How to Maintain Your GBX45
If you own a portable jump starter or are considering getting one, it’s crucial to understand how to keep it in top-notch condition
- Regular Inspection for Optimal Performance of Your GBX45 Car Battery Jumper
- Proper charging is crucial to maintain the functionality of your NOCO GBX45 car battery jumper.
- Storage. Proper storage is equally important, especially if you don’t use your GBX45 frequently.
- Regularly testing your jump starter ensures that it’s in working condition when you need it.
- Whenever possible, store your GBX45 portable jump starter in a moderate temperature environment between 50 ºF – 70 ºF. Like vehicle batteries, exposure to extreme temperatures is detrimental to jump starter batteries, both in the short term and long term.
- Respect the cycles. Every jump starter is subject to a duty cycle in which the vehicle can be cranked only so long before a period of rest is needed. For almost all jump starters, the recommended duty cycle is between 5-6 seconds of cracking followed by 3-5 minutes of rest.
- Clean clamps. A battery in poor condition may have battery acid on the posts, so wiping down the clamps after jump starting a vehicle always is a good practice to keep the clamps from becoming corroded

Great Performance, but Bulky
This jump starter is a lifesaver. It jump-starts my SUV without breaking a sweat. The safety features are excellent. My only gripe is that it’s quite bulky, making it a bit cumbersome to carry around. Still, it’s worth it for the peace of mind.
