Charging Recommendations

1. Always ensure that the battery is not hot and is at room temperature before charging.

2. Once charged, remove the battery from the charger. Do not store the battery on the charger for extended periods of time. Please note that storing a battery in a charger that is not plugged into the wall, can potentially cause the battery to drain back into the charger. This was more common with older chargers and we have also noted it in some newer chargers.

3. It is recommended to not store the battery on the device when not in use. Storing the battery separately removes the possibility of the device slowly draining the battery. 

4. If you have not used the battery for 2-3 months, we would recommend recharging the battery and if possible, use them. This helps maintain their health.

5. Lastly, be sure to store your battery in a dry environment. If possible, avoid temperatures below freezing and above 110F to maximize battery life.

Coolest Cooler secret weapon!

My kickstarter Coolest Cooler was great until the batteries for the blender died and could not be replaced. I found MTO after a quick search. They are awesome. The communication is excellent and what a fast turnaround. I am talking a week. My batteries came back charged and ready to go. Thank You!

Rebuild of Coolest Cooler Battery

I thought my Coolest Cooler Battery was trash after it wouldn’t take a charge any longer. Then I found MTO on the internet. Shipped it off to them and had a BETTER battery back from them in 2 weeks. Thanks for the great service!!

New rebuilt battery better than original

I had thought I would never be able to use my Coolest cooler again inasmuch as the company has disappeared. I was searching for a replacement battery when MTO appeared in my search. I read about their service and decided to take a chance. Thank you for rebuilding my Coolest battery and improving it! Now my Coolest cooler does everything it did when new, only a little better.
