    seeing in the second photo you must place where the l B + is seen (positive and in B- the negative of your lenovo charger ... if you have a tester it tests voltage in the charger to identify the positive and the negative of it ... It must also be a red wire (positive) and another black (negative) comments! Greetings!

    the other pins are to regulate the battery charge ... YOU DON'T NEED THEM when connecting an external charger to the original one but I recommend connecting the external charger cables directly to the battery to be charged and not to the original battery charger as well It will not charge because it will not pass power from the charger to the battery --- it is understood !!! comment !!!

    What voltage is the battery? The charger is 20volt what voltage is the battery to charge?

    Do you have tester (multimeter) to measure voltage?

It must also be a red (positive) and a black (negative) cable --- if you still have the chip (that is, you didn't cut the chip) the positive is the inside one and the negative one is the outside one !!! comment !!! greetings !!!

    You will not run any risk and the other pins that are?

    b or the other pins are those that are responsible for activating and deactivating when the battery is charging (so that the battery is not affected with an overload and thus waste the time of its useful life) you when placing another different charger that stage is more than Obviously it is not going to run (since you do not use the original charger but an external charger by placing the load alone) for this reason you must leave it charging for a while and then disconnect it yourself since it will only start heating the battery once it charges thoroughly!!! likewise nothing happens if it overheats, if it happens that life uti

    I left 10 minutes and charged two LEDs with a 5 minute more charged everything but the Lenovo external charger warms up a bit I would say it worked but only leave it 20 or 15 minutes or else the external charger could burn

    Of course reheat because you are connecting it through the original charger (which if you connect it directly to the battery that will not happen !!! I recommend you connect to the battery directly !!! That if you must first tell me what voltage the battery handled .. If it is not 19 volts you are going to spoil the battery in less than 5 charges you have to put a charger that is the same voltage as the battery you are trying to charge so that although it will eventually break down !!! it lasts a few amount of charges more ... if I charge yan fast it is clear that the charger is of many amperages of delivery ..... comments !!
