🔋 90-day warranty is the industry standard for replacement batteries. Batteries naturally lose capacity over time — this normal wear is not covered. Warranty applies to manufacturing defects only.

Restore the reliable battery performance of your Oukitel K15 Plus with this S82 10000mAh replacement battery. The Oukitel K15 Plus is a rugged phone built for outdoor use, with a large 10000mAh battery that supports long working hours, GPS, camera, and daily communication. After regular charging cycles, the battery may show signs of aging, such as shorter runtime, sudden shutdowns, slower charging, or a swollen back cover. This S82 Li-ion Polymer battery is designed to fit Oukitel K15 Plus and bring back full all-day power.
Designed for Reliable Daily Use: The S82 battery uses high-density battery technology with multi-layer safety protection against overcharge, over-discharge, and short circuits. It is factory-tested and carries CE, RoHS, and UN38.3 certification. With 10000mAh capacity and 3.85V rated voltage, it supports stable performance for calls, navigation, photos, and outdoor apps. The battery is a practical replacement option for Oukitel K15 Plus users who need dependable power in daily life and outdoor work.
Compatibility Note: Fits Oukitel K15 Plus only. Please confirm your battery model before ordering — S82 is printed on your current battery. Verify that your battery matches the model number, rated voltage (3.85V), and capacity (10000mAh / 38.5Wh). This device has a sealed rugged design — professional installation is recommended. Using an incorrect battery model may cause improper fit, charging issues, or incorrect battery reporting.
Battery Care Tips: Use a compatible charger, avoid extreme heat or cold, and try not to drain the battery to 0% often. For daily use, keep the battery level between 20% and 80% when possible. If you store the phone for a long time, keep the battery at around 50%. Because the Oukitel K15 Plus is an IP68/IP69K rugged phone, water resistance depends on the back cover seal. After replacing the battery, make sure the rubber gasket is clean and intact, or install a new seal, and close the cover correctly. If you are not confident, ask a professional technician to do the replacement.
