What your battery warranty actually asks of you

Most Indian EV owners worry about fast charging. Their maker's documents worry about other things, and say so in writing. Pick your vehicle and this shows the rules your own maker states, word for word, and then what the published research says wears a pack down.

Answer all six and this shows the rules your own maker wrote down, word for word, and then what the published research says wears your pack down, ranked for the answers you gave.

Honesty

What nobody knows

no numberNobody has published a capacity loss figure per fast charge session. Any tool that turns four sessions into a percentage invented it.
disputedOn 22,700 vehicles, heavy fast chargers lose about 2.5 percent a year against 1.5 for light users. On 13,000 Teslas, over 70 percent fast charging against under 30 showed no significant difference. Both are real studies and they disagree.
not indiaThere is no published field measurement of EV battery degradation in India. WRI India says so in its own working paper.
not measuredThere is no standardised way to measure a vehicle’s state of health. The number a service centre reads comes from the maker’s own model.
not adviceThe rules above are quoted from maker documents and are not a legal reading of your warranty. Check your own manual and policy before you rely on them.

Every rule on this page is quoted from a document published by the maker and recorded in our open datasets with the document it came from. The research is drawn from the studies above, all of them measured outside India. This is not a measurement of your battery and it cannot predict its life.
