Charging Recommendations

Always ensure that charging is done while you are present, on non-flammable impermeable surface such as concrete or steel, with adequate ventilation, and with proper fire extinguishing equipment nearby.

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.

Don't wait any longer. Send your BAT101 battery pack to us for repair today!

Note: When we are rebuilding your battery, if your circuit board is found to be defective, we will contact you. At that time we will provide you with the option of sending us another battery or we can refund you for the rebuild service. The old cells are removed and recycled prior to circuit board testing and cannot be shipped back to you. 

Additional information regarding these battery packs and recommendations for their care can be found here.

Orders containing lithium batteries will ship by ground only regardless of the shipping method chosen. If you desire shipping insurance on the shipment from us back to you, please click here to add it.

Battery Rebuild

I was very impressed with the process, I phoned to have the process explained due to me living in Canada. The person I talked was very helpful. The time it took from shipping to MTO, the rebuild and then shipping back to me was very quick. I would recommend this service to anyone needing batteries restored. Thank you.

Works Great!

I just tried out the blender with the new upgraded battery using the large homemade ice from the trays. Worked way better than before. For MTO's team. It was a fast turnaround less than 2 weeks. I sent another battery for repair. Thank you MTO.
