Default 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.

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.

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).
