All 808 cameras use an internal battery module (3.3V 1S Lipo). This battery module should be able to provide a record time of 30 to 50 minutes on a full battery charge depends on which version you have.
The battery module always has two parts: a rechargeable lithium polymer (LiPo) battery and a protection circuit. The protection circuit does two critical things: it protects the LiPo battery and to charge the LiPo from USB connection.
To replace a battery module or troubleshoot the Battery module related problems, you need to take the screws and the case off (only do this if you are confident in your electronic skills and make sure you understand Lipo battery could be unsafe). The battery module is connected to the board either by solder or by a connector. You might need tools like an multimeter/voltmeter and soldering iron.
SD Card Related Issues and Fixes
If you have problems with battery life, it might not be fix-able. Like many other electrical products, they wear out over time. After many charge/discharge cycles the battery will get smaller on capacity and won’t be able to hold as much charge which will have to be replaced.
Swelled Up Lipo battery
It’s not unusual to see Lipo swelling like a balloon. If you have one of this you need to replace it as soon as you can because it’s not safe. When the Lipo battery quality does not meet the requirements, or when your device is discharging/charging more current than it can handle, you will see this problem.
808 keychain camera does not respond to any button press
If your camera does not respond to any button press try to troubleshoot the issue with the following instructions.
Faulty Battery Protection Circuit
Fully charge your camera battery first. Then check battery module voltage using multimeter, if the voltage should be around 4.2V. The protection circuit might have mistakenly activated the battery protection to disconnect the LiPo battery. This should only happen when the voltage drops below 3.6V. Try resetting the protection circuit by disconnecting and connecting the battery module.
Faulty Battery Charging
The battery module has some charge, but below 3.6V and can’t be charged anymore by the USB connection. It’s normal that the camera will not turn on if the voltage drops below 3.6V.
So the problem could be the charging has failed, which could either be the battery, or the charging circuit. These two problem are difficult to diagnose and distinguish because different 808 versions use different charging circuits.
Try to get a replacement battery, and try it on the same camera. You need to rule out the variables here. If the new battery doesn’t work either, it’s probably the charging circuit on the board, and you will have to get a replacement camera.
Camera only records for a short time – a few seconds or a few minutes
This is usually caused by a bad USB cable or bad computer port that fails to charge the battery, or some flash card problem (too slow or not recently formatted). Short recording can also be caused by a “worn out” battery, a bad battery or a bad charging circuit. Try a different USB cable, USB adapter or USB power source. Maybe try a different computer port or a 5V USB charger. More advanced diagnostics require removing the case (the voltages are live even when the camera is off) and measuring the battery voltage with a digital meter to verify the battery is charged, and that the USB charging is working.
Camera only works when USB connected as a Disk Storage and webcam
It could be a problem with your built-in Battery, make sure it’s fully charged (connected to USB for at least 2 hours). If this doesn’t work, try some basic troubleshoot.
To troubleshoot this problem, try connect the USB cable and when the LED comes on immediately disconnect the USB cable. Hold down the power button, connect the USB cable, release the power button.
If this did not work, try a hard reset (reset button), this will reset the battery module protection circuit. To hard reset you need to first remove the battery connection from the board, and press the reset button and then connect the battery again. If the battery is hardwired to the board you might need to use a solder iron.
my 808-16 has started flashing blasts of light erratically while filming. It is not a vibration problem as it does this when sitting still and filming? My battery is charged as the green light goes out after about 2 hrs. Please Help!!
People who have the 808 cameras they may face many issues with there camera and battery issue one of the major issues with this camera as here it is described. This article is very useful for the 808 cameras users.
Hai, my 808 only record up till 10.11 mins. is it the default recording time? how can i make it record longer? i tried the press shutter button with power button. but it does not work. no system config file in sd card. im not sure what # number i have. its recording at 720x480p/30fps/avi format and configuration tool does not recognized its firmware.
Hi, I have 808 #16 v3 camera. When I charge it in car and filming in same time, I cant turn off filming. Camera is filming while I press and hold turn off button. And after that camera does not want make a film again even when it is on batery. Do you know what is the problem? Please.
Sorry for my bad english,
Hi Oscar, When I charge my 808 #16 the light is red. Is this OK? I just purchased it new and it seems to be working fine.
In ebay, I found a clone keychain camera which is almost the same but the price is 10x lower… (Original $40, Clone $4). I have a GoPro 3 Cam, but I’d like to test the above one in my micro hexacopter… Will it work as same or even similar? I can’t use gopro on it ’cause of weight…
Key chain camra is not start.
Just rec. my 808 16 D and when I charge it a red light comes on instead of a green light—left it charging for 8 hours and the red light is still on. It does work.
Hi, Can you tell me what type of connector the 808 camera/battery has? I can find 1S batteries easily enough but none that seem to have the correct connector.
sir were i get the lipo battery, are other wise using the mobile battery is support
no, you need to get some 1 cell lipo battery (1S). they are widely available on ebay. some 300mah to 500mah should do fine.
Hi. My 808 16 key chain camera doesnt work. when i plug in charge cable green light blink once – after than nothing light…battery is after hour of charging cool.
I tried other cable – but there is the same problem.
I tried the other micro sd card with FAT32 format but still doesnt work.
I tried reset button and disconnecting and connecting the battery module – still nothing.
When i plug cammera to the usb port of my pc – there is no reaction.
*****Can you help me guis?*****
My new camera does not come on. Where can I buy a battery?
ebay, search for 1S lipo.
Sir , where can we purchase the lipo battery for keychain camera.
Thanks for the information its very useful
