R30 R30 Battery

[palmerjrusa]

Using my Powerex MH-C9000PRO professional Charger-Analyzer (the best charger on the market) I determined the capacity of ACDelco AAs.
For ACDelco AAs at a discharge rate of 100 mA = 2146 mAh.

The available "capacity" of alkalines very much depends on the discharge rate due to alkalines having a high internal resistance (NiCads and NiMHs have a low internal resistance and are not subject to this phenomenon = high discharge rates do not significantly affect the cells' nominal capacity).

Still running tests here.

I think using Powerex 2700 mAh AAs and the right IC-R30 settings an operational time of 10 hours or more is possible.

FYI regarding ordering the ICOM IC-BP287. I ordered this on 02-16 (6 days ago) and have only received an order acknowledgement. No shipping date, no tracking information. This item was shown in-stock and still is showing in-stock. I sent another message this morning requesting that information have not received any response.

Where did you order it from?

Where did you order it from?

And how much?

 

[palmerjrusa]

As above with GPS off.

ACDelco AAs = 6 hours, 30 mins operational time

Currently doing the same with the Amazon High Capacity (2400 mAh) AAs

As original settings with GPS = off

Amazon Basic Brand High Capacity (2400 mAh) NiMH AAs.
Operational time = 10 hours, 4 mins

Wow, thats some good batteries. Got a link to those batteries?

Currently doing a test run with Maha Powerex 2700 mAh NiMHs so they should have an even longer operational run time.

The Maha Powerex 2700 mAh (the most the technology is capable of) AAs are the highest capacity AAs available, are accurately rated and made in Japan.
Maha manufacture Eneloop cells in Japan = the gold standard for NiMH batteries.

Ignore all the other brands that claim the above capacity or even higher, they're not, those Chinese brands routinely inflate the capacity of their cells. I know this, done the testing.

It's important to have a good charger.

This is easily the best charger on the market:

Just tried my AA case holder for the 1st time. Over voltage with duracell batteries. Had a issue a year ago when I had my R30 plugged into a usb port on my computer. Got the same warning. Since then, been unable to put the R30 in the cradle to charge. Have to remove the battery and put just the battery in the cradle to charge. Been holding off sending it in to Icom. Guess its time.

You tried a complete reset?

Think I did back when this happened but will try again just to be sure . Thanks.

Just tried it. Nope. Still get the warning, then shuts itself off.

Which repair facility to get your fixed at? Am considering the one in michigan.

You get the same warning with NiMHs in the battery case?

Don't get the warning with the battery that came with the R30. But, I can only charge it when its in the cradle by itself.

It might be worth calling Icom and talking with one of their technicians, they might have encountered this issue before.

Just wish I could hook up an external usb battery like I can with my 436. Can get over 24 hours scanning on my 436 with the external battery.

Do you mean using a USB power bank such as those to boost a cellphone battery? I use these all the time with my R30 (and 436, TRX1 etc) with power to the micro usb port.

Just got off the phone with Icom. Need to send it in. Will send it to Michigan since its closer. Told me I can send it to them in washington if I want to. Ever deal with the folks in michigan?
