Foxwell BT705 FAQs:

Q1:If i had a battery that was in good condition, but simply needed a charge, what would the unit tell me? Would it say good or bad?
A1:Yes, it will tell you if the battery just needs a re-charge , or it needs to be replaced. This unit is very simple to operate. It tests also the charging system of the car.

Q2:Can you test 12 volt deep cycle batteries?
A2:I use it on everything up to 8D AGM.

Q3:Does the bt705 test 6 volt batteries? the instruction manual online says "developed to test 6v & 12v batteries", description here says it does not?
A3:Sorry,FOXWELL BT705 can not test 6V batteries

Q4:Dose it support a spiralcell agm battery?
A4:BT705 battery tester will test a spiral cell agm battery.

Q5:What is the minimum amount of voltage to make tester work?
A5:I don't know exactly but it should be much lower than 9 voltages because the ignition for a car needs at least 12 voltages, so... If you battery is dead... This tester is gonna tell you that your battery needs to be replaced, recharge or good battery...
