Durst Carbon Pile Battery tester

[DeeJay]

I saw this at a second hand stall & bought it as I have a few 100amp AGM batteries to test. Looking thru Google there seems to be different instructions for different testers, none for Durst that I can find.
Does anybody know how to test a battery with this type of tester??

dont use it if they are deep cycle.

if they're crankers.

set the amps to the CCA or CA of the battery, plug it up and test hold the test for 10 seconds and it'll be showing the terminal voltage under load. if terminal voltage under load is over 10.5v the battery is ok.

double check the accuracy of the volts meter on it or piggy back a known accurate multi meter onto the batteries. If you have a clamp meter it can be useful to hook that on as well to make sure the amps you're pulling are whats on the dial.

wrong model... (pics were very slow to load)

try this.

hook up the battery

wind the knob clockwise until either A, the volts gauge drops below minimum or B, the amps gauge hits the CCA or CA of the battery hold it for 5-10 seconds and then back off, wait for 2 minutes and then test your next battery.

if A happens first the battery is not up to speed.

same caveats about double checking with meter and clamp meter.

Word 0f Warning
Battery`s can and have exploded when being load teated :cool:
I suggest a open area with a shower or water hose handy for that just incase moment;)

Thanks guys, I might have pushed the limit with my first effort, as I loaded the battery up to 1000cca !!
I would think that the Full River AGM batteries are dual purpose as the website does quote a CCA for the 105 amp, so it should be OK for testing purposes.
Good point about double checking the amps & voltages.

further to the word of warning....

dont hook the tester up with the load ramped up.
dont just ramp to full load, give it a couple of seconds at low draw to see what the battery will do, especially if its just come off of a charger
do clean the battery top and terminals first.
do cover the top of the battery with a heavy damp cloth.

if you have the hose and deluge shower setup its important you have an assistant with you whose not right next door to you when you do the test, if it all goes wrong you wont be the one in position to use the shower/hose

Winding it up beyond the batteries stated capacity doesn't do anyone any favours. If a battery is rated to 800CCA, wind it up to that and check the voltage - if it's above 10 ish you're ok. At 9.6 as the tester reads, you're borderline. Don't wind a deep cycle up on it, that's a really good way to massively shorten their life. I wouldn't ever put one near my full river batteries, they are too damn expensive.

I've been buying second hand ( 3 year) full river 105 amp batteries for $40.00 each, sometimes less off a guy who services standby factory fire fighting pumps, pretty lucky really... I have ended up with 18 good ones for a solar set up at home with 3 duds & another 4 that may be OK with desulphating- these are the ones I need to test. It was one of the duds that I cranked up, but only for a few seconds as the cables got hot..

wow. Fullriver. 3 years. $40.
:cool:

I may be naive but I was hoping for 7 in the van---

with a bit of abuse from the durst and some from a high current battery toasting charger couple in some clean water and some battery saver...

they'll come up.
