Replace Lithium Battery in colorfly ct800 tablet

Replace your micro USB charger. You usually can get three to four years of hard use out of that lithium battery.

this tablet seems new to me but however there is a way to open the tablet with a heat gun and a spudger knife but do be careful opening the device lithium batteries are highly dangerous if poked or damaged in any shape or form

Battery is shot and the 99% is a false reading. Send it in for repair.

could be the lithium battery. Retailers will tell you you cannot open the tablet as they are sealed units. But after being told this by a retailer where I originally purchased my Tablet I managed to work out how to open my tablet and replaced the battery. The battery is not cheap and is hard to transport due to flight risk of lithium batteries. I had to purchase the battery online locally rather than from cheaper overseas sources but by the time you pay for postage and currency conversion it is about the same price.

It may be a faulty charger ac - dc adapter but in my case it was a dead battery. the tablet was about 2 years old when the battery became faulty

contact wherever you bought it,it will be warranteed as long as you used the proper charger and unplugged it when done charging,but,it sounds to me that you might of used the wrong charger

Any lithium battery is bad news. Research, I think its Boeing that said the answer is the lack of oxygen. So there is your safe lithium battery, cut off the air, after all a lithium battery brought down a huge airliner

Whilst I am not familiar with the brand of tablet you have, please be warned that it is in a dangerous condition. The "silver pouch" you mention is the Lithium battery that powers the tablet, and the fact that it is swollen means it is faulty and could rupture (split open) anytime. The danger here is that the Lithium inside the battery will ignite in a very hot flame if it comes into contact with air, which it obviously will if the battery splits open. Do not store the tablet inside your home until the battery has been replaced. My advice would be to unplug and remove the battery if it is plugged into the mainboard of the tablet, place it inside a fire resistant container, and take it to your nearest battery disposal location. Then you can most probably source a replacement battery either on eBay or from the store where you purchased the tablet. If the battery is soldered in place and you do not have the tools or expertise to remove it, then I'd advise that you call a local PC or cellphone repair company and see if they are willing to remove and replace the battery for you. If they are, take the tablet to them (in a metal bucket or similar, just in case the battery fails). The swelling of the battery's casing is the result of gasses being generated inside the battery, and indicate that it may be in a very dangerous condition, so I stress again, it is a potential fire hazard and should not be kept it inside a building unless it's in a fire retardant location.

The only way will be to replace the battery. Lithium battery's only have a limited service life, and begin to degrade quite markedly after a couple of hundred charges. The older the battery is, the less capacity it has for storing electricity, so your Tablet has detected that the battery within has lost 50% of it's original capacity. If the Tablet is relatively new and you have not recharged it many times, you may be able to claim a replacement battery under warranty from the supplier {:o)

Frequent Charging Shortens Battery Life Frequent charging shortens the life span of a Lithium ion battery. Batteries should be charged only after they expend all their power. b> Switching Batteries Switching batteries helps preserve battery life: If a cell phone or computer user puts in a spare battery while separately charging the primary Lithium ion battery, that helps extend the life of both batteries. b> Removing Batteries Most laptops charge the battery when a user plugs in the AC adapter. Users can adjust this setting by changing the power options. Windows places this option in the Control Panel, while the Gnome Linux desktop places power options under "Administrative Tools". Cell phones incorporate their own power-saving features that the user usually cannot control. b> When to Replace a Lithium Ion Battery If a laptop battery does not hold a charge for more than a few minutes, a user must replace the Lithium ion battery if he wants to use the computer without an AC adapter. Other Ways to Extend Battery Life Storing a battery in a cool, dry environment causes a lithium-ion battery to last a little longer and reduces the frequency of needed battery replacements. Hope this helps.
