Merry Christmas to you too. Thanks alot for your feedback.

You r right. Thanks alot for ur help

@@drcheongtv thank you man, to charge the AGM I chosen the mode 2 (12v and AGM), it's very simple but for the beginner is complex to make sure all is right, checked your video again to see how it's gonna blink when fully charged

Ya, i captured the video so i can view it again in future.. Coz not frequently use it, so might forget.. Lol

Your most welcome

Thanks alot for the feedback aidil

Tq for the support bro

But i do hear before that faulty battery is not chargeable. Thats y i also bought a battery jumpstarter so i can jumpstart the car n drive to nearest battery shop to confirm on the battery health.

Introduce u another great product to have, the jumpstarter kit tat i keep in car. Slightly bigger than our power bank but very useful when come to jump starting a dead battery middle of the night.

I see this video and I get c7 for my W205 unfortunately is not work for my battery,maybe is time for me to change a new one

Yes, if the battery is too old and totally faulty, it will not work but it definitely work for battery that drain off due to not in use for certain time.

Tqvm for ur support too

Ya, it took very long if the battery is totally drain.

Beatit B10 Pro power bank for car battery is also another great things to have. It allow us to jumpstart dead battery within 1 min.

U r right, i remembered seeing this in the user manual. Thanks for the reminder friend.

Your most welcome

Wow.. Thanks for the details advise given..

I didn't do that coz i keep everything in the box. Only take it out when i need it. If you frequently use it, then u should. More convenient

I have used R mode as well, yes it took me about 7 hours to complete the entire process 100%. If stuck for over 24hrs, most properly ur battery no longer chargeable. Otherwise, did u try to redo again from start? Or worst case, spend RM10 and let the shop to charge for u. If chargable, means ur batt still in good condition, then maybe ur power source is not strong enough or the steps is not done correctly, do read the manual again. For the R mode, u need to unplugged the battery from ur car.

Dr Cheong TV thank you for your reply. The battery is disconnected from the car while charging. I am going to give it another try tomorrow. Thanks

Your welcome Nicholas. All the best

Tq for ur comments, i didn't do that for normal charging. But if you want to use Regenerate functions, i will advise to remove the battery out from the car and charge it

@@drcheongtv meaning for normal charging no need to remove the existing car cable to the batt ya?

You are right, no need remove from ur car. If you do that, your car electrical settings will be reset to default. Hence, no need remove from car, jus charge directly.

Tqvm for your recommendation. I agreed with you..

Hi, r u referring to Car Fuse?

Thanks for your question. As i understood, fully charge battery will have 48amps. I doesnt matter the output of amp from the charger bcoz if the charger output is 1amp, then will need 48hours to full charge a flat battery but if output is 2amp, then will need 24hours. This Bosch device will automatically cut off the charging once is full. I guess this will not harm the battery. Jus my opinion. If need to confirm, will need to call Bosch manufacturer. Tq and stay safe ya. Tqtq

Yup, this will happen when your battery is drainned off/totally drianed off for too long. Hence C7 unable to detect it as car battery. You need to remove the car battery from the vehicles and use the Adapter mode of ur C7 to push in some charges, after 30min to 1hour, you will be able to select the charging option you need..try view my another videos using below link.

@@drcheongtv Many thanks for your quick response. My car is equipped with Start/Stop function, so I'm not allowed to remove the car battery from my vehicle (My car user manual states that removing a battery with Star/Stop function can be done only by a professional person). So here my further question, can I use your method with the battery still connected to the vehicle ?

Hi Eric, personally i hav not tested the adapter/power supply mode directly to the battery attached to car. If you try it, i will advise you just do it for 30mins and later switch to normal charging. Below is the info i copied from bosch user manual. Mode 3 | Back-up mode /Power supply unit Back-up mode Suitable for providing back-up. On certain vehicles it is essential not to disconnect the vehicle electron- ics from the power supply on battery replacement. In such cases, the C7 can be used to power the vehicle electronics whilst changing the battery. Connection to battery in vehicle Press the mode selection button (8) to select Mode 3 and the LED (14) flashes. Note: In back-up mode, switch off all electrical equipment (e. g. ignition, radio, lights). Note: In back-up mode, as soon as the circuit is interrupted , the charger switches automatically to standby mode. Caution: To avoid possible destruction, never charge the battery for a lengthy period in this mode. Power supply unit Without connection of battery Keep the mode selection button (8) pressed for approx. three seconds. The supply LED (14) will light up as soon as the integrated switch is triggered. Power is supplied at a level of 13.6V (±0.25V)/5A (±10%).

@@drcheongtv I see. I'll try this, and will let you know the outcome. Thanks again for your advice.

Hi Phu Le, if a healthy battery, it won't be drain off so fast. My car battery can only last me 12 to 16 months only. After 12mths, we cant really full charge it. Logically if ur battery is good, once u start ur car, it should auto recharge it. I will suggest u to replace the battery and monitor, if still happen, means ur car is leaking power some where, need mechanic to check.

I will suggest u to get a battery jumper, at least when ur car die off middle of the road or in car park, u can jumpstart it by urself. Below is the video. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-XwTkofPAHjs.html

@@drcheongtv Thank for your reply. I sent it to technical check but seen like no problem detected. battery keep run out, I think I will replace it and see how.

Hope u find the root cause soon. Honestly, now the battery is not as lasting as last time.

Hi Neoh, my one still able to run till now. Touch wood

@@drcheongtv tq for your reply, will purchase and try it out for my car when it flat too. Replacement is expensive rm 1200 per battery 😅

I will suggest you to sent the battery to any mechanic shop and ask them for a full recharge. I think they will charge you for RM10. After full recharge, ask them to test it. They should hav device to test the battery. Coz Bosch battery charger cannot revive or improve the existng battery conditions.

Hi Mark, i hav not tested it b4 but logically should be possible if you hav charged they battery to certain voltage. But you will need power source from home to charge your battery.. So not able to use as jump starter when you outside. I suggest you to try explore Beatit JumpStarter. Super efficient. You can watch the video below

ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-XwTkofPAHjs.html

Thanks for your comment. It can be use to continue charge 1 unit at a time. It means you will need to complete 1 unit b4 moved to next.

How is it products

One time how many batary will be charged

One time how much batary will be charged?

Hi Rakshith, 1 time 1 battery and you need to plug to a power point.

Actually both Bosch C7 or C3 battery charger can directly charge ur car battery without removing it out from the car. If u remove it, u will lost your car settings due to no power. The only diff is C7 can charge biggger capacity battery that up to 24v while C3 only max 12v....small lorry will need 24v otherwise normal sedan car just need 12v

@@drcheongtv thanks, do i need to put it on adaptor mode or R mode

Adapter mode is to continue give electricity to ur car while you replace the car battery and R is for regenerate total drain or dead battery but if you use R mode, you will need to unplug the battery from ur car coz R mode will cause a sudden spike of voltage to ur dead battery hopefully can revive it. If u use R mode when ur battery still attached with ur car, the spike of voltage might burn ur car circuit board. I think best you charge the battery as normal without need to select any mode. Just attached it to ir battery and press the middle On button 1 time, it will turn on and start charging ur car battery. With this method, u do not need to unplug ur battery from the car.

Sorry bro, i dnt have CTEK with me but i saw from you tube, this guy provide details review of CTEK, maybe you can take a look ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-XjaAksjNARs.html

There is a function to charge fully drained battery but need to unplug the battery from the car to charge. BUT you cant charge a problem battery. Some battery when is too old, u cant charge it anymore.

ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-XwTkofPAHjs.html

If you unsure, i will suggest you to buy Beatit Jump starter battery. You jump start the battery using it, once started, let it continie run 15mins. If the battery is good, it will auto charge by the car. If it wont auto charge, mean ur battery is spoil and need to be replace

Unfortunately no.. This is purely for car battery charger.

This unit charge 12v and 24v battery

Hello..if the car is off, the battery should be around 12.4 to12.9V. If engine is on, reading should be 14 to 14.5V..so after fully charged and you still cannot get this reading, most properly is the battery issue

The battery completely drain and I disconnected it from the car I use C7 to charge it but the multimeter reading is 12.58 v I think the C7 should give 14V++

I hav similar issue, it was my battery faulty where it unable to charge with C7. Hence keep on showing 12V+. Not sure which country you are from? If in Malaysia, you can bring to any car mechanics shop to perform full charge. Most properly they will charge you RM10/charge. If still show 12v+ mean is the battery faulty

I'm at Malaysia now the battery is new 4 months old. made in Thailand and I use it very little like 1 day per week only

Oh, if jus 4 month old, should claim for replacement coz all battery come with 1year warranty. 4month old battery should not be showing 12.58v

Thanks for ur question, as I know, Bosch C7 can use to charge wet cell, dry cell, gel type, AGM battery But cannot charge lithium ion batteries. So answer is No.

Hi Kushairy, unfortunately it cannot be use for jump start. Please visit below link, Beatit is extremely good for jumpstart. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-XwTkofPAHjs.html
