XTS5000 IMPRES troubles

[ConistonSafetyServices]

Hi all, I've got a problem child battery I was hoping to get some advice on potential recovery techniques. Allegedly it's a new or new old stock battery, from a reputable online vendor. Date code of 2235, Li-ion chemistry.

When placed into an impres charger, the battery will go orange and fully drain, then begin recharging. However, instead of the normal flashing then solid green of fully charged, it will instead turn orange and recon cycle again.

When inserted into a non-smart charger, light goes solid red like charging, then flashes red for a few seconds, then back to solid red.

What do y'all think, trash or saveable?

It's done. Get a new battery. Batteries age whether they're used regularly or sit in their original box on the shelf. An NOS battery is an old battery.

An IMPRES battery with a date code of 2235 is hardly old...barely even NOS. That date code translates to the 35th week of 2022, which was late August.

If the dealer is truly reputable, they will exchange the battery for you. You can also try contacting Motorola to put in a warranty claim on the battery, as it most certainly should still be fresh barely 3 months after its date code.

I would return that battery. it shouldn't be doing that with 2022 date code.

I must have had my glasses on when I read the original post. (I see better without them at reading distances.) I thought the battery was older. With a 2022 date code and it doesn't charge it, by rights it's due for a warranty replacement.

I've used the Arduino 1wire protocol library to read out battery data from the internal DS2433 EEPROM. I'm waiting for one of mine to come up bad so I can try to reprogram it with data from another good battery to see if it resets.

Is the battery Impress compatible? If so, what does the battery menu in the radio say? Regardless it does sound like you have a bad battery.

Is the DS2433 EEPROM inside a Impress battery?

Yes it's the largest chip at the bottom right.

Thats what's inside an Impres battery??

Yes an NNTN8092A.

 

[Opfor2]

Yes an NNTN8092A.

Wow, I wasn't aware that so much electronics went into an Impres battery

 

[mancow]

I think the DS2433 and maybe the temp sensor chip are what are causing so much of the battery availability shortage. DS2433s are out of stock everywhere and the few that are in stock are insane in price.

You're saying the batt on the impres charger it went thru a recondition cycle, started solid red charging normal, flashed green for 90% then went back into orange for recondition? Like a never ending reconditioning cycle?

Then on a non-impres charger it turns red, then flashes red, then goes solid for a few seconds, then back to solid?

Was this with the battery on the radio? Try taking the battery off the radio, and putting on the charger without radio attached. Weird but I have a batt that will not charge normally on a 3.9fw charger with radio attached, it will flash red but without on the radio charges normally. Its an expendable radio/batt I do not care about so thats how it works for that one

 

[chrismol1]

I'd love to put that batt on an impres battery data reader to see what its reporting. The impres batt data reader can correct a few errors on impres batts too as discussed in the impres data reader user guide. Sounds like the impres chip is whacked out. I recently had an newish impres batt a little whacked out that would not recondition, even tho 50 days had passed counted on the data reader without a recondition, had low battery alerts at 50% on the radio but showed 50% on the reader, obvious telling the radio something else. I had left it on the data reader and manually force it to recondition, it took around a dozen times of reinserting before it would force itself into orange/recondition mode. sometimes things get whacked out

 

[ElroyJetson]

I wonder how successful someone might be at bringing dead impres batteries back to life by a software reset? Of course that's not going to change the condition of the cells, but I'm pretty sure that the impres system will mark a battery as "Bad, do not charge or recondition" when its performance drops below a certain level, thus locking out a little bit of usability. Not much, I'd wager, if the system is working properly. But what about a battery that gets marked bad through some software glitch when the cells still have plenty of life in them?

Once I find another bad one I'll let you know.

It's an OEM Impres battery. And interestingly enough, it shows as fully charged with full expected information. Its' only detraction is that it cycles solid/flashing red, instead of going green. Quite peculiar really.

I have a few, if you're interested, PM me.
