Charging information

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..

Work great

We just ordered 50pc of these and also the other style with the harness and couldn't be happier. In the past, we found some cheaper replacements but they never seemed to hold up to normal use. The MTO replacements are holding a better charge and have already outlasted the others that we tried.

Perfect fit

Battery fits and works great

Great Product

We tried these and some other "aftermarket" batteries. The MTO rebuilds are far more aesthetically appealing and from a functionality standpoint, they outperform the competition by about 20%. This is the best bang for your buck that you can find today.

Great 0090041000 battery at a reasonable price. I had bought some other aftermarket 0090041000 batteries elsewhere and they did not look nor work as good as these do. MTO Battery is the cream of the crop!


Fit my Trilithic 860DP perfectly!
