Battery Replacement
Professional battery replacement for phones, tablets, and laptops with quality components and expert installation in London
When Your Battery Needs Replacement
Recognizing these signs prevents device damage and ensures safety.
Replace Immediately – Safety Risk
Screen lifting, back cover popping out, or keyboard rising. This indicates dangerous gas buildup – stop using immediately.
Device completely dead even after charging overnight. A failed battery can prevent the device from starting.
iPhone “Service Required” alerts or Android “Replace Battery” notifications appearing in settings.
Plan Replacement Soon
Phone lasts 2-3 hours instead of a full day, or laptop runs 1-2 hours instead of 6-8 hours.
Device turns off at 20-30% battery, or shuts down during demanding tasks despite showing charge.
Takes much longer to charge, or battery percentage jumps around unpredictably during charging.
Check Your Battery Health
iPhone: Settings → Battery → Battery Health. Below 80% means replacement recommended.
Android: Settings → Battery → Battery Health or download AccuBattery app.
Laptops: Windows Battery Report (powercfg /batteryreport) or macOS System Information.
Original vs Alternative Batteries
We offer two quality levels to match your device value and budget requirements.
Quality Testing: All batteries undergo capacity testing before installation. High-quality alternatives typically match 95-98% of original specifications, making them indistinguishable in daily use.
Professional Battery Replacement Process
Battery replacement requires careful handling due to safety risks and strong adhesives used in modern devices.
Safety Preparation
Device powered down and battery discharged below 25% to minimize fire risk. All components grounded against static electricity.
Careful Disassembly
Device opened with specialized tools. Battery connectors disconnected first, then systematic removal of blocking components.
Safe Battery Extraction
Strong adhesive strips removed with controlled heat. Old battery extracted without puncturing lithium cells.
Installation & Testing
New battery installed with proper adhesive. Device calibrated and all functions tested before return.
Water Resistance After Battery Replacement
Battery replacement affects water resistance: Opening the device requires removing original seals. While we reseal with quality adhesives, the original IP rating cannot be fully restored.
Your device remains protected against normal moisture, but avoid deliberate water exposure. Even manufacturer repairs often void water damage warranties.
Why Not DIY Battery Replacement
Battery replacement involves serious safety risks that can cause fires, injuries, or expensive device damage without proper expertise.
Fire & Chemical Hazards
Punctured lithium batteries ignite instantly, release toxic gases, and cause chemical burns. Professional safety equipment and experience prevent dangerous accidents.
Strong Adhesive Challenges
Batteries are secured with industrial adhesives that tear easily when removed incorrectly. Damaged batteries can leak chemicals or catch fire.
Counterfeit Battery Risk
Online batteries often have 50-70% of stated capacity and poor safety standards. We source quality batteries and test them before installation.
Component Damage Risk
Battery access often requires removing motherboards, cameras, and speakers. One mistake can cost more than the original repair.
