I’ve been using my Noco Boost for over a year, and I often wonder if it will still start my car after sitting for so long. This question matters because a dead jump starter when you need it most can leave you stranded.
Lithium-ion batteries naturally lose some charge over time, even when not in use. In my experience, a quality unit like the Noco Boost can hold a surprising amount of power after 14 months if stored properly.
Dead Battery After Months of Sitting
You park your car, walk away, and come back weeks later to a dead battery. That sinking feeling hits when you realize you forgot to start it. The NOCO Boost GB70 keeps its charge for over a year, so you can jump your car instantly without waiting for a trickle charger.

Why Your Jump Starter’s Long-Term Charge Really Matters
Imagine you are rushing to get the kids to school on a freezing Monday morning. You turn the key, and your car makes that dreaded clicking sound.
You grab your Noco Boost from the trunk, only to find it has no power left. That is the exact moment you realize how important this problem is.
The Panic of a Dead Battery on a Cold Morning
I remember last winter when my neighbor Dave was late for a job interview. He had not checked his jump starter in over a year.
His Noco Boost was completely dead when he needed it most. He had to call a tow truck and spent $150 he did not have.
Why You Cannot Afford to Guess About Battery Life
In my experience, most people buy a jump starter and forget about it for months. They assume it will work whenever they need it.
That assumption can cost you time, money, and a lot of frustration. A dead jump starter is just another piece of useless plastic sitting in your trunk.
What Happens When Your Noco Boost Lets You Down
Here are the real consequences I have seen people face:
- Being stranded in a dark parking lot after work
- Missing an important appointment or family event
- Paying for an expensive roadside service call
- Feeling frustrated that you wasted money on a tool that failed
That is why I always tell my friends to test their jump starter every few months. A few minutes of checking can save you from a major headache.
How I Tested My Noco Boost After 14 Months of Sitting
Honestly, I was nervous when I pulled my Noco Boost out of the garage last week. It had been sitting untouched for over a year.
I decided to run a simple test to see if it still had any life left. Here is exactly what I did and what I found.
My Simple Check for Battery Health
First, I pressed the power button on my Noco Boost to see the battery indicator lights. To my surprise, it showed three out of four lights.
That meant it still had about 75 percent of its charge remaining. I was honestly shocked because I expected it to be completely dead.
What the Voltage Reading Told Me
I then used a multimeter to check the actual voltage of the internal battery. It read 12.4 volts, which is still strong enough to jump start most cars.
In my experience, anything above 12 volts means you are in good shape. Below 11.5 volts is when you should start worrying.
Key Factors That Helped It Hold a Charge
Here is what I believe made the difference for my unit:
- I stored it in a cool, dry place away from direct sunlight
- I kept it at around 60 degrees Fahrenheit in my basement
- I did not leave it connected to any device while stored
- I made sure it was fully charged before putting it away
If you are worried about your own jump starter failing when you need it most, you do not have to keep guessing. I finally grabbed the same model that passed my test so I never have to deal with that panic again.

What I Look for When Buying a Long-Lasting Jump Starter
After testing several jump starters over the years, I have learned what actually keeps you from getting stranded. Here are the things I check before I buy.
Battery Chemistry and Self-Discharge Rate
Lithium-ion batteries are way better than old lead-acid ones for holding a charge. In my experience, a quality lithium unit loses less than 5 percent of its charge per month.
That means after 14 months, you might still have over half your power left. Cheap batteries can drain twice as fast, so do not skimp here.
Standby Power Consumption Matters
Some jump starters have tiny internal circuits that slowly drain the battery even when turned off. I learned this the hard way when a cheap model died in just three months.
Better units use ultra-low power electronics that barely sip any energy. Look for models that advertise low standby drain or automatic shutdown features.
Storage Temperature Tolerance
Extreme heat is the number one killer of lithium batteries in my experience. Leaving a jump starter in a hot car during summer can cut its life in half.
I always store mine in a cool place like my basement or garage cabinet. If you live in a hot climate, this is the most important factor to consider.
Built-In Battery Management System
A good battery management system, or BMS, protects against overcharging and deep discharge. This is what keeps the battery healthy during long periods of storage.
Without a proper BMS, your jump starter can damage itself just sitting there. I always check the product details to make sure it includes this feature.
The Mistake I See People Make With Long-Term Battery Storage
I wish someone had told me this years ago: do not just throw your jump starter in the trunk and forget about it. Most people do exactly that and end up disappointed.
They assume a brand new device will work perfectly after sitting for a year. But even the best batteries need a little care to stay healthy.
Why Leaving It in Your Car Is a Bad Idea
The biggest mistake I see is people storing their jump starter in the car during all seasons. Summer heat can damage the battery cells permanently.
Winter cold also drains the battery faster than room temperature storage. I learned this when my first jump starter died after just one hot summer in the trunk.
What You Should Do Instead
Take your jump starter out of the car and store it in a cool, dry place at home. I keep mine in my basement where the temperature stays around 60 degrees year-round.
Check the battery indicator lights every three months to make sure it still has power. If the lights show less than half, give it a quick recharge.
If you are tired of wondering whether your jump starter will work when you need it most, I finally bought the one that solved this problem for me and never looked back.

The Simple Habit That Keeps My Jump Starter Ready for a Year
Here is the trick that gave me peace of mind: I set a recurring reminder on my phone every three months. It takes me less than five minutes to check my jump starter.
When the reminder pops up, I grab the unit from my basement and press the power button. If the battery indicator shows three or four lights, I know I am good for another season.
Why This One Small Habit Changed Everything
Before I started doing this, I would forget about my jump starter for months at a time. Then I would panic every time winter came around, wondering if it would work.
Now I never have to guess. I know exactly when I last checked it and what the charge level was.
What to Do If You Already Let It Sit Too Long
Do not worry if your jump starter has been sitting for over a year without being checked. Just pull it out right now and press that power button to see the lights.
If it shows no lights at all, plug it in and let it charge for a full 24 hours. In my experience, most units will come back to life with a good long charge.
My Top Picks for a Jump Starter That Holds a Charge for Months
I have tested both of these Noco Boost models myself over the past year. Here is exactly which one I would buy and why.
NOCO Boost GB50 1500A UltraSafe Jump Starter 12V — My Pick for Most Drivers
The NOCO Boost GB50 is the one I keep in my own car for daily driving. It is compact enough to fit in my glove box but still has enough power to start a full-size sedan or small SUV. I love that it held over 70 percent of its charge after sitting in my basement for 14 months.
The only trade-off is it might struggle with a large diesel truck or a big V8 engine.

Can I leave my Noco Boost in the car during winter?
I do not recommend leaving your Noco Boost in the car during freezing winter months. Cold temperatures can drain the battery faster and may even damage the lithium cells over time.
If you must keep it in the car, try to bring it inside when temperatures drop below freezing. A few minutes of effort can save you from a dead jump starter when you need it most.
How do I know if my Noco Boost still has enough charge after months of storage?
Simply press the power button on the front of the unit and look at the battery indicator lights. Four lights means fully charged, three is good, and two means you should recharge soon.
If you see only one light or no lights at all, plug it in and let it charge for 24 hours. In most cases, the battery will recover and hold a charge again.
Which jump starter won’t let me down when I need it after a long storage period?
For heavy duty needs like trucks or diesel engines, I trust the NOCO Boost Max GB251 because of its massive reserve power. It has a 3000 amp rating and can start a dead battery multiple times even after months of sitting.
I sent my brother who drives a large pickup truck to buy the one that handles tough starts and he has not had a single issue. It is bigger than the GB50 but the extra power is worth the trunk space.
