Recently my brother-in-law (who was big into antique Chevrolets) passed away and my sister (knowing I have old Allis tractors) gave me his Centech (read "Harbor Freight") model 63045 6/12 volt battery charger. Large battery charger on wheels. Here is the question.... Charger has 2,10 and 40 amp settings for 12 volts. Only 40 amp setting for 6 volts. I want this for my two WD45's and my WC..is 40 amps to much for a 6 volt battery ?? This is way more than the tractor generator puts out.?.? Will this charger do not harm than good on a 6 volt battery?? Thanks for your patience, I know I am not smart on automotive electrics...Dan |

the charger, like a generator, senses battery voltage and determines what AMPERAGE is needed to charge.... Example, : of your battery is discharged to 5 volts, the charger might put out 40 amps to get it back up quickly.. If your battery is a 6.5 volts, then the charger might put out 5-10 amps to get a small boost... I really dont know what your "40 amps" is set at.. That could be the MAX if your battery is down to 5 volts... It could also be 40 amps output at 6.5 volts, but i doubt it. Easy test is to get your battery fully charged, then connect the NEW charger and watch the gauge for 5 minutes.. Normally you will get a short BOOST of 15- 20 amps for a couple minutes, then the charger "SHOULD" back off to 5- 10 amps when it sees the battery is fully charged..... Leaving it on for 5 minutes will not hurt... The OLD GENERATOR charges at 5-8 amps, but that is the limit of the Generator... the battery can take a bit more. ------------- Like them all, but love the "B"s. |

This may not be a good charger to use as a Trickle Charger on 6v... The 40 amp setting would be to get a quick charge for 10- 30 minutes on a low battery.... the 2 amp setting on 12V would be a trickle and could be left overnight. ------------- Like them all, but love the "B"s. |

To me, that sounds like an older charger. 40 amps is a bit much, but it for fast charging it sounds like. That's one of those chargers you only put on the Battery for about 10 minutes or so cause' you'll boil the Battery. Pick yourself up a Deltran Maintainer for your 6V Batteries. It's always better to put a 1.25-1.50 amp slow charge into 6V Batteries. They last longer.....

. Amps n Current are the potential to draw from. Like you have a foot diameter pipe with a quarter inch tap. The big pipe could supply a foot of water but the skinny pipe can only draw a little. .

I bought a "smart charger" (from Amazon), that does either 6 or 12 volt, a couple years ago. I really like it. My problem is that I have one tractor that had an eight volt battery in it when I bought it. I have been using an old 12 volt (manual) charger that I use on it on the slow charge setting. I keep an eye on it and remove the charger when it gets in the 9 volt area.

That was my point about the 2 amp vs 40 amp charge setting... At 2 amps the charger measures the battery and wants it to be 13.8 volts so it slow charges the 12 v battery... When you set it to 40 amps, the CHARGER is set to 16 volts or more... so when it sees a 12.5 volt battery , it goes to FULL CHARGE .. ------------- Like them all, but love the "B"s. |

YEP... My truck has a 200 amp alternator.. If you JUMP a dead truck it will put out a LOT OF AMPS... When the battery is FULL CHARGE, i doubt it puts out 10- 15 amps ..... until you turn on the electric seat, air conditioner, stereo, GPS, head lights, trailer plug, and work the electric windows and mirrors !!!  
My OLD charger actually has a rotary switch to choose the CHARGE... I think one of the selections is 18 V low charge- 12 v HIGH charge ......... another selection is 24 v low charge-18v HIGH charge..

| Thanks guys for the replies! I guess this may be a good charger when I have a dead battery, but not for just maintaining the charge level. My late dad bought these tractors back in the 50's and they don't get a lot of use, but I want to keep batteries up so they are ready if I want to use them. I have been driving these tractors for 70 years and we are both getting old and don't do as much work as we used to..thanks again..Dan |
