Battery Replacement

Low maximum capacity, a high cycle count, or unexpected shutdowns? We replace worn lithium-ion batteries with high-capacity cells that meet or exceed OEM mAh ratings.

Overview

How we handle battery replacement.

Every lithium-ion battery chemically wears down with each charge cycle. Once maximum capacity drops below about 80%, the battery can't deliver the peak current your processor demands, which causes lag, throttled performance, and sudden shutdowns. We start with a full power diagnostic to confirm the battery is the real cause: we read the cycle count and maximum capacity, and check for abnormal current drain from the board. The old cell is safely removed by releasing its stretch-release adhesive strips, and a new high-capacity cell is installed with fresh adhesive. Swollen batteries are handled with fire-safe procedures and responsibly recycled.

What's included

  • High-capacity cell meeting or exceeding OEM mAh rating
  • Cycle count and maximum capacity diagnostics
  • Abnormal current-drain (parasitic drain) testing
  • New battery adhesive for a secure fit
  • Swollen-cell handling with fire-safe procedures
  • Responsible lithium-ion recycling
  • 30-day parts & labor warranty

Process

How the repair works.

No appointment needed. Here is what happens after you walk in.

  1. 1

    Battery health check

    We read cycle count and maximum capacity and test for drain caused by other components.

  2. 2

    Safe removal

    Adhesive strips are released without puncturing the cell, avoiding the risk of thermal runaway.

  3. 3

    New cell installed

    A high-capacity battery is fitted, connected, and secured with fresh adhesive.

  4. 4

    Charge & load testing

    We confirm stable voltage under load, normal charging temperature, and accurate battery reporting.

When to visit

Signs you need a battery replacement.

  • Maximum capacity below 80%
  • Shuts down unexpectedly above 20%
  • Slow performance or throttling warnings
  • Phone gets hot while charging
  • Swelling, a lifted screen, or a bulging back

Terms

What our technicians mean.

mAh (milliamp-hours)
A measure of how much energy a battery can hold. Higher mAh generally means longer time between charges.
Cycle count
How many full charge cycles the battery has gone through. Most phone batteries are rated for about 500 to 1,000 cycles.
Maximum capacity
How much charge your battery holds compared to when it was new. Below 80% is the usual point to replace it.
Thermal runaway
A dangerous overheating chain reaction in damaged lithium batteries. It's why swollen batteries should be replaced right away.

Questions

Battery Replacement questions.

Still unsure? Call your nearest store and a technician will help.

If your maximum capacity is under 80%, your phone shuts down unexpectedly, or it won't last a day, a replacement will restore full performance. We run free diagnostics to confirm before any work.

Often, yes. Worn batteries can't supply peak power, so phones throttle the processor to stay stable. A healthy cell lets your device run at full speed again.

Yes. A swollen battery is at risk of thermal runaway. Stop charging the device and bring it in; we remove swollen cells using fire-safe procedures.
