Sounds like your battery has had it mate - grab yourself a new generic, see if that fixes the problem, otherwise try a complete software reinstall

Not turning on. Blue light flashes then turns off


Fixing a Jabra with charge problems, demonstrated by the LED just flashing once when placed in the docking station/charger..
When my Jabra stopped charging after lying several months unused in a drawer, I looked around on the internet for a way to get it to charge again. All the methods to recover the battery that I read on the internet are probably dangerous for both the Jabra and the user. So here is a relatively safe and tested way to recover the battery.
Please note, Jabra does not supply any spare parts, there are none.....so fix it or throw it in the trash.
Its a good idea to charge them every 3-6 moths, to stop the problem ever happening to you.
I know this fix I will describe here works on both a Jabra 200 and a 250. I would expect it also to work on the 250V as well, though I have not had a problem with mine up to now.
Some other Jabra models, especially if they demonstrate the same problem as defined in Problem definition below with the indicator LED, may also be recoverable in the same way. Its worth trying.
Don't forget that all Jabras are designed as "throwaway", never to be repaired....that is probably true of most if not all Bluetooth headsets....Jabra models 200 and 250, I find to be the most comfortable ones to wear for long periods, whilst driving for example.
Problem definition.
First let me define the problem for you. If the battery in some Jabras (I cannot say all as I don't know if that is true), gets too deeply discharged by non useage, the charger will not recharge it. The indication that this is the problem is also easy to checkout, just stick the charger in a wall socket, connect the docking station and while watching the indicator LED on the Jabra, slip the Jabra into the docking station. If the LED just blinks once, you have the discharged battery problem. Probably fully recoverable if you are good with your fingers and have some knowledge of electrics or electronics.
Problem fix.
The only way to get the charger to restart, is to get the battery charged to at least 3 volts (its a 3.7 volt battery).
The best and safest method is to get hold of a lab power supply with adjustable voltage and current. I set mine to a fixed 3.7 volts and maximum of 300 milli amps. If you do not have access to such a power supply, look further down this article for a method using either 2 or 3 dry batteries, depending upon the type of battery and the terminal voltage available.
You will also need a voltmeter for either method.
Method
Remove the tiny crosshead screw that holds the Jabra togetherand gently and very slowly pull the headset apart, the wires are easily damaged, are very short, fragile and difficult to repair if you break them.
The Battery is obvious, but how to get to the contacts is not that easy. Carefully slip the battery out of its location and peel away the insulating tapearound the top end where the charger PCB is also mounted.
Identify the + and - of the battery either by either looking at the label (usually on the other side of the battery to the connections) or by measuring the voltage still on the battery and at the same time identifying which pole is the plus. Mark it. Usually a problem battery will have around 2.3 to 2.4 volts or less....
Apply the voltage/current that I detailed before from the lab supply (Plus to Plus, minus to minus) and watch the current meter on the Lab power Supply unit, it should go slowly down as the battery charges up. Stop charging for at least 10 seconds after 1 minute or less, constantly check battery temperature at the same time with a spare finger. If the battery starts warming up. STOP CHARGING. Let the battery cool down.
Always wear protective glasses in case the battery explodes.
Measure the battery voltage from time to time and once it is over say 3 volts, stop charging and attach to the docking station and see if the charger will now charge properly. If not, charge for another minute or so.
If it charges properly,carefully put the Jabra back together and continue charging.
First charge cycle after "Repair".
The first full charge after such a repair may take up to 12 hours before the LED finally goes out, even though a "normal" charge will generally only take 2 hours. This demonstrates clearly how run down the battery really is/was....
Another method to recharge the Jabra Battery for those without a Lab power Supply.
Connect 2 x 1.5 volt (NOT 1.2 volts cells as they will not charge correctly) together, or 3 x 1.2 volt cells together and use them to charge the Jabra internal battery with.
Monitor voltage and battery temperature constantly, till the battery voltage is above 3 volts, then try the normal charger as before. Do carefully iIdentify the positive and negative sides of the battery and apply the battery positive to the + side of the battery. The other polarity to the - side of the battery.
Take your time when charging and monitor both the battery voltage and its temperature carefully.
A series resistor may be used to keep the maximum current to a set maximum....say 10 or 20 Ohms.

FOR HOW LONG CAN THE BATTRY LAST BEFORE YOU CHANGE IT


How Long Does the Nokia E65 battery REALLY last?
Ever wonder how long the phone battery actually lasts? For the first use of my Nokia E65, I charged the phone for 24 hours after receiving it (still not sure if this is necessary), then took it off the charger Saturday afternoon. The battery low warning first sounded 54 hours later. This was after
•Calls: Around 15 calls made and about 3 calls received, with almost 40 minutes call duration in total.
•Data: 726kb data sent and 3.96mb downloaded
•WIFI: About 20 minutes of WIFI use
•Applications: Use of Skype and Gmail application as well as a bit of Nokia Maps and Google Maps
The battery eventually gave up after 2 more hourse of standby. The Nokia website says the following about the Nokia E65 battery:
•BP-4L 1500 mAh Li-Po standard battery
•Talk time (maximum): GSM up to 11 hours; WCDMA up to 4h 40 min
•Standby time (maximum): GSM up to 18 days; WCDMA up to 20 days;WLAN idle up to 170 hours

If you are wanting to make comparisons with the Nokia E71 battery life, this is what the Nokia website claims for the Nokia E71. The Nokia E65 and E71 both use the same battery - BP-4L 1500 mAh Li-Po battery but E71 is slightly more demanding on the battery life.
•Talk time:- GSM up to 10 h 30 min- WCDMA up to 4 h 30 min
•Standby time:- GSM up to 17 days- WCDMA up to 20 days- WLAN idle up to 166 hours
If you are willing to help, maybe you can do the same experiment for your Nokia E65. Use the call logs and the data counter under "Connectivity" and measure how long your Nokia E63 battery lasts with "normal" usage. Report your findings in the comments below and someone just as curious as you googling battery life E65 will also benefit from your efforts.
Your mobile habits may not be as demanding as me but I hope this helped you in your battery life calculations for the Nokia E65.
To charge a battery from empty to full, it took 2 hours and 40 minutes


....... If you are willing to help, maybe you can do the same experiment ... It lasts me about 40 hours before I get a battery low warning .... I got my Nokia E65

The battery life in my lg KC910 is not lasting very long, I bought a new battery and this is just the same, any help please


These are the specifications:
http://www.lge.com/products/model/detail/kc910.jhtml

Standby time hours :320hr(2G), 350(3G)
Talk time hours :220min(2G), 220min(3G)

If you take photos and listen to music then it will last less.
These values are an estimate of how long the battery should last.

If you are not getting these values then return the phone.

No sound, not able to pickup receiver


On the CS55 headset itself, right below the speaker that sits on the ear is a cover that can be removed.  Inside is a small special battery.  The battery life tends to last about 3 years, and at that you should be getting 8 - 10 hours of talk time.  Once it's decreased to about 4 hours of talk time in a day, it's about time to replace the battery.

Short time between bluetooth charges


You should have up to 4 hrs talk time, and 180 hrs of standby.

Make sure you charge the 2050 until the l.e.d. turns off. As long as the light is on, its still charging.

If you did that, I would return the unit for exchange, your may have a defective battery.

Motorla Slvr L7 Won't hold charge


It depends on how much talking your doing. The Slvr is known for its low talk-time battery power. My slvr would last about 3 to 4 days on a charge, unless i was talking on it a lot. sometimes i would be charging it every other day. So it really all depends on the talk-time. Invest in a car charger for sure.

Phone loses connection after few minutes


I looked up the battery specs for your phone. They are 3 X 200mah= 600mah battery packs. They should last 8 hrs talk time with the headsets. This style of battery pack in my experience only last about 1 1/2years and sometimes longer and "sometimes" shorter...much shorter. I bet you never had problems when you first got them. Basicly this "battery design arrangment" goes back many years before newer battery technlogy was developed. But designers still insist on using them even today. They are cheap to make. ****Time to replace them with new ones.**** Make sure you follow the mfgs charging instructions: "After battery installation, place the handsets in their base unit or charger and allow to charge for 16 hours before use. You can keep the battery charged by returning the handsets to their base unit or charger after each use. When the battery is fully depleted, a recharge takes about 12 hours. Average talk time on a fully charged battery is about eight hours depending on environmental conditions, standby time is approximately four days." Good luck
