How to Maintain Your BuTure BR300
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 BR300 Car Battery Jumper
- Proper charging is crucial to maintain the functionality of your Buture BR300 car battery jumper.
- Storage. Proper storage is equally important, especially if you don’t use your BR300 frequently.
- Regularly testing your jump starter ensures that it’s in working condition when you need it.
- Whenever possible, store your BuTure BR300 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

Lisa C.- ★★★★★ (5/5)
Jumper cable!
These are a perfect solution to jumping anything without the hassle of using two vehicles. They are small and economical. Would recommend a must have especially for women. I used them three times before I had to fully charge them again on 8 cylinders vehicles.

Bought this car jump starter for emergencies and to have the relief of being able to start my car with ease at any moment without needing help from anyone! Highly recommend to have with you for traveling, camping, for festivals when your car is just sitting all weekend long, or to help others in need! Great price to feel safe – five stars from me!

This item arrived just in time! I was able to use it to start my car to go to the store and get a new battery! Using all the features, I see it is a great value at the price. It held charge much longer than I expected, and recharges quickly.
