Guest leepatston Posted July 3, 2003 Share Posted July 3, 2003 what battery testing equipment do you use, we have just brought some ACT batt testers, they seem pretty good so far. Link to comment Share on other sites More sharing options...
Steve K Posted July 3, 2003 Share Posted July 3, 2003 I also use the ACT Intelligent Battery Tester. I purchased it at IFSEC this year on special offer at £100. I spoke to Yuasa about this tester, and they didn't rate it too highly. Probably because Yuasa are just completing research into the launch of there own battery tester(!). At the ACT stand, the importance of connectivity was demonstrated. You must ensure that bith croc clips make good contact with the battery terminals, otherwise false readings are obtained. I am very pleased with mine. It does give me confidence, rather than the old way of connecting a multimeter and turning off the power and watching the voltage drop over a period of ten minutes! Hope this helps!

dinefwr Posted July 3, 2003 Share Posted July 3, 2003 I also use the Act meter one Link to comment Share on other sites More sharing options...
Service Engineer Posted July 3, 2003 Share Posted July 3, 2003 I use a modified ACT meter one, it was one of those with a cigarette lighter on that drew 6 amps from the battery. I`ve changed the load to a series of 20 watt resistors that draw 3 Amps at 12 volts. I have my meter connected to monitor the voltage drop, during a few minutes test period. ........................................................

Guest Adrian Posted July 3, 2003 Share Posted July 3, 2003 B) I also use the ACT IBT got mine at ifsec as well, It is far better than that cigy lighter thing I used to use. Adrian B) Link to comment Share on other sites More sharing options...
Guest leepatston Posted July 4, 2003 Share Posted July 4, 2003 Do you find that with the ACT ones you change alot of batterys, we have only had them a few days and it said we should change more than half of the batterys we have tested! Link to comment Share on other sites More sharing options...
Service Engineer Posted July 4, 2003 Share Posted July 4, 2003 I always have my meter across the battery terminals when drop testing the battery. If it drops down to 11.4 volts then I advise the customer the battery may need changing at the next service. If at any point during the test the voltage drops below 11.0 volts then I advise the customer that the battery needs replacing. I use a CALIBRATED test meter and my drop test is a 4 Ohm load for 3 minutes. At 12 volts this would draw 3 amps current. ........................................................

Guest swampdog Posted July 12, 2003 Share Posted July 12, 2003 The only problem I have with the ACT battery tester is that after 8 mo. of use, it seems to need recalibrating. I've sent it to the mfg. for this. You'd think for a tool that cost so much, it would last longer. However, it is very handy to show the cust. in an layman kinda way that your not trying to sell them equipment that they dont need. Link to comment Share on other sites More sharing options...
An Engineer Posted August 22, 2003 Share Posted August 22, 2003 Did not know Yuasa were developing a tester. I hope its better than the ACT unit as in my opinion its not very "intelligent" . It's not just my opinion but also that of many colleagues. Some also say it draws too much current on the battery. Also, well over priced, thank god we get issued them by company.

Steve K Posted August 22, 2003 Share Posted August 22, 2003 Dave, what do you use for your 4 ohm load? Surely a 4 ohm resistor would burn out?
