Nice work. A small switch between the cathode of the Schottky diode and second positive lead of the battery would allow switching between standard and rechargeable batteries. Then you're not having to do any resoldering to change it later. Just a thought for anyone thinking of doing this mod to their own radio.

Awesome work & extremely useful for those of us who own similar radios ie IC-7300, IC-9700 etc & so many other radios & devices which use similar setups knowing we can use CR2025/32 (Non-rechargeable) & ML2032 (Rechargeable). Of course, would need circuit mods for an ML2032 to adjust charging current. Thanks so much for sharing, Peter & God bless!

Hello Peter this seems to be an iCOM Disease. The IC-7300 does act up with the same Symptoms. I decided to replace the Battery inside my IC-7300 with just a simple Battery Clip soldered to the Mainboard to use regular 3V-DC CR-2032 Lithium Batteries "non rechargeable" because we know how long it would take to leave the Transceiver switched on til the rechargeable Battery ifs just 50% charged up.

@PPGATL Жыл бұрын
Peter, I would recommend you take a look at the BR2032 battery too. The medical device I work with contains a CPU board which came with the BR version. These batteries technically have less than half the capacity of a CR 2032 but the actual current drain of the RTC on the board is so tiny that I couldn't measure it with a standard Fluke 79. It turns out that batteries in these applications discharge not because of actual current draw, but because of shelf life expiry and thermal cycling in the equipment. The BR version holds a usable charge in these conditions much longer. So despite the lower mAh capacity, the BR lasts much longer than a CR. The BR is also not rechargeable so if I was going to replace the battery in my 7300 (and I think it needs it) I'd probably put something bigger but rechargeable, or I'd use a BR instead of a CR.

I've found that some devices start to get flaky when a 3V coin cell drops to 3V and below so a fresh battery would be in order for sure here...the clock circuit may not be so sensitive. I have the same issue with our 7300 and 9700 and am really disappointed in Icom for having changed their designs to use the smaller capacity batteries as it could have been so easy to do as they'd done previously in other radios. It would be very interesting to see how the rechargeable version would work. TNX for sharing Peter, another great job! 73 - Dino KLØS
@TRXLab Жыл бұрын
Hi Dino, The internal INTERFACE REAL TIME CLOCK MODULE RX - 8801 SA / JE works down to 1,6V. That's mean the coin cell can drop a bit... Maxell specified charger for ML2032 uses 2-3mA charging current for charging the battery in approx 24h. So you need to adjust the resistor slightly down for a bit more current. Many uses the ML3032 even without a charging current modification. But a bit more current would definitely help. Thanks for comment 73

Interesting that you mentioned commercial users, like the marine radios. Icom's marine HF radios actually have a battery holder for the battery for the GPS state, so it's easily replaceable. Both my IC-7300 and IC-9700 have dead batteries, and I used the ML2032 cells in them.
@Aleziss Жыл бұрын
did you change anything in the charge capacity of both your radios ? it will take a really long time to recharge a ML2032 with the current charge of a 1mA battery cell !
@AndrejaKostic Жыл бұрын
@@Aleziss Well, in IC-7300 charger, there's a 3V3 voltage line, with a L1SS400T1G diode in series, which should have around 0.6 V forward voltage drop at around 1 mA of current, and should prevent battery current from going back into the 3V3 line. Then, there's a 3k3 resistor in series with the battery, limiting the charging current. My calculations tell me that the expected charging current is around 0.8 mA, giving us some two weeks to charge the battery fully. Now in my case, the power supply is left on for say 6-12 hours a day, pretty much every day, so this isn't as big of an issue (but the radios still managed to kill the original batteries, immediately after warranties expired), however, for faster charging, the current limiting resistor would need to have its value reduced. On the other hand, many ML2032 manufacturers recommend maximum charging currents of 2 mA, which is still a charging time of a week, so I didn't consider the change to be significant enough to go try replacing the resistor. Now, this leaves the users who want to quickly charge the battery, and let the RTC run for long storage periods without a good solution. Perhaps a super-capacitor could be a better fit here? I didn't do any research in that direction.

FLRig software, for the 7300, has the capability of automatically setting the rigs time via CAT every time the program starts. The function can be also be triggered manually. Of course this requires a computer connected and the correct time on the computer, which I achieve by using a Raspberry Pi with GPS module attached. Unfortunately this function isn't available for the 9700, at least on the version I'm currently using. I don't know if it works with the 7610.

It would extend the time using a CR2032, but once it is dead it is dead. The 1mAh battery didn't have a lot of capacity, but 200 recharges would be equivalent to 1 CR2032. The other option here could be a rechargeable CR2032, which are not expensive, and therefore no modifications would be needed other than installing the 2032 rechargeable in place of the original battery.
