Braun series 3 no longer holds a charge. what can I do?


It is not that young anymore. The rechargeable battery is (almost?) dead. It is almost impossible to replace it. I once tried it, took me more than a day yo put everything together and still it never was as before.
I have bought a new Braun (799) and I'm convinced this one will live longer. The rechargeable battery in this one, you can shave one hour before you need to recharge it. It lasts a week with me, or sometimes even longer, before I have to charge it again.

Perhaps you just use the shaver with the power cord, like we used to do for 20 years, and start saving for a new one?

How to Help HP Pavilion Laptop Power Battery Using Problems


Hp laptop users might experience that the battery is overheated, or the laptop battery suddenly stop charging. Sometimes, the battery health "good" but the battery does not hold a charge, etc. So, how to fix these problems?
First of all, you know that the most common type of AC power adapter involves a small box, with one wire to go to the computer and another wire to go to the wall. There is usually an LED light on it, to tell you that it is on. When your laptop doesn't work, you need to troubleshoot the AC power supply, system board and the battery are functioning correctly. The battery is an important part. It supplys power to the input-side of the voltage regulators, just like the power from the AC adapter. Additionally, there is a charging circuit, which uses the power from the AC adapter prior to the voltage regulators, to charge the battery. (By the way, this is why the AC adapter voltage is always rated higher than the battery's rated volatge-- you need higher voltage for charging.)
Verify the Hp laptop battery like this:
1. Insert the battery into the battery compartment on the bottom of the notebook PC.
2. Connect the AC power supply and allow the battery to charge for 15 to 30 minutes.
NOTE: The power LED, located near the power icon (displayed as a lightening bolt on most PCs) , should glow while the battery is charging.
3. Unplug the AC power adapter cord from the notebook PC.
4. Press and release the Power button to start the computer using only the battery as the power source.
If the PC does not power on, then the battery needs to be replaced. Contact HP service and support for further assistance.
If the notebook PC does power on, the battery is functioning, however you should run the HP Battery Check utility to evaluate the battery's health.
NOTE: If you have purchased a second battery for your notebook PC or you have access to an identical battery, you can also check the battery by inserting the second battery into the PC and performing the Troubleshoot the battery steps again.
Your new HP laptop battery comes in a discharged condition and must be charged before use (refer to your computer manual for charging instructions). Upon initial use (or after a prolonged storage period) the battery may require two to three charge/discharge cycles before achieving maximum capacity. When charging HP laptop battery replacement for the first time your computer may indicate that charging is complete after just 10 or 15 minutes. This is a normal phenomenon with rechargeable batteries. Simply remove the battery from the computer and repeat the charging procedure.
It is important to condition (fully discharge and then fully charge) HP replacement laptop battery every two to three weeks. Failure to do so may significantly shorten the battery's life (this does not apply to Li-ion batteries, which do not require conditioning). To discharge, simply run your device under the battery's power until it shuts down or until you get a low battery warning. Then recharge the battery as instructed in your user's manual. If replacement HP laptop battery will not be in use for a month or longer, it is recommended that it be removed from the device and stored in a cool, dry, clean place. It is normal for HP laptop replacement battery to become warm during charging and discharging.
How to solve the batery can't be charged?
Possible Reasons:
a.The battery has no voltage.
b.There is problem with charger, as it has no output electric current.
c.Low charging efficiency due to external cause.
Best Solutions:
a.Test whether the charger has voltage and output electric current or not.
b.Check if the charger is well contacted with battery.
c.Activate the battery with voltage and current 1.5 time higher then the highest ones of battery. (Use this method only when the battery can't be charged.)

Battery doesn't hold charge for more than a week


All batteries will eventually fail to hold a charge. The battery chemistry and how you charge it can change how long the battery will last. The DMC-FS4 has a Lithium-ion battery so it shouldn't have as much of the memory issue of older rechargeable batteries. (This is the "you routinely recharge the battery when it's at 50% then it always stops working at 50% charge" problem.)

How old is your battery? Eventually you will need a new battery but the time to replacement will depend on the number of recharge cycles. With a Li-ion battery, I'd expect several thousand recharges before failure. Temperature and usage will effect this. The battery does lose charge even when not used.

Be careful, some versions of the firmware look for Panasonic's specific batteries or a "that match the Panasonic rigorous specs".

I've seen a few devices where the charger failed before the battery. If a new battery doesn't seem to be charging, replace the charger. I hope this helps.

HP Pavilion DV5000 battery charging problem


Sounds like you need to calibrate the battery, it is supposed to be done every 3 months. If it is not done, your battery will display the same symptoms are you describe. Yes, this holds true for adding a new battery also.

Here is HP's instructions on how to do it. You want to scroll down to the section called "Calibrate the notebook PC battery".

Battery with HP Pavillion DV5000 won't work. Do I need to replace the battery or is there a battery charger I could use to recharge the battery? Dianne


You can order a power cable online or pick one up at your local computer store. They should run between $80-150. The battery itself is very expensive to purchase but is rechargeable.

CanI use power rated 19volts instead of original power supply 18.5volts


As you have found... half a volt at that amerage should be just fine...

If it helps, I just bought an aftermarket replacement of the correct voltage and amperage for my nx9010 from eBay for $15AU delivered. It'd probably help when it comes time to sell your laptop =-]

Razor battrey


Did the phone show it was charging on the display? Was the charger firmly connected to the phone? The batteries will go bad after a period of time of recharge cycles. I have bought replacement batteries for my RAZR on eBay. Remove the battery and do a search on eBay for a NEW battery from a dealer using the battery P/N on the battery. I found a higher capacity battery for mine that lasts even longer on a charge than the original one that came with my RAZR. You can do a search on eBay for "RAZR battery". Look at the mAH rating on your battey, Try finding a replacement with the same or higher rating than your original. The higher the mAH rating, the longer it will last between recharge cycles.

Good luck!
