I have not used or recharged my krups bio care 570 toothbrush in a long time. I am not getting any charge after charging for several hours. The light does not go on but the base feels warm. Is this dead or will it eventually charge?

SOURCE: My shaver doesn't stay charged very long

The motor is fine, what happens is that the internal battery loses the ability to fully charge and run the motor for a long period of time. While you "could" change the battery out with a newer one using solder, it's unlikely that it would cost less than buying a newer model at the store or from ebay. The average life of good shavers made a few years ago was about 3-5 years due to the type of batteries in it. I used mine with a charging cord for a while but that became an issue once while traveling. I bought a new one.

SOURCE: Trimmer Not Charging - No CHARGE Light too.

I had the same problem, I suggest that you go to your local WAL-MART and return it. Just tell them you want to exchange with a different one and forgot the receipt. This works because I did it with my Remington MB 300 Beard Trimmer.

SOURCE: Braun 5614 rechargeable cordless shaver light flickers

Your batteries are starting to degrade, but the good news is they're still holding a charge for a week, so you really don't need to rush to replace them at this point.

The flickering of the charged indicator is normal, as the shaver is still plugged in and the batteries are fully charged. The flickering is due to the batteries chemicals breaking down, and as such, the charge cycle keeps "topping" them off while it's still plugged in.

When you finally aren't able to get a decent amount of cordless operation and run times from your shaver, then you'll want to get them replaced, whether you decide to do that yourself or have it done by a professional service center, is up to you.

Here's a reference for your future use. www.electricshaver.com carries replacement (factory OEM) batteries for most brands of shavers and they also will provide the repair/replacement service for you, should you decide you don't want to do it yourself. You can also give them a call at 1-888-476-1785 and request a price quote, etc.

Anyway, your shaver is working fine and all you need to do is make sure you're not letting the shaver stay plugged in and charging constantly for more than a day, since any "extra" chargind isn't doing anything except keeping the batteries at a constant state of charge. Heat is a byproduct of charging and discharging any battery and as such, you want to allow for a cool down period before recharging them.

I tend to use my shaver until it is almost completely discharged before recharging it. By doing this, you can get the longest working life out of your batteries before you'll have to replace them.

Hope you find this Very Helpful and best regards!

Lithium ION batteries are usually rechargeable. The use mode for these batteries is that there are a set number of recharges that equate to the life of the battery. Usually that life is approximately 1,000 charges.
If you use your battery to 50% then recharge, you can do this ~2,000 times. As the life of the battery is used up, the maximum charge lessens which means where you may have had 8 hours of play time when the battery was new, you will only have 6 hours as the battery life is used up.
In order for a Lithium ION battery to recharge there must be at least a small amount of charge left as a "seed" for that recharge. If you drain a L-ION battery down to zero, it may never recharge again or the max charge will be reduced to an insignificant amount of the original full charge. eg instead of 8 hours you may only get 15 minutes, or 5 minutes, or no minutes.
You are much better off recharging when 50% depleted than using it up til your product stops.
L-ION batteries cannot be repaired only replaced. Most cheap products using L-ION batteries cannot have their batteries replaced.

Electric rechargeable braun toothbrush 500


I had the same problem at the beginning of the year. I think i had bought 3 electric tooth brushes and all seemed to cave in within a couple of weeks. My friend recommended going to Macy's to buy one, which I did and it is still going strong. Maybe you charged it for a very long period of time and it overheat the system circuit? I'm not sure but I would recommend getting a new toothbrush.

My braun toothbrush will not charge it is the 5. in a year. I am very fed up with Braun Oral B. Why is it not charging. Bought this one 5 weeks ago.


Have you left it to charge for a long period of time? Maybe it overheated the power source? If you cant get it to work I would suggest buying at Macy's. They seem pretty reliable and have good warranty's for these sort of things.

Not really, the older NiCad batteries get a memory effect if you keep charging from a half charged state, but modern Lithium batteries do not suffer from this problem.
If thelaptop battery is more than 3 - 4 years old then the battery could be worn out.These rechargeable batteries have a finite number of charge and discharge cycles andwill lose their charge capacity over time, i.e. won't charge to 100% andgradually the charge reduces until the battery won't charge up at all. OR Thebattery shows a 100% charge but when the adapter is disconnected the batterydrops off to zero capacity in a very short time. If the battery drops to anunacceptable charge level then the battery needs to be replaced.

I have bought many rechargeable devices and about 4-5% of them have bad Chinese batteries in them. I also have converted nearly all battery operated items to rechargeables and these often have spotty performance with several out of a couple of dozen not worth keeping. You might try running the batteries down as far as possible and then trying to recharge. If they are NiCads, they may have developed 'memory,' a known weakness of that type and NiMh batteries in particular seem to need several charge/discharge cycles before they will come somewhat up to their rated capacities.

The plastic connecton has a coil in it, much like how a transformer is done. If you read up on how a transformer works its pretty much the same principle as it works on Induction. There is a coil and core iron in the end of the toothbrush and in the base, this creates AC current which inturn causes induction to flow through the coils and charge the battery. And about the reason why it is not charging is probably down to the battery being flat ( happens even when new ) or there is a loose connection when it was being transported.
Hope this helps.

How long does it take to recharge my oral b toothbrush and should it work when put on charger sraight away


The first time you use the unit, it should be charged for 24 hours or more.
When it needs charging, my unit takes over 24 hours to fully charge and then lasts around 14 days until it needs another charge.

After charging the wii remotes in the base until


I don't think you are doing anything wrong, just the setup you are useing is'nt as effective as you would like.

I use the energizer rechargeable (NiMH) batteries with the energizer 15 minute charger. The other batteries and chargers just don't seem to work as well. I get several hours of play time on a single charge, where I was only getting about 1/2 hour to an hour with the others. **No I am not a paid endorser, I just use and like the product!**

Hope this helps, please let me know how you end up or if I can help more.
