TAGLab C4 Battery Charger (Automatic)

This was a lifesaver for me. During lockdown my bike's battery had deteriorated and it was loosing charge pretty fast so after every one or two weeks it used to drain and go below required level to start the bike. Local battery shops use to charge 100 - 300 to pick up, get it charged and delivered but getting them to do this was a headache. New Two wheeler battery of any make and model were out of stock and still is. I bought this and charged my bike battery 4 - 5 times.Very simple to use, clamps and wiring are good. The adapter/charger itself is very slim but sturdy. Proper alert leds to guide users. Only thing is my bike battery wasn't in good health and wasn't able to store the charge for long but still it didn't give any error to that and got it charged fully. Probably it only shows battery error if the battery is beyond charging capability. It took around 2 - 3 hours perhaps to charge my 12 V 9 AH 2 wheeler battery.

I was in a dilemma to buy this or Bosch C3 charger,but I went with this as the seller had assured that even if the voltage drops less than 10v for 12v battery it can recognise and charge it which C3 Bosch charger was not able to do.I charged 12ah (Royal Enfield, Harley Davidson bikes typical battery capacity), 45ah (mid size petrol car), which are 12v batteries, to be frank they are more than 12.3v which I checked in multimeter and the batteries were less than 1yr old , it charged well, and the light turned green (full charge)Now I tried charging 60ah 12v (diesel car battery generally has high capacity) battery with this charger which is 3 yr old and is also in above average condition (12.3v reading on multimeter which is good reading and performance is fine). It took 38hrs to show full charge on the charger, I don't know if it is problem with the charger or if it is due to it being an 3yr old battery. Also charger is getting hot pretty fast early into the charging and then stays warm to touch late into the charge. Overall for bike batteries it's amazing for petrol cars its good, but for diesel cars with large capacity batteries you better buy c8 charger as it charges with higher currentMy suggestion is to get a cheap multimeter and check your battery regularly. It should be above 12.4v if less u can charge with this chargerBuilt quality is very good, I think its a good buying choice if you are leaving you vehicle unused for long period of time

Bad quality, customer care number not working. Don't spend money on it.

Till now this charger is used many times including friends, neigbours & is still performing as it should.IP65 enclosure makes it drop proof & sturdy.It is almost same as the Bosch C3 battery charger which my colleague has, but with higher 9- stage automatic charging process & low threshold voltage due to which it can recognize batteries with very less residual voltage for recharging unlike the Bosch C3 & other chargers.Voltage selector 6V / 12V switch eliminates the error in validating the correct rating of batteries with less residual voltage.It is sold by the company itself unlike other chargers sold by only-for-Amazon retailers.Hence, the after sales call-in support process is smooth & good.Overall, great value for money charger.

I bought this charger for home use after discarding an unbranded one bought here, which did not work. I bought this in comparison with the Bosch C4 charger which was clearly more expensive. This caught my attention as it was Made in India. The package arrived on time, very well packed and I immediately put it to work on my 12v inverter battery which was dead for over 2 years. Next, I charged a 12v motorcycle battery. Both applications worked very well. A really good feature on this is you can manually select 6v or 12v which is not possible on the Bosch. As a result, if your 12v battery is very low the Bosch charger reads it as a 6v batt and does not charge it properly. Here you can manually select the battery voltage. The build quality is excellent with LED lights for ON, Charging and Fully Charged. I would rate this better than Bosch. It also comes with an extra lead which can be used to charge bike a battery without removing it from the bike. Highly recommended!

Working fine but there are 2 problems I noticed.1. I heard that it makes some peculiar sound while charging battery 6v/12v.2. After charge completion of the battery isn't removed for sometime, let's say for 5 minutes then it starts charging again.Without wasting any time I just removed the battery. Not sure whether it will deteriorate the battery.

The media could not be loaded. First let me describe about the car battery I charged with this charger.The car battery I charged was of Lead acid type. The battery was not fully dead as I was able to use the headlamps,parking lights,fog lamps,music system,wiper with my battery power, however battery was not generating enough current to start the car, that was the only problem.I connected the terminals of the battery with the charger and after main power is switched on the battery starts charging. As the charging started, the LED indicating "Power" and "Charge" was lit. So far so good.I thought that battery will get fully charged after 4 hours because the battery was not fully dead as I explained in the beginning. To my surprise the charger was charging the battery even after 28 hours, which is a very long time period considering that battery was not fully dead.At the end of 28 hours, the "Full battery" LED didn't light up, which is very disappointing. I removed the charger from the battery. After that I start my car and it got started.The only thing which I don't like about it is either the product is faulty because after 28 hours of operation the battery is not fully charged or the manufacturer under quoted the capacity of the charger.
