What ProCharge does now
Repair what can be saved. Develop what the market is missing.
The work is focused on practical battery problems: packs that fail early, discontinued or unavailable replacements, and applications where off-the-shelf options do not fit the job.

A development-first company
Built around the pack—not the parts counter.
ProCharge is being developed as a technical battery company. The goal is not simply to sell replacement packs, but to understand failure modes, evaluate repairability, and build better-fit solutions for the applications that need them.
Independent repair
Common platforms. Individual evaluation.
Battery condition, electronics, enclosure damage and cell failure vary from pack to pack. ProCharge evaluates the specific battery rather than promising a one-size-fits-all repair.

Repair process
From failed pack to informed decision.
- Identify the battery platform and reported failure.
- Evaluate whether the pack is appropriate and safe to inspect.
- Determine repair feasibility and development options.
- Discuss the path forward before substantive work proceeds.
Lithium battery safety
Damaged batteries need careful handling.
Do not open, puncture or attempt to repair a lithium battery pack yourself. Packs that are swollen, crushed, wet, burned, unusually hot or physically damaged require special handling. Contact ProCharge before transporting or shipping a questionable battery.
Contact before transportHave a battery that failed—or a battery idea that does not exist yet?
Start with the platform, the symptoms and what you need the pack to do. ProCharge will help determine whether the next step is repair, development, or a different solution.
