electric toothbrush without a battery
I've tried several electric toothbrushes but I'm tired of all the battery issues. After a while they all fade and don't hold much of a charge and don't run at full speed.
So . . . are there any electric toothbrushes that are corded (no batteries)?
The closest I've seen are those polishers in the dental office (somewhat similar to this)

That sounds safe.
You need a lithium ion battery powered toothbrush.
Lithium ion last a lot longer and do not have the same aging characteristics.

I have a Braun NIMH toothbrush. It's lasted a long time.

I have one of those cheapy $8 Oral B battery powered tooth brushes similar to the Crest Spin Brush. Been using it for years and has served me well.

Sonicare Elite- Best electric toothbrush, IMHO. Costs a bit more than others but I've had mine going on 4 years now, operating without a single problem. It even holds a charge over a couple of days so no need to take the charger when I'm out for a few days on business trips.

I have a SoniCare that has lasted me a few years now and the battery hasn't died on me.

Sonicare makes the best toothbrushes. I've been using the same one with original battery for at least 7 years, and it's showed no signs of getting weaker.

Have been using a Sonicare for 2-3 years now with no battery issues thus far.

Electric toothbrushes that use AA batteries are worthless. You may as well just use a regular toothbrush.

Just buy an oralb or sonicare or whatever from costco. When the battery doesn't last, take it back.

I have one that you just shake to recharge. I just go ahead and put toothpaste on it and stick it in my mouth while I shake to charge it. By the time I'm done charging it, my teeth are clean.

Stop charging it every night. Problem solved. Charging a battery that is already charged destroys their lifespan.
You should only plug in your toothbrush base once a week, if that.

Ah, yeah, that could be the problem. I leave mine off the base until it starts to slow, then recharge fully.

I have a cybersonic. I've had it for two years. I use it several days to a week in a row without recharging, then plug it in and let it charge back up. It never seems to run out of juice that way.

Have you considered a manual toothbrush?

I'm going to make an electric toothbrush that is powered by one of those little hand-cranked generators.
I will sell it at Eddie Bower and Brookstone for $20 each as a "green" item and make a shit-load of money.
It will be glorious.

Isn't that only going to be the case if it's a lousy charging circuit?
I've seen some "chargers" that were little more than a resistor and a diode. And then there are chargers that continuously monitor the state of charge, and only give it what it can safely handle. These are usually not cheap though.

I use a Crest model, uses 2 AA batteries. I use rechargeable ones in it and it lasts for weeks between charges. Never timed it, but i'd say I recharge about once a month. Wish you could change the heads on em, I just dip it in bleach now and then and buy a new one a couple times a year. cheap enough

This is not true but the opposite for Li-on batteries. The deeper the discharge, the fewer cycles you get. The "happy medium" for them is around 40% charge but since keeping a battery right around that is almost impossible, it is better just to keep it charged than to let it completely discharge (and of course Li-On batteries have extensive circuitry to keep them from being too deeply discharged, which can make the battery very unsafe).
