kind of batteries do your electrolarynx devices use?

The TruTone EMOTE® electrolarynx uses a very safe and proven battery that lasts most people 2-4 weeks between charges, and is very affordable--even lower cost than many 9v batteries. Our legacy devices, such as the TruTone Plus™ Electrolarynx, TruTone® Electrolarynx, and SolaTone® electrolarynx devices, all use 9v batteries. The SolaTone Plus® electrolarynx uses two AA batteries. These are efficient batteries with good life, and you can use either rechargeable or disposable alkaline batteries.

How long will the electrolarynx batteries last?

Our newest device, the TruTone EMOTE® electrolarynx, uses a lithium-ion battery. This is a very safe battery that lasts most people 3-4 weeks between charges. It is rated for 1,000 charges, so it will last many many years. This is a very safe battery design, with a safety circuit built right into it. This is a battery that we have been using since 2011 in our SoniVox Plus® amplifier, and has had excellent reliability. It is a battery chemistry that was designed for longevity and safety.

Our NiMH 9v rechargeable battery is a high quality battery with good life; it will last most people several days, although heavy talkers may require daily charging. If you require longer talk time, choose a TruTone EMOTE® electrolarynx, which typically lasts several weeks.

Battery life is 100% dependent upon speech patterns. Using a lower volume setting will increase battery life greatly. (The last 1/4 turn on the volume doubles the current consumption, but only adds a little bit to the volume.) Heavy talkers will go through the batteries quicker than those who talk very little. Most people can last a 1-4 days on the old fashioned 9v battery. Disposable alkaline batteries typically last 4-7 days.

A typical NiMH rechargeable battery is good for about 100 charges, but often last longer, sometimes several years. Because the high capacity batteries don't need charging as often, they will last longer, if not used until dead. Batteries should be used until a noticeable decrease in volume occurs, then recharged. Draining a battery until it is fully dead may reduce its capacity, and should be avoided.

Do you have a 220v charger or dual voltage charger options for the electrolarynx devices?

Please contact Atos Medical at www.atosmedical.com for a charger in your country. We do not export 9v battery devices, and the other devices use standard USB chargers, which are available everywhere.

Do the TruTone® or SolaTone® electrolarynx models use Servox batteries?

No, they use 9v batteries, but we do carry batteries for the Servox Electrolarynx. We believe the 9v batteries are a better option for electrolarynx devices. The 9v size has high capacity for their size (our High Capacity 9 volt electrolarynx batteries have more capacity than a Servox Battery), and you may purchase 9v batteries at your local drugstore, both rechargeable and disposable.

Amplifier battery & charger questions:

What kind of batteries do the amplifiers use?

The SoniVox® waistband amplifier uses 8 AA batteries. Rechargeable batteries are included.
The SoniVox Plus™ personal amplifier uses an internal lithium battery.
The BoomVox® portable wireless amplifier uses a 9v battery in each of the transmitters. The amplifier itself has a 12v gel-cel battery built in. It may also run on an 12v automobile supply, or 110v AC power. Two disposable 9v alkaline batteries are included for the two transmitters.

Do the amplifiers come with battery chargers?

Yes. The SoniVox® waistband amp includes a constant-current charger which will charge the batteries in about 7-10 hours.
The SoniVox Plus™ personal amp includes a micro-USB charger which will charge the battery in about 3-5 hours.
The BoomVox® wireless amp has a built in charger. This charger will charge the 12v gel cell battery, and trickle charge one 9v battery.
