hi,
i have got this charger what works off 240v (mains) and it is a 310amp charger what chargers car batteries to full in about 5mins now i need to know if hawkers would be ok being charged by it
a picture of the charger is on my profile
thanks
kenny
abit dirty but works fine
btw its not a car battery charger its a universal charger what chargers everything
i will bring tomorrow to stoke if you want a look?
you see the 2 black contectors at the top the left one is 12v and the right on is 24v so it can charge 12v or 24v at 310amp
my dad says a 16ah hawker on boost thats 310amp it would charge the hawker in about 11 seconds as it it takes a car battery 12secs to start to boil
would charge the hawker in about 11 seconds How hot you reckon that batterie will get!?
Ive just got my hands on some old wheel chair chargers...there 6amp chargers that i think alot of other people use, try and pick up two of those. Or you will kill your batteries.
ill bring it tomorrow to stoke so all you can have alook at it
There should be no problem charging a Hawker at that current. Their internal resistance works like a current limit and prevents them from exploding no matter what current you supply to them.
I belive 5C is the maximum current the Genesis and Odyssey will accept. They wont explode if you supply any higher, but it wont decrease the charging time.
Though the only chargers capable of delivering that amount of current is used for forklift trucks, not many other batteries will survive a current like that.
But I suspect that the charger isnt capable of delivering 310A continous, as that would pull over 32A from the mains supply if you were charging a 24V battery. My guess is that its a start booster, used for starting cars with dead batteries. Can supply 310A for a few seconds, and then charge the battery with 20A or so.
does anyone what me to bring it to stoke to have alook?
You should not charge you Hawkers with this charger. This charger got no controlled upper voltage limiter. When the voltage is above approx 14.4V the water will separate into hydrogen and oxygen. It is NOT a good thing in a sealed battery. I know about this. Please don€™t listen to the others guesses. Read the documentation from Hawker first.
If you must try this charger, please do it in a ventilated area (outdoor) and wear protective clothing.
Have Fun

ok thanks i think ill just use a power suppiy
Bulldog uses a 6amp chair charger, which takes 2.5 hours to charge 2 hawkers in series but in between competitions I charge all our batteries separately,@ 3amp, nice and steady ,i could if I wanted charge @ 30 amp but dont want to force feed the bats!!!!!!!!!:proud:
OK, I don€™t know if this particular charger got voltage limitation. I just know that affordable ones (at this current) don€™t have it.
The Hawker can take all current the charger can give as long as the voltage is kept below the maximum allowed. 300A is not impossible but rather improbable. The important thing is voltage control. The time it takes to charge a battery to 100% will always take a long time because the last few percents simply must be slow. You will not gain much by rushing the initial charge.
Have Fun
