The Tata Punch battery size to buy is the one that matches the Ah rating, case size and terminal layout printed on the 12 volt battery already fitted under the bonnet of your car. We have not printed a single Ah figure because the maker's rating did not turn up in two independent sources, and copying the label off your own battery is the most reliable way to get it right.
Petrol and CNG cars use one 12 volt lead acid battery to start the engine and run the lights. The Punch EV also has a small 12 volt battery that powers the lights, locks and screens, separate from the large traction battery under the floor. This page explains how to read the label, what to tell the parts shop, and the signs the battery is near the end.

Where to find the Tata Punch battery size
Open the bonnet. The battery sits in a tray at the front of the engine bay. Its label shows:
- Voltage: 12 V on every Punch.
- Capacity: a figure in Ah, the amount of charge it can hold.
- Cold cranking amps (CCA): how much current it gives on a cold start.
- Case code: a size code that tells the shop the box dimensions and terminal side.
Take a clear photo of the label before you go. The owner's manual also lists the battery in its technical data section, and the dealer can read it off your VIN.
Petrol, CNG and EV differences
| Version | Low voltage battery | What to check |
|---|---|---|
| Petrol, manual or AMT | 12 V lead acid under bonnet | Ah and case code on label |
| CNG | 12 V lead acid under bonnet | Same; the car starts on petrol so cranking load is similar |
| Punch EV | 12 V auxiliary battery | Dealer fit advised; tied to the EV system |
Cars with idle start stop, where the engine cuts out at signals, put more load on the battery. If your Punch has this feature, the replacement should be at least the same type and rating as the factory one, not a cheaper lower grade.
Signs the Punch battery is weak
A slow, dragging crank on the first start of the day, a clicking sound with no crank, headlamps dimming while you crank, or the start stop system refusing to switch the engine off at signals all point to a tired battery. White or green powder round the terminals is corrosion and causes poor contact. Many batteries last a few years in Indian heat, and less if the car stands unused for weeks. Most parts shops will test it for free with a load tester.
Replacing it yourself
- Switch everything off and remove the key.
- Disconnect the black negative terminal first, then the red positive.
- Undo the hold down clamp and lift the battery straight up; it is heavy.
- Clean the tray and terminals, fit the new battery the same way round.
- Connect positive first, then negative, and tighten the clamp.
After a battery change, power windows may need their one touch function reset and the radio may ask for setup. On an EV, have the dealer do the job, as the 12 volt circuit links to the high voltage system.
What to say at the parts shop
Give the model, fuel type and transmission, show the photo of the old label, and ask for the same Ah, the same or higher CCA and the same case size with terminals on the same side. A battery that is too tall can short against the bonnet. Ask for the date of manufacture on the new battery; avoid stock older than a few months. Hand in the old battery for safe recycling, as it contains acid and lead.
Battery care in Indian conditions
Heat is the main enemy. Choose shaded parking where possible, keep the terminals clean and tight, and drive the car at least once a week for 20 minutes so the alternator can top it up. During long monsoon spells, when the car sits wet and unused, a weak battery is the first thing to fail. Extra loads such as aftermarket fog lamps or high power horns should be wired with a relay so they do not drain it; see Punch fog lamp for more. Our battery size chart lists other cars, and the Punch tyre size page covers tyres.
Questions owners ask
What is the battery size of the Tata Punch?
It uses a 12 volt battery. Match the Ah rating, case code and terminal layout printed on the label of the battery fitted to your car.
Is the Punch CNG battery different from the petrol one?
Both use a 12 volt lead acid battery under the bonnet. Read the label on your car, since the fitted battery can vary by version.
Does the Punch EV have a 12 volt battery?
Yes. Besides the large traction battery, it has a 12 volt battery for lights, locks and screens. Get it replaced at the dealer.
Can I fit a higher Ah battery in my Punch?
A slightly higher Ah in the same case size is fine and gives more reserve. A bigger case may not fit the tray or may touch the bonnet.
How do I know my Punch battery is dying?
Slow cranking in the morning, clicking, dim lights while starting and start stop not working are the usual signs. A load test at a parts shop confirms it.
