✅ Why Our Warranty Stands Out

Unlike marketplace sellers with short buyer protection windows, we handle claims directly — no automated disputes, no endless back-and-forth.

🔋 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.

Frequently Asked Questions

The BLPA69 battery is compatible with OPPO K12x (model PJT110) and OnePlus Nord CE4 Lite 5G. The OPPO K12x features a 5500mAh battery and supports 80W SuperVOOC fast charging. If your K12x or Nord CE4 Lite battery drains quickly or won't hold a charge, this is the correct replacement. For reference, US retailers like BatteryUs sell this battery for $23.88 with free shipping. Please verify your device model before purchasing.

The BLPA69 battery has a typical capacity of 5500mAh (rated capacity 5375mAh) and a rated voltage of 3.91V. Charge limit voltage is 4.5V. It is a Li-ion battery built with grade A cells and is CE, RoHS, and UN38.3 certified. The battery supports the original 80W SuperVOOC fast charging capability of the OPPO K12x.

Professional installation is strongly recommended. The OPPO K12x has a sealed design with strong adhesive. Replacing the battery requires heating to soften adhesive and careful prying to avoid damaging the display. If you choose to DIY, watch a full teardown tutorial before starting, use a heat gun at low temperature (no more than 70°C), and never reuse a battery after removal. Incorrect installation may damage the phone or break water resistance. Third-party repair shops typically charge $15-30 for labor.
