Auto battery charge - need your advice

Hi,

In my first post - I might want to ask some assistance for the battery charger in my bike.

As the exposition appears, This auto battery charger circuit can be utilized to charge 12V and 6V batteries. On the off chance that it is utilized a transformer that can convey 4A to 5A at a voltage in the vicinity of 12.6V and 16V then we can dispose of the switch for 6V or 12V batteries. The schematic is given beneath.


It likewise gave some support tip about the auto battery.


The auto battery charging current is consequently constrained to 4.2A. On the off chance that there is a 600mV voltage on R1 (4A through it), at that point, the T1 transistor begins to direct. Inordinate charging current is stayed away from in light of the fact that the present estimation of T3's base is constrained. The distinction between connected load current (at T4's authority) and genuine voltage of the battery are adjusted through T4's gatherer producer intersection. According to the datasheet of 2N3055AG https://www.icrfq.com/part/1926205-2N3055AG.html


The power contribution of 2N3055AG is the result of load current and voltage distinction as of now said. While charging 6V auto battery this power achieves a greatest of 40W. The rectifier diodes must have the capacity to convey 4A at 40V. T4 2N3055 must be mounted on a decent heatsink keeping in mind the end goal to scatter the warmth.


I can't comprehend what byx21-40 is?


1) Is it like a diode rectifier ??
2)and what is 21-40 implies like between 21-40 or simply it's datasheet code (since I scarcely discovered it on google)
3)and if it's being sold similarly as it is and consider the possibility that I didn't discover it in the market.

Can anyone please advise me about my auto battery charger? Thanks to anyone who replies me.
 
You can always just undo the POS battery terminal while using a car charger if you have any doubts. I havent ever had anything damaged though using any off the shelf battery chargers. Im failing to understand why all the concern actually.
 
Sorry, can't answer your questions. I do know though that motorcycle batteries shouldn't be charged faster than 1A flowrate.
 
There is no schematic and the description appears to be translated from some other language than English. a schematic and also a brief description of what you are doing might help.

that is probably true for a slow charge but if you put 14.5v across a lead acid 14 amp-hr battery it will accept closer to 3-4 amps depending upon state of charge.

in agreement with what you are saying, charging currents (running at speed)can have much higher charging rates, but once state of charge approaches 100% the charging current will drop to 1 amp or less.

I did not mean to run you off. At least provide a link to the schematic. Is this a 220VAC charger or a rectifier / regulator that runs off of the motorcycles AC stator?
