SOURCE: headset not charging

Sometimes it takes longer than two hours. Leave it plugged in overnight if you can. The indicator light should go off after fully charging.

SOURCE: Battery Charger Olympus li-40c

I had this problem a few weeks ago (i.e. flashing red LED). All I did was remove the power plug from the charging unit, turned it around 180 degrees, then plugged it back into the charging unit. Red LED came on steady & the battery (which is the one that came with the camera) recharged as normal.

Problem with hitachi chargers


I live by hitachi, one of the good things about it is lowes will exchange them as long as you have a receipt and it's under 30 days. If not chargers are not very expensive, or you can send it back for repairs. I have 10 of those combo packs and never had a problem with a single one, for you to get 2 is a freak accident.

Basically you need to remove the right side padding and take out the 3 screws. This gets you access to the battery. The battery is a standard 3.6V lithium battery. Pretty much the same that is in most cell phones and many small toys. You can simply replace the battery with something like:

Or... here's what I did... add a lithium USB charger to the battery.

Now, if the battery dies I can plug it into USB and the phone will work while it charges.

Battery won't charge up


One or more of the cells in the battery may have died while it wasn't being used. LI-Po batteries are memory resistant but they can still develop one if they're left fully discharged too long or at a half charge too long. They require full charge\discharge cycles to keep them from developing a memory.

Is helicopter off when charging? Will not charge when powered on.
Light on charger should go off when plugged into helicopter.
Also, are you running battery dead? This will destroy a Li/Po battery. Never fully drain battery. Run only until you cannot maintain altitude. Land and power off. Cool for 10 minutes. Charge. Cool for 10 minutes. Skipping either "cool-downs" will also destroy your battery, albeit slower than the full discharge which can sometimes kill a Li/Po battery in only 1 or 2 cycles especially when they are new. Have any friends with a cell phone or laptop (Li/Po batteries also) that they hate because "it's always dying" or "the battery only lasts like 4 hours" whether or not they know why, it is ALWAYS because they rarely charge them fully, especially for the first few charges which are crucial, and the often run the things dead until they won't even turn on.
Back on topic, I use and recommend the usb power adapter. When plugged in using the USB wall adapter, does the charging light still stay on? Certainly if "yes", and still likely if "no" sadly, this to me sounds like a fried battery, which, if it, as I suspect, was caused by frequent or early full discharges and/or hot charging/flying... then you're screwed. The batteries are cheap but quite tricky to replace. Need a steady hand and a needle tipped soldering iron and solder barely thicker than hair.

Hope I've helped,
PvT

How will be i identify it is fully charged battery i charged for 45 minites.But the battery will not be fully charged. please send me the solution for this problems


If using usb charger use usb port on back of desktop, not data port in front, also most laptops do not have fully powered usb ports due to battery consumption. The wall charger, or a usb charger plugged into a usb/ac adapter (like included with ipods and kindles or sold seperately) is your best bet for reliable charge.
Charging unit should have a light on it.
When charger is plugged into power source and not helicopter, the light will show you {#1} what it looks like when battery is fully charged. Typically this is steady on, and usually red. (sometimes green) When you connect helicopter to charger, the light will change (usually goes dark) to signify it is charging {#2}. When light comes on fully (or completely returns to #1) then charging is done. (Note: charging using a laptop usb or a front side data port usb can take several hours.) Watch the light on charging unit when you unplug helicopter, if it gets brighter, helicopter is not charged, plug it back in. Make sure to let battery cool for 10 minutes after every charge and 10 minutes after every flight, and never run battery all the way down. As soon as you can't maintain altitude, land and power off. Fully draining a Li/Po battery weakens it's ability to hold a charge and can ruin it.
If all else fails, replacement batteries are available from Amazon and many others, they are cheap (around 5$) and very easy to install with no soldering and just a small screwdriver.
Hope this helps

The red light is always on, and it doesn't seem to be charging. Its almost brand new.


Same thing started happening to me. The red charging light was initially going out but then after a few days use started staying on. I assumed that the battery was damaged and bought 3 new batteries but the red light is still staying on when I charge the new batteries.

I suspect that the mains charger I was using (same voltage but not the recommended charger) has perhaps damaged a component inside the EFLC1003 unit which is now not letting the power through to charge the battery.

You're likely doing one of two (or three) things:

Undercharging. Make sure to charge until light on charging unit is fully bright. If the light on the charger gets ANY brighter when you unplug the helicopter, then it's not fully charged. Note that if you are using a usb charger, that most laptop usb ports and front side desktop data ports are not fully powered to the required 5volts DC, and so can take several hours to fully charge the battery.

Over-discharging. Once you cannot maintain altitude, land helicopter and power it off. Draining a Li/Po battery fully, or even close to it, will weaken it's ability to hold a charge, and can ruin it entirely. Not like the old Ni/Cad rechargeable batteries.
Improper care. Batteries should be allowed to cool for 10 minutes after every flight, and 10 minutes after every charge. Like over-discharging, overheating will always weaken, and can destroy your Li/Po battery.

hope this helps let me know

1) Ensure you're fully charging. Indicator light on charging unit should NOT get brighter at all when you unplug the helicopter. If it does, then plug helicopter back into charger until light stays the same when you unplug. Note: If you're charging with a usb charger and are using a laptop or the front side data port on your desktop, these may take several hours to fully charge as they are usb 2.0 and do not carry the full 5 volt dc charge. Use powered usb (3.0) on back of desktop, or get a usb/ac adapter. Normal charge time approximately 1 hour. Go by the light, though.
2) Don't run them dead. As soon as you can no longer maintain altitude, land and turn off helicopter. Fully discharging a Li/Po battery (particularly when it's new) will cripple it's ability to hold a charge, and can ruin them.

hope this helps

How many hours we should charge the battery fist time Nokia-2700


There are basically 3 types of chemicals currently being used for cell phone and laptop batteries. Ni-cad, Ni-mh and Li-ion. There is a fourth makineg its way in Li-ion polymer. A couple things are consistent for all types of batteries no matter what chemical is inside. You must initially give the battery a 12-14 hour charge on the home charger. (Don't use a cigarette adapter for the first charge. This conditions the battery and don't take it off the charger that first time even if the charging indicator says it's full after 3 hours. Also the manufacturer's also state to run it thru 3 charge cycles. What that mean's is that you fully charge and fully drain 3 times. 1 full charge + 1 full drain = 1 charge cycle. Here's where the way you charge the battery starts to differ.

Ni-cad: Mostly only on older devices, has a "memory" effect, should be drained before a full charge is put on it, should be removed after overnight charge or can be overcharged and burnt out.

Ni-mh: Still used for some devices, has slight memory effect but not enough to have to fully drain before the recharge, should not be consistently left on charger after full charge that can eventually burn out battery and shorten usage time.

Li-ion and Li-ion polymer: Used on a lot of newer devices, has no "memory" effect, should be recharged as often as possible, actually likes to be charged and draining it regularly can cause the usage time to be shortened, can NEVER be overcharged so whenever you're near a charger put it on there. Besides those benefits a li-ion battery is lighter and smaller but the chemical can hold more charge than Ni-cad and Ni-mh.

So the one reply to your question said to error on the side of draining the li-ion batteries. This is incorrect information. You want to charge the battery before it gets below a 20% charge. Also batteries will not go bad from accidentally doing the incorrect charging procedure here and there but normally follow the correct procedure. One last note try to use the home charger more often than the cigarette lighter charger for best long term results. Cigarette lighter chargers do not give a full charge (about 95%) which in the long run can damage any type of battery listed.

Stopped recharging


Two things: 1) This mouse and charger does not like rechargeables larger than 1800mAH. The light on the front will(sometimes) go red if you use a higher rated battery than the 1800mAH. You said you replaced the batteries, but might want to check their rating. 2) My mouse gets harder and harder to get a good connection when putting it in the cradle. Might be the contacts are getting dirty. When you put it in the charger, you should see the optical beam (red on the back) go out and the green light on the front turn on. If this doesn't happen, it isn't connected.

You do have the cradle plugged in and the batteries installed the right direction in the mouse? I know it's obvious, but the questions always have to be asked.
