HP682 Battery Drain when off

[rmetcalf]

Hytera HP682 Battery Drain when Powered Off:

Both Radios:
Model # HP682-00000000-M000DC-Um-0-D
Firmware A2.5.09.015

I have two HP682s but only one of them drains the battery when it's powered off.

I have the same code plug in both radios. Battery Save is set to 1-4 and 5 seconds. I have looked through the codeplug and I did notice under Conventional > Gen Settings > Accessories, that GPIO Pins was active for "ACC TK" and Debounce was checked. I changed that to None. Then on Friday, I left the one radio powered off for about 6 hours with a fully charged battery. After that 6 hours I turned the radio back on and its down to 1 battery bar. The other HP682 works just fine and doesn't drain it's battery.

Anyone have any idea what the problem is?
Thanks in advanced

Swap batteries to see if problem follows. When batteries age out self discharging is not uncommon.

Measure and compare resistance at radio battery terminals when switched off. be aware most VOM meters have positive on the black lead when in ohms scale. so check yours and if that is the case, black lead on + terminals and red on - terminal.

Brand new battery was purchased and used. Same results

I don't know what any of that means.

He means measure resistance between the plus and minus pins on the back of the radio with battery removed. Open or infinite resistance means no drain while some resistance would mean drain. Most radios have some drain because the off position does not physically break the circuit. When I turn my PD982 off it makes shutdown sounds after knob is clicked off which requires power.

Again, I don't know what any of that means. I guess I'll need to take it to someone to have it tested.

Apologies i cant elaborate more and it may not be your specific problem but talking to my local Hytera dealer the other day they also mentioned a variety of issues with the new H series suscribers and specifically a sporadic battery issue with the HP682. They had been in regualr discussion with the factory as a long time dealer and experiencing a reluctance to admit a problem or commit to a fix. The other issues were hardware quality related versus the orginal MD/PD generation. We were bouncing all over the place in the discussion and as i have old generation hardware didnt think to ask further about it. Please do let us know if you identify a specific issue or fix.
