Decide fast when a battery repair makes sense and when a full replacement saves money.

Use clear metrics to choose.

Signs Your Battery Needs Replacement

• Check capacity loss of 20% or more, with range falling by 20–40%.

Example: a 500 Wh pack giving 30% less range after 2 years. (Battery University)

• Check charge-hold problems that persist after full charge cycles and diagnostics.

Example: battery drops from 100% to 40% within 15 minutes of riding.

• Check cell imbalance that shows as one module at much lower voltage during discharge.

Example: module voltages differ by 0.2 V or more under load.

• Check failed BMS events that recur after resets or firmware updates.

Example: BMS cuts power at 60% SOC repeatedly.

• Check physical damage like swelling, leaks, or crushed cells.

Example: pack bulge of 5 mm on the casing or puncture marks.

• Check cycle count above expected life for chemistry type.

Example: NMC packs often degrade significantly after 400–800 cycles (Battery University).

• Ask: does the battery hold warranty coverage?

Example: warranty period of 12–24 months can cover a replacement (manufacturer policy).

Cost-Benefit Decision Checklist

• Calculate remaining useful life in cycles and percent capacity.

Example: 300 cycles left at 70% capacity.

• Calculate repair cost for cell/module swap or BMS repair.

Example: cell-level repair $60–$150; BMS repair $80–$200.

• Compare replacement price for equivalent capacity and chemistry.

Example: 500 Wh OEM $350 vs third-party $250.

• Include installation and testing fees.

Example: dealer labor $50–$120.

• Include disposal or recycling fees if replacing.

Example: recycling $10–$30.

• Check warranty extension or transfer options on a new pack.

Example: new pack warranty 24 months.

• Ask: does repair restore at least 70% of original range at less than 40% of replacement cost?

If yes, repair often makes sense. If no, replace.

• Compare total cost per remaining year of useful life.
