APX APX 900 battery display issue

[dmason04]

I have an APX 900 that has an IMPRES battery in the unit. It doesn't show the capacity in the top right. I've read that the solution is to recondition, however, when I put it into the IMPRES charger, pull it out and replace it quickly, the battery refuses to condition. Is there a solution to this?

check your battery model number.if it isn't a Motorola made battery it may be a non impress model. also check your charge model number and firmware version. the older the charger firmware version this becomes a problem as the chip in the battery also has firmware in it that interacts with the changer. this fact is not known by most of the radio shop techs. you may have to have it sent to Motorola to updated.

Also check to see that the middle battery contact isn't mangled. The wonderful design of these radios sometimes leads to this pin being damaged and this pin is what carries the IMPRES data (one wire serial data) to the radio.

Turns out this battery isn't IMPRES, it's identical to the IMPRES version, I didn't realize that M made a regular version of that battery until now.

all the motorola branded batteries in the apx900,4000, and xpr series are impres. Sounds like you got an ebay/amazon special.

Negative. In my hand is a Motorola PMNN4406BR Li-ion 1650 mAh XPR battery, & it’s not Impres. Fits the 7550, & other radios that share that platform.

I stand corrected.
