Hi I replaced my laptops battery cells. Now when I connect the battery to laptop it says fully charged but when I unplug the AC adaptor the laptop shuts down imidiately like I have no battery on it. I checked all connections and all it's fine. The plus and minus terminals of the battery have zero volts but the cells have 11.5 volts. I use the resistor to activate the solid-state switch but with no luck. I have to mention that I replaced the cells without keeping "alive" the circuit board. Why is this happening? Is there any way to bypass the board? thanks

Over time, a battery is charged and discharged. It’s these charge and discharge cycles that wear the battery the most. A battery pack is only good for so many cycles. Typical cobalt-based lithium-ion battery packs will last anywhere between 500 to 1200 cycles depending on the configuration and application. This usually comes out to 3 to 5 years in most use cases.
The hot ash method should be used as a ‘last resort’ – you only use this when all else fails. First, you need to light a fire and let it burn down to hot ashes. Then remove the filler/vent caps from the top of the battery, take the battery off the car, and place it on the hot ash. Be careful and make you it doesn’t catch fire. The hot ashes should warm the battery up. Reinstall the battery carefully and try to restart your ignition.
The condition of your car’s battery is certainly worth noting. It’s essential to getting the car started by supplying a powerful current to the starter motor and ignition system. If your battery fails, you may be stuck wherever you are!
