Would anyone know the basic charging rates of an automatic charger? I'm going to monitor the charging rate on an 80% discharged battery (which is brand new) & don't know what would be considered in the 'normal' range.
Customer was using a faulty battery & was short charging it all day long for about 3 months before the decision was made to purchase a new battery. Old battery never got hot or smelled while charging- no matter how long on charge- new battery gets warm to the touch & smells of rotten eggs. Can't get a straight answer on water usage so I want to monitor it myself.- Not sure of specs- It's a 48V unit- Thanks

What is the the max amp capacity of the charger? It is recommended that the charger amp capacity rating be within plus or minus 10 to 15% (I was taught 10% other say 15%) of the ahc capacity of the battery. I have seen 1000 amp chargers used on 680 batteries & they "boil" the heck out of the charger. The main issue is when the battery is first connect to the charger - there is a 'blast" of amps (aount varies by charger rating) delivered to the plates of the batteries to "clean" any sulphate build up.
Thanks for the insight & I'll be checking out the bulldog website.
Depending on the charger some of the parameters can be changed to fit the battery specs. If you can change the charger settings than the charger amp hour rate should be with in 10% of the battery amp hour rate either way. ie 100 ah battery can have a charger that has an ah rate of 90 to 110 ahs.
That's a 765 a.h. battery and generally finish rate is 5 amps per 100 a.h. so about 38 amps finish rate. I see Bulldog Battery has a whole service manual on batteries, on line.
The battery is a 24-85-19. Is there somewhere I could go on the web to find this info?
You need to know what model battery you have to look up the finish rate (ie 24-85-13)
rogeriwt- I agree- I just want to measure the charging rate to double check the situation & don't know what it should be- Thanks
A charging battery will be warm and during the gassing or finish charge it will smell- it is hydrogen. Not sure how good the old battery was but it is possible that it was so far gone that the charger never went into finish rate. I would check and make sure the amp hour rating on the charger matches the battery.
