When your lithium battery fails—whether it’s not charging, showing 0 volts, or simply underperforming—you’re often faced with a tough choice: replace it entirely or get it repaired.
While buying a new lithium battery may seem like the easier route, the truth is: it’s more expensive, riskier, and often unnecessary. At UpFix, we offer an alternative that’s not only cost-effective but also smarter and more sustainable.
Here’s what makes UpFix different—and why thousands of customers choose us over a replacement.
1. We Repair the Root Problem, Not Just the Symptom
A new battery may seem like a fix—but it doesn’t address what went wrong with the original. In many cases, it’s not the entire battery that’s bad. It’s the Battery Management System (BMS) or one or two out-of-balance cells.
At UpFix, we use precision diagnostic tools to identify the real failure—then we fix it at the source. That means:
-
Rebalancing cells
-
Replacing faulty BMS components
-
Updating firmware
-
Repairing wiring and terminals
-
Full safety and load testing
This ensures you don’t experience the same issue again just months later.
2. You Save Up to 80% Compared to Buying New
New lithium battery packs—especially for EVs, e-bikes, or high-end vehicles like Porsche, BMW, Tesla—can cost thousands.
UpFix repairs usually cost a fraction of that price, with most repairs completed for under $500. Plus, you save on programming, dealership labor, and installation fees.
3. You Keep Your Original Battery—No Compatibility Issues
When you buy a new or used replacement battery, you're often forced to reprogram your vehicle or system to accept it. This can be complex, costly, and error-prone.
At UpFix, we repair your original battery—so it returns fully compatible, already paired to your vehicle or device, and 100% plug-and-play. No headaches. No resets.
4. It's Better for the Environment
Throwing away a lithium battery contributes to growing e-waste problems and chemical pollution.
UpFix helps reduce that impact. To date, we’ve kept over 2.3 million pounds of electronic waste out of landfills by repairing instead of replacing.
