I need two used 48 volt batteries - urgently! Send me a private message.

Golf Cart? If so for clarity they're 8 Volt Deep Cycle Batteries (x 6 is 48V Golf Cart) with the others being 6 Volt (x6 is a 36Volt Golf Cart).

Phil - yes - golf cart. I see your math and agree each one would be 8 volt. I've been told it is not advisable to put just two new batteries in and to find used ones if I can.

True...new batteries will "fight" with the old ones and cause premature failure. However if you can't find 2 used then you would be well-advised to replace them all..an expensive move but best in the long term.

What brands are sold and for how much per battery?

I have heard same if you have to by new do them all at the same time. May be costly but better in long run over wearing down 2 new ones against 4 older ones.

I have also heard it is an urban myth. If one of your old batteries is bad it will denigrate the new ones. What happens is the motor draws a certain load or juice, that in theory a set of six batteries can handle. The faster you go the more it draws up to a maximum. If one is bad or low it sucks more juice from the others to make up for the bad one, and so kills the charge (and the life) of all of them quicker. The other problem is that one bad connection in the many of the loop also draws more juice killing them quicker. Thats why all connections must be tight and they're not if you see the green mould growing on connections.

Brands. Trojan T105 (from memory ?)are the suppliers choice ie Club Car. There are some slightly cheaper alternatives too. I have a set of Excide brand in mine. They're horribly expensive - over Bz$300 each.

If you hook an old battery to a new battery and put a volt meter on it , you will see the old battery will draw the power out of the new one . By the end of your test the New battery will have drained to the same voltage as old Battery .
Then take 2 new bats and do the same , you will see the volts stay the same approximately 12.70 volts .. Batteries are expensive ,most people dont know the better the charger the longer your bats will last . It is important not to overcharge or undercharge . Most Cart chargers these days (lestronic )have regulators to prevent this . The Chargers with timers are bat killers . Hope this helps ,if you do test; hook batteries in a bank + to + (positive) and - to - (negative)

WOW - thanks for all the good information. Are you telling me that I need to change the way I charge? When I come home I plug in and leave it until I leave; which may be days at a time. Is this bad? I seem to go through them way too fast.

A great deal depends on the type of charger. In Britain there are the old-fashioned ones that keep dishing out a charging current regardless of the state of charge the battery has reached. These will charge a totally flat battery but must not be left on permanently, as they will "cook" the battery.

The more modern sort is a "smart" charger, which has nothing to do with Ashcroft but is a charger that senses the state of the battery and stops charging when the battery is full. If you leave it on permanently this sort of charger just adds a slight "trickle charge" from time to time, and in fact it's recommended that they ARE left on all the time. These will not however charge a totally flat battery, as they depend on electrical feedback from the battery and a flat battery can't give that.

In theory there could be a yet more modern type of charger that would do both, but I've never heard of it. Maybe someone technical can add something here?

So, if your charger will charge a totally flat battery it's almost certainly unwise to leave it on permanently. Probably the best thing to do is to read the manual that came with the charger, or look up the manufacturer and contact them.

Batteries need to be taken care of ! Adding correct kind of water , and charging correctly will determine the life . The battery water should stay above plates ,but dont fill battery all the way. Get a lestronic charger (automatic), when the battery is 75% full it starts lowering the amperage till it is trickle charging .
Timer chargers stink they are killers , get a lestronic auto. charger(sharks ). Get battery water and keep full above plates, make sure you run Battery LOW every now and then it makes em stronger. You should start with new batteries. WARNING never mess with a battery after or during charging .

if your batteries are cooked then charge them for a couple hours and do your errands and slowly you will have to replace one or two dead batteries every couple of months .
Most cart comps have a bat. tester . They can tell you the shape of each battery by testing . My Bats are 3 years old and I drive about 18 miles with four large people often .

Sorry for taking so long, I couldn't remember the name of the process. Desulfate your old batteries before installing the new ones and it will help keep the new one alive longer.

We used to do this with the big 8D and 4D batteries on the TMM boats to keep them alive longer.

Will these charge a battery that has gone totally flat?

see what you can learn here! Thanks everyone. My charger is locked up in a box. I have run the cart right into death. Each day it went a little less far and I know I need two replacements as Polo checked them for me and gave me the sad news. I'm asking all around.
