ZTS Help??

[dano101]

I was looking to order a ZTS pulse load tester (MBT-1) and was curious if the unit had any problems reading 17500's. The 3.6V section on the tester lists a variety of 3.6V except 17500's.

Also, any clue where to order one cheap? I live in Canada so it will have to cross the border.

I'm looking to buy one of the ZTS mini MBTs.

Thomas Distributing has them and is one of the regularly mentioned sites on here.

Battery Junction is another one.

The key is to avoid using UPS as the shipping company....UPS' brokerage fees are insane.

My main concern though was wether the MBT-1 would read 17500's accurately as it is not listed on the tester.

I was wondering this too. Where does it say 3.6v? Looking at the picture of the MBT-1 on The link above, I do not see anywhere that says 3.6v. I see 3v lithium coin cells & other 3v lithiums but nothing for 3.6v Li-Ions. Am I missing something here?

A DMM is much more useful for Li-Ion cells. Unlike most other chemistries, the resting voltage of a Li-Ion cell is an accurate indication of its state of charge, and the maximum charge it can hold is a good indicator of its condition.

Um, don't you mean "Voltage" DM?

Same thing. Voltage directly correlates to state of charge in Li-Ions.

OK, I'm with you. I guess it's just how you worded it. The condition of a Li-Ion cell can be determined by the drop in voltage after it has been charged. If you have a good charger, the cell will finish @ 4.20 Volts. If say after a days time the cell still reads 4.20 Volts, it's in excellent condition. If it reads 4.18 Volts, it's very good. 4.10 Volts is fair and 4.00 Volts is considered end of life.

My point is I look at it as the maximum Voltage the cell holds after charging. We are both saying the same thing, just in a different way I guess.

Yes, we are both effectively saying the same thing. The key word in this, which we are both using, is 'hold'.

I agree with your figures too - when a Li-Ion can only hold 80% (4.00V) it is time to retire it.
