WHY DO THEY HAVE DIFFERENT WARRANTY PERIODS FOR BATTERIES?


Average battery life has become shorter as energy requirements have increased. Only 30% of batteries sold today reach the 48-month mark. In fact 80% of all battery failure is related to sulfation build-up. This build up occurs when the sulfur molecules in the electrolyte (battery acid) become so deeply discharged that they begin to coat the battery's lead plates. Before long the plates become so coated that the battery dies.

Modern batteries have better internal constructions and content additives to extend battery life.

For example, The Absorbed Glass Matt construction enhances both the discharge and recharge efficiency .Modern batteries already include additives that reduce sulfating and corrosion.
For example Calcium replaces antimony in the plates of the battery to give it some advantages including improved resistance to corrosion, no excessive gassing, less water usage and lower self-discharge. Silver is another additive used by some manufacturers, the addition of silver enables the battery to be more resilient to high temperatures.
Depends upon the internals, the life of the battery, cost and warranty period varies.

Don’t be carried away with the length of warranty. Understand the base and extended warranty period before buying. There are some better brands are in India which gives you the maximum life period @ a price like TATA GREEN Gold XT, EXIDE Matrix & AMORAN Pro.


BASE WARRANTY & EXTENDED WARRANTY


LENGTH OF WARRANTY - Your warranty begins the day you purchase the battery, and expires at the end of the warranty period.

FREE REPLACEMENT PERIODS - Your free replacement period begins the day you purchase the battery, and expires at the end of the "Free Replacement Period" When a battery is replaced during the "Free Replacement Period", the warranty does not renew, it continues on from the original date of purchase.

PRORATION- The prorated purchase price of any battery listed above, which becomes defective after the lapse of the "Free Replacement Period", and prior to the end of the warranty period, will be either credited toward the purchase of another battery, or refunded at option. The amount of the proration shall be determined by dividing the purchase price by the number of months of the warranty period, and then multiplying the result by the number of months remaining in the warranty period. (Any partial months will be rounded to the nearest whole month). When a battery is replaced after the "Free Replacement Period" and a prorated fee is paid, the warranty starts from that date as a new purchase.

Hello Mudhanji,

Today I was testing my battery to check how much juice it has before replacement. So the story started about a month or so. We wanted to go out for shopping so as usually I went first to start car but before my wife could come out of gate, raining started a lot so she stayed at home for 30min and I was enjoying music(amp+basstube) and suddenly everything stopped and I couldnt start car. Then I realized well battery died as cracking wasnt strong enough to start car. So I called up road side assistance and they came up to jump start my car. (That guy told me lots of calls from customer today due for same reason battery issue)

I asked to check my battery health in recent service, got call from SA saying it needs to be changed. So before changing I thought I will test how much it shows using OBD-II scanner (on my mobile using torque).

Before start/ACC mode - 12.9v
After start/engine running - 14.5v (without other accessories running)
After start/engine running with all accessories 12.9 - 14.4v (started head lights, DRL, HU Unit, Amp, Basstube, doom light etc)

I do feel battery doesnt has that much cracking power which it use to have when new. Also my car running is not that much means in weekend 10km or in month 200km max. Now question is above readings are ok? average? Should I change battery? Should I wait for few more months?

As my upcoming trip to Mumbai(from Delhi) is near I am in dilemma should I change or it will be fine in after running 3500km? Also winter season is coming so I m not sure this battery will start car.

If I have to change battery I would surely go for Amaron AAM-PR-00050B20L(same battery you installed in Albus) and will buy from BatteryBhai.com - India's No. 1 Online Car/Inverter Battery Store they are selling for Rs. 3459/-

Hello @kuwaronline

Can I know how old is your car is and how much is the odometer?

I think you have taken voltage right after turning off the engine so its on higher slide.

Its better to take voltage measurement using voltmeter connected directly to battery and before even putting car keys because there will be least power used by car electronic system. Measurement should be taken in the morning when the car is idle for whole night. Its even better if you unplug the battery and measure the voltage so it will be 100% accurate.

Now that SA has said battery has to be changed, did he gave you battery testing report slip?

Faulty batteries usually be in good voltage ratings but fail when engine is cranked. They drop below limit and you will notice lack of cranking power. To test this connect voltmeter to battery and crank the engine. If the voltage drops below 9.6 then its time to change the battery.

Whatsoever it be, if you have doubt about the battery and need peace of mind, its better to buy a new one. That's what I did when my battery gave trouble. I could get it working but still don't want to take risk so bought a new battery. [:)]

Thanks...
Best Regards

Hi CRACING,

My car is almost 3 years old now. Odo is nearly 20k.

I dont have volt meter but I will get it checked by battery shop soon. SA didnt showed or gave me slip. My car was idle for atleast 4-5 days before taking these results. But I will check again after few days as you suggested.When I cracked it didnt go below 12v I quite sure but I will check again. If it goes below I will surely replace if not then I will wait for few more days as winter already arrived in Delhi NCR. May be in mid Nov I will see result as winter is quite harsh here. Which battery you have installed?

Thanks for quick reply!

OK

My new battery starts from 12.5 +/- 1v when checked with voltmeter and through OBD, its 1-2v less due to some load.

Here is the chart of Battery Voltage and State of Charge:

12.7v .............. 100%
12.6v ............... 90%
12.5v ............... 80%
12.4v ............... 70%
12.2v ............... 60%
12.1v ............... 50%
12.0v ............... 40%
11.8v ............... 30%
11.6v ............... 20%
11.5v ............... 10%

*Open-Circuit.

Source: Trojan Battery Company

Other sources mention slightly different state of charge (SOC) for voltages below 12 but you get an approximate idea.

My new battery is Exide Mileage 35ah and had installed 6 months ago. Bought for Rs. 3850 in exchange of old battery (Rs. 500). Old battery was Amaron which severed for 5 and half years and 48k KMs.

Thank you Cracing,

I did checked once again and yes my battery voltage drops to 8.9v while crancking. So yes my plan is to change is next month before my long trip to Mumbai.

I m getting Amaron with 60 month warranty @3449/- with exchange of old battery and that guy will come at home to install.

Thanks Again!!!

Dear All,
I would like to request help from experts for finding one new battery for my Sonata Gold
I got one quotation from local dealer for Amaron 90D 23L – Rs 5000/-
Is it good rate? The battery is perfect for Sonata?

In recent service of my car (Honda Brio) I asked technician to check battery status and learned that it has voltage of 12.3V on full load. So is battery in good condition or will need replacement very soon ? Car is 3 years old.

bhvm 7th December 2015 10:34 AM

Re: Guide: How To Make Your Car Battery Go On & On!
 
12.3v with engine running is not a good sign. it should be Atleast 14.2v. healthy voltages are 14.4v to 14.8v

Small correction, I got Amaron Pro battery for 3200/- (Not 3449/-). That too home delivery and installation. (Gurgaon)
