absaar 20 amp charger

[tnewson]

Hello,

 

I was just wondering,

 

I have bought an Absaar 20 amp charger from halfords which has a starterboost capability of 180 amps if the battery is flat. Is there any way to modify the charger to constantly put out 180 amps instead of changing to 20amp charge rate?

 

I know there could be problems with over heating or whatever but i am prepared to put some fans into the casing if need be.

 

I was just thinking that there must be some sort of sensor which tells the charger that the battery capacity has reached a certain level, which would tell the charger to change from 180 amps to 20 amps.. There must be a way to turn this off surely?

 

 

Any help is much appreciated!

Hi Tom,

 

I think it's probably fair to say that the number of responses so far to your question is directly proportional to the advisability of doing any of the things that you suggest.

 

(Which is a long winded way of saying I wouldn't touch it, if I were you!)

Are you trying to turn it into an arc welder? :lol:

[tnewson]

Nah, i've already converted a 140amp arch welder into a charger... just fancied a challenge really

Two possible answers, choose whichever you prefer:-

 

1. Yes. Redesign and rebuild the entire circuit to work at 180 amps.

 

2. No

It wouldn't really need redesigning as it can and does put out 180amp charge, i was just wondering about the possibility of fooling it into continuing the 180amp charge instead of changing to 20amps once the battery reaches a certain charge level.

Actually it would. Just trust me on this.

It doesn't "change" to 20amps.

 

The charger never "pushes" 180amps into the battery, the starter motor "pulls" it out of the charger.

For a very short time.
