Clam shell for XTS5000/3000 Motorola and energizer lithuim batteries Will not work

[rbluesky]

Hello I have a BRAND NEW orange and black XTS clam shell to use 12 AA batteries OK no problems using AA alkaline batteries, But i bought a set of
Everready Lithium NON-rechargeable batteries MY radio WILL NOT TURN ON !! YES YES I checked the polarity 3 times ! the same will both radios the xts3000 will not turn on either I just wanted the extra time the lithium.s would provide THATS not going to work !
What is wrong with this clam shell ??? AND can I use rechargeable batteries in the clam shell ????

Any info would be great!
Thanks

Is it bought brand new ? or Brand New Old Stock ??

I seem to recall that the early Clamshells had a recall due to some bad connection issues (READ FIRE HAZARD) that is/was over 10+ yrs ago

Too much voltage! Lithiums are higher voltage. When putting 12 together the small difference becomes toooo much.

Hi Frank that's what I thought, Once I put alkaline in it works FINE Frank can I USE rechargeable batterys either Ni-cad o rNi-mah??

uhhhh no... I believe the OP meant energizer and not everready. Anyways the Lithium AAs are 1.5 volts, the same as voltage as your standard alkline battery. I think you might be confusing it with a Lithium 14500 battery which is the same size as a AA.

PLEASE READ my post again < hello !

I had and just also re-read and comprehend HELLO to you
You still have not answered my question, since NEW to you may not be what many of us would consider NEW

Brand New , New Old Stock, bought use and new to me

The clamshell likely uses a series parallel arrangement of 2 times 6 AA batteries in series.

I happened to have a pair of new old stock energizer Lithium/Iron Disulfide (Li/FeS 2) primary batteries I bought at a garage sale a decade ago. I measured the Open Circuit Voltage of them at 1.867 volts each. I also grabbed some generic Publix Brand AA Alkaline batteries and measured them at 1.607V (also OCV). So if you have 6 of those in series. The Alkalines will potentially deliver 9.642 V open circuit volts and the Lithium batteries will deliver 11.202 volts. I suggest this voltage is excessive for the radios.

A "good" Lithium/Iron Disulfide battery will deliver >1.74 volts. 5 of those will deliver >/=8.7 volts to end of life at </=8.5 volts and ~9.335 V when fresh. I suggest removing one battery from the odd number string and one battery from the even number string and replace each with a jumper or a dummy battery that creates a short from each end of the cell location. Please review the manual for the clamshell to determine if my suggestion will yield the correct results.

You want each series string of 5 batteries to measure 8.7 to 9.335 volts. Install the batteries one string at a time and test the terminal voltage after installing the jumper for each string.

RFI beat me to the fact that the clamshell may be 2p 6s proving approx 9Vdc. Yes a dummy in each string of 6 should get you going.

62 trucker, have run into the AA lithiums before. While they will work fine in most things as a straight 1 for 1 swap, when used in a 6 string, the higher voltage they produce can cause voltage sensitive devices to not be happy. And they may be 1.5v when about dead, they start life out much higher as RFI indicated, and hang there for most of their life.
