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?
