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.
kind of batteries do your electrolarynx devices use?
Plus(tm) Electrolarynx, TruTone(r)
Electrolarynx, and SolaTone(r)
electrolarynx devices all use 9v batteries. The SolaTone
Plus(r) electrolarynx uses two AA battieres. These are
efficient batteries with good life, and you can use either rechargeable
or disposable alkaline batteries.
is a "High Capacity" 9v battery for the electrolarynx speech aid?
The standard 9v rechargeable battery is between 150 and
160mAh. The High Capacity speech aid battery is 260 to 300mAh; this
means the talking time is nearly double that of the standard battery.
Note, we have periodically substituted high capacity batteries when the
standard batteries were not available. This means you may have gotten
more than we promised. It does not mean a replacement battery is "no
good," but rather, you were given a free upgrade and we just did not
long will the electrolarynx batteries last?
Battery life is 100% dependant 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 1-3
days on the regular 160mAh battery, and 2-3 days or more with the high
capacity 260mAh battery. Frank Smith of CT once saved a high capacity
battery just for anti-smoking lectures at schools--he did 32 one-hour
lectures on one charge! Disposable alkaline batteries typically last
A typical 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 noticable decrease in
volume occurs, then recharged. Draining a battery until it is fully
dead may reduce its capacity, and should be avoided.
you have a 220v charger or dual voltage charger options for the
All three chargers are available in 110/220v dual voltages.
Please select the 110/220v option in the drop-down box on the product
catalog page before you click Buy Now, or specify this need in the
order comments, because we include a standard 110v-only transformer
without this request. AT this time, all of our chargers come with 110v
US plugs; even with the 220v option, you may need an adaptor.
is the difference between the charger options for the electrolarynx
The trickle charger is just a 2-place 9v constant current
charger. It can charge one or two batteries at a time, and is fine for
slow-charging lower capacity batteries up to 180mAh. This charger can
not charge the higher capacity batteries, such as the 250mAh that come
with the upgraded chargers. Batteries should not be left on it for over
20-24 hours max. The dual-voltage trickle charger has a switch that
must be turned to select 110 or 220v. The other two chargers
automatically select it.
The Rapid charger can charge one or two 9v batteries in about
an hour or two. This is a small wall-plug charger, convenient for
travel, but due to the fast charge, the batteries will wear out
slightly faster. Batteries should not be stored on it.
the TruTone® or SolaTone® electrolarynx models use Servox
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.
battery & charger questions:
kind of batteries do the amplifiers use?
The SoniVox(r) waistband amplifier uses 8 AA batteries.
Rechargeable batteries are included.
The SoniVox Plus(tm) personal amplifier uses an internal lithium
The BoomVox(r) 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.
the amplifiers come with battery chargers?
Yes. The SoniVox(r) waistband amp includes a constant-current
charger which will charge the batteries in about 7-10 hours.
The SoniVox Plus(tm) personal amp includes a micro-USB charger which
will charge the battery in about 3-5 hours.
The BoomVox(r) wireless amp has a built in charger. This charger will
charge the 12v gel cell battery, and trickle charge one 9v battery.
