Impres Battery

[MTS2000]

Hello all,

I received an extra Impres battery with an XTS5000 that I bought from a fellow board member earlier this year. He said the battery was just lying around not being used so he threw it into the box when he shipped the radio to me. However when I use it the radio will not Display a fuel gauge and won't display any battery info in the BATT menu option.

He recommended that I try and force a recondition to see if the battery would start displaying data but to no avail. Anyone know of a way to get the battery to start displaying data again?

Thanks

Put the battery in the charger. Take it out, and put it back in within 5 seconds. This needs to be done more than 30 minutes after the end of a rapid charge cycle.

[MTS2000]

And what will that do?

[escomm]

Force a recondition.......

[MTS2000]

Ok I did that. I will let you know how things go.

FYI, your Impres charger LED should turn solid ORANGE if you are successful in initiating the force recondition.
It may take several hours to complete.

[MTS2000]

Yes I followed escomm's instructions and the LED did turn solid orange. I did try this once before but I think I just forced the recondition state and not letting it go through the rapid charge cycle first.

So I will see what happens this time.

Thanks again

Well let it go through its paces on Saturday and still to no avail. The battery still won't display any infor on my two 5000's.

Any other suggestions?

Thanks

Has this radio ever shown batt info on any battery? What's the fw version? GARY

[MTS2000]

I have two XTS5000's and several other Impres batteries that read just fine with both of them. It is just this one particular battery that doesn't want to display info.

[MTS2000des]

It's very possible the IMPRES chip disabled itself if the battery was never initialized in an IMPRES charger to begin with.

This may explain why the battery that you received (that was "laying around" for an extended period) does not activate the battery gauge on the radio. It looks like it may be a non-recoverable situation.

Service bulletin FSB10166
February 2008
SUBJECT: IMPRES™ fuel gauge not shown after multiple calibration cycles in an IMPRES™ charger
MODELS AFFECTED: All Motorola IMPRES™ batteries
SYMPTOM: Radio display does not show the IMPRES™ fuel gauge after multiple calibration cycles in an IMPRES™ charger
CAUSE: After shipment from Motorola, batteries placed into long term storage that self-discharge below 2.4V, may cause the IMPRES™ fuel gauge functionality in the radio to become permanently disabled.

RECOMMENDATIONS:
1. Do not store batteries in containers with flammable materials.
2. Store batteries in well ventilated, temperature and humidity controlled locations. Optimum temperature is between 68°F (20°C) and 86°F (30°C). Optimum relative humidity is between 30% and 60%.
3. Battery must be discharged below 50% state of charge prior to storage.
a. New batteries are typically 30% to 50 % charged, when shipped from Motorola factories. Thus, there is no need to charge or discharge the batteries prior to storage.
b. Used batteries removed from service for extended periods (>30 days) should be discharged to about 50% of their capacity before storage.
4. Recommended charging intervals for batteries placed in storage:
a. Nickel Chemistries (NiCd, NiMH) every 6 months
b. Lithium Ion Chemistry every 12 months

Partial Recharging Process:
IMPRES™ Chargers
1. Insert, remove and reinsert battery within 5 seconds in IMPRES™ chargers. This will bypass the reconditioning cycle and enable the rapid charge mode (Steady Red LED).
2. Allow battery to charge for 30 minutes then remove and return to storage.

Motorola Non-IMPRES™ Chargers
3. Insert battery in charger pocket to enable rapid charge mode (Steady Red LED).
4. Allow battery to charge for 30 minutes then remove and return to storage.
