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.

Battery rehab

I think they should have a date sticker on the unit to know when it was rehab.

I had both of my Snap-On CTB4185 batteries rebuilt, and they are like new again. Hopefully, they last as long as the originals. The process was easy, the price was great, and the shipping was quick. They look better than when they were new !!!

Better than new

I have my batteries rebuild a few months ago. I use the high performance service and it work amazing. They say that it is the same as Snap-On but I think it run for longer in my impact. I saved much money on this process and will be come back for more services.
