Review on 🔋 FC999 Model MaximalPower Universal Battery Charger Station for Alkaline, RAM, Ni-MH, Ni-CD, AA, AAA, C, D, 9V Batteries with Organizer Case by Ibraheem Burna

Tried four AA alkaline batteries for the first time. One of the four AA alkaline batteries died (green light) after about an hour, while the other three continued to charge. I didn't know if it was safe to remove a battery while the machine was still running, so I didn't. I waited for the other three to finish. But while on my PC across from the charger I heard a "pop"... Unfortunately the battery which was green (charged) exploded and acid flowed into the charger. I cleaned it up quickly with paper towels, but I'm not sure if it's safe to use. Someone asked if this unit has "overheat protection" - based on the above I'm guessing it doesn't. I'm not sure if it's safe to remove or add batteries while it's plugged in and charging other batteries. I thought it might shock me if I tried it, but now I'm not sure I should keep using it in this state. UPDATE: Even after cleaning the device, one of the pins holding the battery is stuck. I need to buy a new charger, but I want something that won't overcharge/explode the battery.
