How to Maintain Your YESPER YJS15
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 YESPER YJS15 Car Battery Jumper
- Proper charging is crucial to maintain the functionality of your YESPER YJS15 car battery jumper.
- Storage. Proper storage is equally important, especially if you don’t use your YESPER YJS15 frequently.
- Regularly testing your jump starter ensures that it’s in working condition when you need it.
- Whenever possible, store your YESPER YJS15 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

AJ –★★★★☆ (4/5)
Convenient
Super compact. My husband works in a shop and has been able to start two cars at a time, but after that, it needs recharging. Overall, this is still a great deal for emergencies situations.
