If you or a loved one has undergone Deep Brain Stimulation (DBS), you may wonder, how long does a DBS battery last? DBS is a treatment that helps manage symptoms of conditions like Parkinson’s disease, essential tremor, and dystonia. The device used in DBS relies on a battery to send electrical signals to the brain, helping to improve movement and reduce symptoms.
The battery life of a DBS device varies depending on different factors, including the type of battery, stimulation settings, and usage. Understanding how long your DBS battery will last and knowing when it needs replacement is important for uninterrupted symptom management. In this article, we’ll explore everything you need to know about DBS battery life, when to replace it, and how to extend its lifespan.
Understanding DBS Battery Life
The battery in a DBS system powers the implanted device that delivers electrical impulses to the brain. There are two main types of DBS batteries:
1. Non-Rechargeable (Primary Cell) Batteries
- These batteries usually last 3 to 5 years before they need replacement.
- Once the battery runs out, a minor surgical procedure is required to replace it.
- Many patients choose this option if they prefer not to worry about regular charging.
2. Rechargeable Batteries
- These can last up to 15 years with regular charging.
- Patients need to charge the battery daily or every few days, depending on the settings.
- Rechargeable batteries reduce the frequency of replacement surgery but require consistent maintenance.
The choice between rechargeable and non-rechargeable batteries depends on individual needs and lifestyle. Your doctor will help you decide which option is best for you.
Factors That Affect DBS Battery Longevity
Several factors influence how long a DBS battery will last, including:
- Stimulation Settings – Higher settings use more power, which can drain the battery faster.
- Frequency of Use – If the device is on for longer periods, the battery will run out sooner.
- Device Manufacturer – Different brands (Medtronic, Abbott, Boston Scientific) have slight variations in battery life.
- Patient’s Condition – Some conditions may require stronger stimulation, which affects battery usage.
Keeping these factors in mind can help you plan for battery maintenance and replacement when needed.
Signs You May Need a DBS Battery Replacement
It’s important to recognize when your DBS battery is running low. Here are some common signs:
✔️ Worsening Symptoms – If tremors, stiffness, or other symptoms return, the battery may be low.
✔️ Unusual Sensations – Some patients report feeling different sensations when the battery starts to deplete.
✔️ Battery Alerts – Some DBS devices have alerts or indicators that notify you when the battery is running low.
✔️ Doctor’s Assessment – Regular check-ups can help track battery life before it runs out completely.
If you notice any of these signs, contact your doctor to discuss the next steps.
DBS Battery Replacement: What to Expect
If your DBS battery needs to be replaced, here’s what typically happens:
🔹 Doctor Evaluation – Your doctor will check your device and confirm that the battery needs replacement.
🔹 Battery Replacement Procedure – The old battery is removed, and a new one is implanted.
🔹 Recovery – Most patients go home the same day or the next day. Some mild discomfort is expected, but recovery is usually smooth.
🔹 Device Adjustment – After replacement, the DBS settings may need to be adjusted for optimal performance.
The procedure is straightforward, and patients often feel relief knowing their device will continue to function properly
How to Extend the Life of Your DBS Battery
While DBS batteries will eventually need to be replaced, you can take steps to make them last longer:
✔️ Use the Lowest Effective Stimulation Setting – Higher settings drain the battery faster. Your doctor can help find the best balance.
✔️ Regular Check-Ups – Routine visits help monitor battery levels and make small adjustments that can improve battery life.
✔️ Consider Rechargeable Batteries – If you want to reduce the need for frequent replacement surgeries, a rechargeable DBS system may be a good option.
✔️ Charge Rechargeable Batteries Consistently – If you have a rechargeable system, keeping it charged regularly helps maintain its lifespan.
Taking care of your DBS device can help it last longer and ensure you get the best symptom control.
