How to maintain your BOOKOO H9 jump starter

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 BOOKOO H9 Car Battery Jumper
• Proper charging is crucial to maintain the functionality of your BOOKOO H9 car battery jumper.
• Storage. Proper storage is equally important, especially if you don’t use your BOOKOO H9 frequently.
• Regularly testing your jump starter ensures that it’s in working condition when you need it.
• Whenever possible, store your BOOKOO H9 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
