The MITSU battery is an ideal choice if you’re looking for a high-quality replacement for the original battery in your DELL INSPIRON 15 (5542) and 14 (5445) laptop. With a capacity of 43 Wh (approx. 3800 mAh) and a voltage of 10.8–11.1 V, it provides stable power and confidence for everyday work and entertainment.
The manufacturer uses premium A-grade Li-ion cells and applies a 6-stage quality control process, resulting in safety and long service life. Integrated protections (OVP, OTP, SCP, OCP) safeguard the device against overvoltage, overheating, short circuit, and overcurrent. The truly stated capacity and slower nominal capacity fade compared to cheap replacements ensure reliable runtime between charge cycles.
