I bought a replacement battery for my Razer Blade Stealth 13.3” (2017). After installing the battery, it worked fine for a while. Then I left it to charge fully and kept it plugged in while the laptop was powered off. When I came back, the battery wasn’t working at all. I also bought a second replacement battery and installed it and the same thing happened; it worked fine, sustained charge and was charging normally. I left it plugged in and then when I tried powering the laptop on it wouldnt do anything. I used a multimeter to check and saw 0V across the terminals of both batteries. With the dead battery connected and the laptop being plugged in for power, the battery icon on the taskbar shows the battery as normal and plugged in and says “(96% available, plugged in)”, but as soon as you remove the charger the laptop switches off and doesnt power on again (on battery). I’m not sure why this happened since laptops have protection from overcharging. The original battery that came with my laptop works fine, no problems with charging (so it’s not a fault in the charger), the reason I wanted to replace it was because its capacity had decreased and wouldnt power the laptop for longer than 20 mins. I apologize for the long description. Any information on why this might have happened would be highly appreciated.
Hi @maazo_o, To eliminate the possibility of faulty batteries, create a Win 10 battery report to check the status of the battery. Compare the Design capacity value versus the Full Charge capacity value. With a new battery they should be the same or close to it.
From what I can tell this sounds like you are using a power supply which is ABOVE the rated voltage of your blade I suggest double checking the voltage input of your blade and the output of your power supply, overcharge protection protects you from well, overcharging, it does not mean there is overvoltage protection. If this happens to be the case I recommend purchasing a new charger from RAZER’ s webstore here: https://www.razer.com/gaming-pc-accessor… it is currently out of stock but when its back in I suggest getting one if the power supply was the problem. If the original battery worked then maybe the battery specs of the ones you ordered were for a different model and did not function properly, that or you just have insanely bad luck with batteries, batteries dying during shipping isn’t all that uncommon due to heat
