Start with a diagnosis and a written scope
“Battery replacement” can refer to a complete pack, a refurbished assembly or a limited repair. These are not comparable purchases. Ask which fault or test result motivates the proposed work, what parts are included and whether the proposal replaces the whole battery. A price without a scope is not enough to compare suppliers.
Ask for an itemised total
Separate the battery or repair quote, labour, transport, diagnostics, tax and other charges. Clarify whether the supplier retains the original pack, whether a core deposit is refundable, and whether software work is included. Avoid adding tax twice if a quote already includes it. If a charge is unknown, leave the comparison incomplete rather than filling the gap with a convenient estimate.
Compare terms as well as numbers
New, refurbished and used packs can come with different histories and warranty conditions. Ask about compatibility, documented condition, who carries out the installation, and what happens if a fault appears after fitting. Get the warranty period, exclusions and responsible business in writing. A price per kWh is only a rough normalisation for a complete pack; it does not compare the value of a partial repair.
What the EVVerity calculator does
Enter the actual quote and the known additional charges. The tool adds them and, for a full pack, divides the pack price by the capacity you supply. It does not source a live market price or claim that the quote is competitive. If you do not have verified price evidence, the honest result is that verified replacement-price data is unavailable. These are our quote-comparison steps, not a manufacturer price list.
Use a like-for-like quote sheet
Ask each supplier to fill the same categories. “Included” and “not quoted” are different answers. A missing charge must not quietly become zero in a comparison.
| Quote item | What to clarify |
|---|---|
| Pack or repair | Complete assembly, module work or another component? |
| Installation | Labour, diagnostics, commissioning and software included? |
| Old battery | Core return, refundable deposit and transport terms? |
| Tax and warranty | Tax included, written cover and responsible provider? |
A worked quote, without a market-price claim
Imagine a written pack quote of 8,000 currency units, labour of 900 and transport of 150, with tax already included in those amounts. The arithmetic total is 9,050. For a complete 60 kWh pack, the pack-only quote is 133.33 per kWh; the all-in total is not the same metric. These figures are invented solely to demonstrate addition and division, not to estimate an EV battery’s actual price. If a core deposit is refundable, show the cash required initially and the expected refund separately. Do not use a full-pack price-per-kWh comparison to rank a partial repair.
Before you rely on the answer
- Are you comparing the same repair scope?
- What remains payable if the diagnosis changes?
- Who handles a warranty claim after installation?

Electric car battery cost: what price are you comparing?
A small auxiliary battery price, a traction-battery module repair and a complete installed high-voltage pack price describe different jobs. A battery-manufacturing cost per kWh is also different from a retail replacement quotation including diagnosis, fitting and tax. Ask which figure the headline represents before using it in a budget.
The US Department of Energy notes that manufacturers typically do not publish replacement battery prices. EVVerity therefore uses your verified quote instead of assigning a universal price to every model. Keep the quote date, currency, exact vehicle, pack condition and included work together. Battery age alone does not establish that replacement is needed.
| Quoted amount | Check before adding it | Avoid |
|---|---|---|
| Pack or repair price | Whole pack, module, component or auxiliary battery? | Treating every battery price as comparable |
| Installation and diagnostics | Included in the main quote or separate? | Counting bundled labour twice |
| Tax and delivery | Gross/net basis and applicable delivery charges | Adding included tax again |
| Core deposit or exchange | Refundable conditions and who keeps the old pack | Treating a refundable deposit as a permanent saving |
| Warranty | Written scope, responsible supplier and exclusions | Assuming every new or refurbished pack has the same cover |
