    Why You Need This Battery

    Your Mitel 5613, 5614, or DT390 DECT cordless phone is a critical communication tool in fast-paced environments like hospitals, hotels, and warehouses. When the original battery starts to fail shorter talk time, unexpected shutdowns, or the handset refusing to hold a charge productivity suffers. Replacing it with a cheap, lowquality battery often leads to false capacity readings, swelling, or failure within months.

    This replacement battery solves that problem delivering true 700mAh / 2.6W h capacity with brand new Grade A Li-ion cells. What you see is what you get.
