Commonly Asked Questions About Batteries and Medical Alert Systems

Our HOME Medical Alert Button battery will last 5-7 years and never needs charging. We get a lot of questions from folks wondering about the batteries that go in the medical alert system. These are important questions as some people have sensitivities to batteries, and the medical alert button is worn close to the body. If we didn't answer all your questions below, please contact Medical Care Alert customer service at 1-877-913-3680 and we'll gladly answer your questions about our medical alert system batteries.

Does Every Medical Alert System Have A Battery?

Yes - in both the medical alert button and in the base station. The medical alert button is powered by a battery that generally never needs servicing - it is self contained and will last several years before needing to be replaced. These buttons are monitored by Medical Care Alert, and we will contact you if we receive a low battery notification from your medical alert pendant. We will replace your pendant with a new one at no charge to you! This way you always know your medical alert button has a strong battery and will be ready when you need it.

Your medical alert console will have an internal battery back up that will kick in if the power goes out. The internal battery will generally last between 24-72 hours depending on which model system you have. If the internal battery ever needs replacing, we will notify you and send a completely new system to you at no charge.

Medical alert equipment is easy to install in your house. All it takes is a wall outlet to plug in the charger and a land line telephone line. You’re furnished with a medical alert bracelet and a pendant. Depending on the type of medical alert system that you have, you might also have a small base console which works as a two-way whole house speakerphone.


A medical alert bracelet is great to have on hand just in case there is an emergency. Just press the button, speak to an EMT/EMD-certified operator and help arrives. Of course, most of the time the medical alert system is sitting quietly, ready at a moment’s notice for when emergency strikes. However, how can you make sure that it will be there for you when you most need it?

How often do you need to test your medical alert device battery?

Test the button on your medical alert bracelet or pendant once a week. First, call the emergency response center from your landline to let them know you’ll be testing. When you press the button and get a response, tell the EMT/EMD-certified operator that you’re testing the system to make sure everything is working correctly.

We continuously monitor your medical alert system and will know if the battery in your medical alert pendant needs replacing. Our customer service team will contact you when the battery is beginning to get low, and make arrangements to send you a new medical alert button with fresh batteries at no charge to you.

How Do I Know If the Medical Alert Button Battery is getting low or needs to be replaced?

We monitor the battery level of your medical alert button. All of our medical alert emergency call buttons are "supervised"; this means they are continuously monitored by our emergency response center. If we ever detect a low battery signal from your emergency call button, our customer service team will contact you and make arrangements to send you a new replacement emergency call button at no cost to you. You never have to worry about it - that's our job!

Is there any fee for pressing the button on the medical alert bracelet?

No way! While some companies who limit or charge a set amount for each push of the button, we’re not among those. The price of pressing the button is included in the cost of the system. Pressing your medical alert button has minimal impact on the battery life.

How long do the batteries in my emergency call button last?

Depending on which system you have, the batteries on the medical alert bracelet and pendant last for up to three years or longer. Some pendants have rechargeable batteries that get swapped out monthly. If you’re worried about the batteries draining (the medical alert system will warn you, and us, if they’re low), then we will be more than happy to replace them for you at no charge.

However, your medical alert emergency call buttons are "supervised" and continuously monitored by our emergency response center. If we ever detect a low battery signal from your emergency call button, our customer service team will contact you and make arrangements to send you a new replacement emergency call button at no cost to you.

What happens to the battery if the power goes out?

The medical alert console and/or mobile device charger is plugged into the wall and has a battery backup. That backup will last for up to 72 hours depending on which model medical alert system you have By that time, the power in your home should be restored and ready to go. Our emergency response center is notified in the event of a power outage and we may contact you if it appears your system is operating only on battery back up power.

Where can you take your medical alert bracelet?

The bracelet and call buttons are waterproof, meaning that you can confidently take them with you anywhere you go. Don’t be afraid to take a shower. Our medical alert system equipment is built to be waterproof.
When you press the button, you will receive immediate service from an EMT/EMD-certified professional who is ready to help. There is always someone there to call in case you have questions or worries about your personal emergency response system, even if there isn’t an emergency right now.

Some companies claim 10 year battery life - is this true?

We think this is highly unlikely. Even a battery that sits on a shelf will lose power over time. We think it's irresponsible of some companies to claim a 10 year battery life, stating it never needs to be charged or replaced, when protecting people's lives and property.

How can they say Life Alert® batteries never need charging?

We are NOT Life Alert® - they are a completely separate company so we cannot speak on their behalf.

It is possible they mean that the end user never has to charge their life alert battery because it is enclosed inside of the life alert pendant and therefore never needs to be charged. In that case, the claim is true and would also apply to our medical alert buttons. The battery in a Medical Care Alert HOME System never needs to be charged and can last up to 7 years before it needs to be replaced.

Just to be clear, there is a difference between a button that requires daily charging, regular routine battery replacement, and a button with a battery that never needs charging. In the last case, the pendant's button alert battery never needs charging but may need to be replaced once the battery gets low.
