Don't sweat things about the internal battery replacements I would say if it turns out the battery replacements are overpriced and they decide to make you send in your scanner to an authorized repair center to do it and won't sell direct to you and give you clear DIY instructions , then F 'em I believe the logical thing for me would to just get be a trim external battery velcroed to the back of the tablet to get me by unless the defective one inside starts smoking or the voltage regulator dies. Just so Autel knows, there are plenty of economical aftermarket external battery alternatives now becoming available if the direct internal replacement batteries are not priced right ,or made a hassle or mystery to buy and install. Please be fair ,we are technicians ,most of us can follow instructions, use a DVOM to test a voltage regulator and user a solder gun if need be to change a battery. Thanks in advance
