How long does an electric scooter battery last?
An electric scooter battery does not die suddenly. It slowly holds less energy, and the range shrinks with it. Most makers and warranties treat the end of life as the point where the pack holds about 70% of its original capacity. A scooter with a 100 km range would then go about 70 km on a full charge.
Two things wear a battery out. Cycle ageing comes from charging and discharging. Calendar ageing comes from simply getting older, and it is faster in heat. A good premium pack is rated for about 800 to 1,500 full cycles, which is roughly 60,000 to 100,000 km or 6 to 8 years. A budget pack with basic cooling may reach only 300 to 500 cycles, or 3 to 5 years. LFP packs trade some weight for longer life, with ratings of 2,000 cycles or more, and they cope better with heat.
How this calculator models battery health
Health starts at 100%, drops about 2.5 points while the pack settles in during the first 5,000 km, and then falls in a straight line to 70%. The line ends when either the cycle life or the calendar life is used up, whichever is first.
Cycles are your distance divided by your real-world range. The defaults are 1,000 cycles and 8 years for a premium NMC pack, 2,000 cycles and 10 years for LFP, and 400 cycles and 4 years for a budget pack. They sit inside the ranges that makers and guides report, and you can type your own. After a replacement the new pack starts again at 100%.
Worked example
A rider on a 3.7 kWh scooter with a 105 km real-world range rides 35 km a day, 6 days a week. That is 10,920 km a year. The battery reaches 70% health after about 8 years, because the 8-year calendar life ends before the 1,000 cycles do. That is roughly 87,400 km and 830 full cycles.
Charging at home at ₹8 a unit and 85% efficiency, the scooter costs about ₹0.33 per km. A petrol scooter at ₹102 a litre and 45 km per litre costs about ₹2.27 per km. Over 10 years the electric scooter costs ₹2,63,216 in total, including a ₹70,000 battery replacement in year 8 (₹75,000 less ₹5,000 scrap), and the petrol scooter costs ₹3,84,520. Electric is ahead by about ₹1,21,000 and stays ahead from month 27.
Now look at the warranty. The standard cover of 3 years or 30,000 km ends long before the battery wears out, so the rider pays. Ather Eight70 (8 years or 80,000 km) does not help here either, because this rider passes 80,000 km in year 7, before the battery reaches 70%. The 10-year plan (10 years or 1,00,000 km) does cover it, and with its ₹8,999 price the 10-year saving rises to about ₹1,82,000.
Battery replacement cost in India (2026)
Authorised service centres quote about ₹19,000 to ₹25,000 per kWh. That is higher than the ₹15,000 to ₹20,000 per kWh that older guides use, so check a current quote. These are estimates from 2026 buyer guides and may exclude labour.
| Scooter | Pack | Estimated price (₹) | Per kWh (₹) |
|---|
The pack is the costliest part of the scooter, often 30% to 50% of the showroom price. Lithium-ion batteries carry 18% GST, so check whether your quote includes it.
Battery warranty: what is actually covered
A battery warranty pays out only when health falls below a set level, usually 70%, inside a set number of years and kilometres. Whichever limit comes first ends the cover. Terms differ by variant and purchase date, so read your own papers.
| Brand | Standard battery cover | Longer cover |
|---|---|---|
| Ather | 3 years (30,000 km) | 5 years / 60,000 km with the Pro Pack. Eight70: 8 years / 80,000 km for ₹4,999. 10-year plan: 10 years / 1,00,000 km for ₹8,999 |
| Ola | 3 years / 50,000 km | Up to 8 years with paid plans of 1,00,000 or 1,25,000 km, depending on the variant |
| TVS iQube | 3 years / 50,000 km (3 years / 30,000 km on the 2.2 kWh) | 2 more years or 20,000 km for ₹4,499 to ₹10,500 |
| Bajaj Chetak | 3 years / 50,000 km | 1 more year or 10,000 km, or 2 more years or 20,000 km |
| Hero Vida | 5 years / 50,000 km | Extended plans up to 60,000 km or 75,000 km |
Charging losses and the true cost per km
The meter always reads more than the battery stores, because some energy is lost as heat. A home AC socket is about 85% efficient, a public AC charger about 88% and a DC fast charger about 94%. Cost per full charge is the battery size divided by the efficiency, multiplied by your price per unit. A 3.5 kWh scooter at ₹8 a unit and 85% efficiency draws 4.12 kWh and costs ₹32.94 for a full charge. Ignoring the loss would show ₹28, which is about 15% too low.
As the battery ages the range falls, but the energy used per kilometre stays about the same, so the cost per km does not rise. You simply charge more often.
Repair, scrap value and resale
If the pack still holds charge but a few cells or the BMS have failed, repair can cost far less than a new pack. Guides quote about ₹8,000 to ₹20,000 for a BMS and ₹15,000 to ₹30,000 for module work, but a repaired pack may come without a fresh warranty. Under India's Battery Waste Management Rules, producers must arrange the collection and recycling of old batteries, and some centres give a credit for the old pack. The calculator uses a cautious ₹5,000, and you can set it to zero. Resale value is not included for either scooter.
How to make the battery last longer
- Avoid running it down to zero often. Deep discharges stress the cells.
- Do not leave it sitting at 100% for long periods.
- Park in the shade in summer. Sustained heat above 35°C ages the pack and can cut range by 10% to 20% while it lasts.
- Use the manufacturer's charger and keep the software updated.
Assumptions and limits
Upkeep is set at ₹1,200 a year for electric and ₹4,500 for petrol, in line with the rule of thumb that a petrol scooter costs three to four times as much to maintain. Real-world range is about 28 km per kWh in the presets, which suits typical city riding. Insurance, loans, registration and resale are left out. Price and policy details change often, so use your own quotes.

Frequently asked questions
How long does an electric scooter battery last in India?
A good lithium-ion pack in a premium electric scooter is usually rated for 800 to 1,500 full charge cycles, which is about 60,000 to 100,000 km or 6 to 8 years of normal use, until it holds roughly 70% of its original capacity. Budget packs with basic cooling may manage only 300 to 500 cycles, or about 3 to 5 years. LFP packs are reported to last 2,000 cycles or more.
How much does it cost to replace an electric scooter battery in India?
Published 2026 estimates range from about ₹45,000 for a 2 kWh pack to ₹1,20,000 for a 5 kWh pack. That works out to roughly ₹19,000 to ₹25,000 per kWh at the authorised service centre. A 3.7 kWh Ather pack is quoted at ₹70,000 to ₹80,000 and a 4 kWh Ola S1 Pro pack at ₹85,000 to ₹90,000. Labour may be extra, so confirm with your service centre.
Is a battery replacement covered by the warranty?
Only if the battery fails inside the warranty and falls below the guaranteed health level, which is usually 70%. Most brands give 3 years as standard: Ather 3 years, Ola 3 years or 50,000 km, TVS iQube and Bajaj Chetak 3 years or 50,000 km, and Hero Vida 5 years. Longer plans exist, such as Ather Eight70 at 8 years or 80,000 km for ₹4,999. The km limit often ends cover before the years do, so check both.
How does the calculator estimate battery health?
Health starts at 100%. It drops by about 2.5 points in the first 5,000 km, then falls in a straight line to 70% when either the cycle life or the calendar life is used up, whichever comes first. Cycles are your distance divided by your real-world range. You can edit the cycle life and the calendar life, or pick NMC, LFP or budget defaults.
What is State of Health (SoH)?
State of Health is the share of the original battery capacity that is left. A battery at 80% SoH holds 80% of the energy it held when new, so a scooter with a 100 km range would go about 80 km on a full charge.
Does the electric cost per km rise as the battery ages?
Not by much. An older battery stores less energy and gives a shorter range, but the energy used for each kilometre stays about the same. You charge more often rather than paying more per km, so the calculator keeps the cost per km fixed.
How much energy is lost when charging?
A home AC socket wastes about 10% to 15%, so the calculator uses 85% efficiency. A public AC charger is about 88% efficient and a DC fast charger about 94%. The meter reads more than the battery stores: a 3.5 kWh pack at ₹8 a unit costs about ₹32.94 for a full charge, not ₹28.
Is an electric scooter cheaper than petrol once the battery is replaced?
It depends on how far you ride. In the default example (35 km a day, 6 days a week, ₹8 a unit, petrol at ₹102) electric is ahead by about ₹1,21,000 after 10 years even after a ₹70,000 battery bill. A rider who covers few kilometres a year saves less fuel, so the higher purchase price and the replacement may never pay back.
Can I repair the battery instead of replacing it?
Sometimes. Replacing a degraded cell string or the BMS can cost far less than a full pack. One guide puts a BMS replacement at ₹8,000 to ₹20,000, and another quotes module repairs at about ₹15,000 to ₹30,000. Type the repair cost into the replacement cost box to see the effect. Repairs may not carry a new warranty.
What is the scrap value of an old scooter battery?
Recyclers can pay for the metals in an old pack, and battery rules in India make producers responsible for collecting end-of-life batteries. Prices are not published in one place, so the calculator uses a cautious ₹5,000. Set it to 0 if you do not expect any credit.
Does hot weather shorten battery life?
Yes. Long spells above 35°C to 40°C speed up ageing, mainly in NMC packs without strong cooling. If you ride in a hot region, reduce the calendar life by a year or two to be safe.
Does the subsidy change my result?
Enter the on-road price you are quoted after any subsidy. Under PM E-DRIVE an eligible electric two-wheeler gets ₹2,500 per kWh of battery, up to ₹5,000, according to an August 2026 report. Rules and dates change, so check with your dealer.
