I was wondering how I should charge my electric toothbrush to get the longest life out of the rechargeable batteries. The toothbrush uses 2 Nicad AA rechargeable batteries and the batteries are trickle charged. The manual suggest that I keep the handle in the charger all the time, and says that there is no way that the batteries can be overcharged. I currently keep the handle on the charger, and completely discharge the handle every month or so. Should I be doing it differently? Cheetah Designs asked
In our home we have this problem. The toothbrush. It doesn’t have anywhere to sit.
Our pedestal sink doesn’t have enough space and we aren’t quite ready to tackle a bathroom renovation (especially based on our toothbrush needs) just yet.
So out of curiosity, we left our charging station in the linen closet to see just how long 1 full charging would last on the toothbrush. Without the base getting in the way we were able to put the toothbrush in our medicine cabinet for easy use.
Each day we pulled our toothbrush from the cabinet to use it. When we were finished we returned it back to it’s home behind the mirrored door and made sure to brush at night as well. Each cycle in the toothbrush is 3 minutes, so the toothbrush was being used for roughly 6 minutes each day.
We started our little experiment back over the 4th of July weekend where we charged our brushes (both my husband and I use one) before heading out to the family farm in Nebraska for the weekend. The little light up meter on the brush dropped a bar before the weekend was up, and the second bar after another two weeks. But it held onto it’s last little bar of “time left to brush” until yesterday the 15th of October. So 3 months and a handful of days.
In the past we had always charged them once they got down to their last bar. Back on the charger they went and everything went along as normal. Now we know that we don’t have to bother with the inconvenience of propping the charger on the sink (or in some cases in the sink bowl… which was dry no worries) we will be keeping up with using the charging base a little as possible, which is most likely more healthy for the battery and the charging memory that it keeps.
Now we are curious if there is anything else we do the same experiment on!
