Factors Affecting NOCO Jump Starter Recharge Time
The time it takes to fully recharge your NOCO jump starter isn’t fixed — it depends on several important factors. Knowing these can help you manage expectations and keep your jump starter ready when you need it.
Battery Capacity and Model
NOCO jump starters come in various sizes, from compact units like the GB40 to heavy-duty models like the GB150. Larger batteries naturally take longer to recharge because they hold more power. For example, a GB40’s smaller battery may recharge in about 3 hours, while the GB150 might take closer to 5 hours.
Charger Output
The amperage of your charger affects recharge speed. Using the original charger supplied with your NOCO device ensures optimal charging time. Lower output chargers or USB chargers typically slow down the process, sometimes doubling the charge time.
Battery Condition and Usage
If your jump starter’s battery has been heavily used or not maintained properly, it may take longer to charge. Over time, lithium-ion batteries gradually lose capacity and recharge efficiency.
Temperature and Environment
Extreme cold or heat can impact how fast your battery recharges. Charging in a cool, dry environment is best. Very cold temperatures slow down chemical reactions inside the battery, extending recharge time.
Charger and Cable Quality
Using damaged or low-quality cables can reduce charging efficiency or cause intermittent charging, increasing the total time needed.
Tips to Speed Up the Recharge Process for Your NOCO Jump Starter
While you can’t drastically cut the charging time beyond what the manufacturer designs, there are smart ways to ensure your NOCO jump starter charges as efficiently and quickly as possible:
Use the Original Charger
Always use the charger and cables that came with your NOCO jump starter. They are optimized to deliver the correct voltage and current needed for safe, fast charging.
Charge from a Stable Power Source
Plug your charger into a reliable wall outlet. Avoid charging from USB ports on computers or car USB chargers, as these usually provide lower power and extend charge times.
Keep the Jump Starter Cool
Charge your device in a cool, dry area. Excess heat can slow charging and damage battery cells over time. Avoid direct sunlight or very warm places.
Disconnect After Full Charge
Once the jump starter shows it’s fully charged, unplug it promptly. Although NOCO chargers have maintenance modes, continuous charging isn’t ideal for long-term battery health.
Charge Regularly
Even if you don’t use your jump starter often, recharge it every 3 months. Keeping the battery at a good charge level helps maintain its efficiency and shortens the time needed when you really need it.
How to Know When Your NOCO Jump Starter is Fully Charged
Knowing when your NOCO jump starter is fully charged helps avoid unnecessary downtime and extends your device’s battery life. Fortunately, NOCO makes this simple with built-in indicators.
Here’s how to tell when it’s fully charged:
LED Battery Indicator Lights
Most NOCO jump starters feature a row of LED lights. As it charges, these lights progressively illuminate.
• When all lights are solid (not blinking), the device is fully charged.
• A blinking light usually indicates ongoing charging at that level.
Charge Status Light (100%)
In many models like the GB40 and GB70, a white LED light labeled 100% turns solid when the battery reaches full charge. This is your clearest sign.
Charging Time Estimate
Although not a direct indicator, knowing your model’s expected charge time helps:
• GB40 – ~3 hours
• GB70 – ~4.5 hours
• GB150 – ~5–6 hours
Power Button Behavior
On some models, pressing the power button during charging will show the current charge level via the LED lights.
