I took them out just as a prophylactic measure. I *think* I know that Ni-Cd cells don’t burst/leak over time but I would rather not perform that experiment with a KX3. My Bioenno battery is a small price (in $ and peace of mind) to ensure that I don’t destroy my radio. :) 72, Rich Hurd /

I stopped keeping batteries (NiMH) in the internal tray when the rig got stuck in an error state while trying to update the firmware. The fix for the issue was to remove all power to the radio for a short time, maybe half a minute, then restore power and update the firmware again. Trouble is, if

Scott, The KX2 will not produce its full 12 watt output with the internal battery pack - expect a maximum of 10 watts, but if battery life is a consideration, use 5 watts output. You can always use an external power supply or battery pack of up to 15 volts to provide full 12 watts output.

I don't own a KX3, but it appears the internal batteries are a limitation. By contrast, the KX2, which I do own, uses an 11 V internal Li-Ion (Li-FePO, I believe) battery, and is designed to provide full output at that voltage. (The KX3 requires at least 12 V.) One possibility for the KX3

I found that the standard Eneloops were better for my KX3 than the Eneloop Pro. While the Eneloop Pro has a higher total capacity at lower rates of discharge than the standard Eneloop, my samples had a higher internal resistance than the standard Eneloop. That translated into a greater voltage sag

I've had good results in a number of applications with any of the "pre-charged" NiMH. "pre-charged" is the key. That's the normal marketing-speak for low-self-discharge. Eneloops are a very safe bet. 73 -- Lynn On 5/9/2018 8:01 AM, Walter Underwood wrote: No, the Amazon Basics batteries

How do they test for actual capacity? The first Q on Amazon says these 2800 mAh batteries actually tested as 2000 mAh. That is believable, since they are about half the cost of the Amazon Basics batteries. Amazon Q: https://www.amazon.com/ask/questions/Tx1YAAW3L67OV3R/ wunder K6WRU Walter

No, the Amazon Basics batteries are not the same as the Eneloop Pro. For one thing, they are 2400 mAh instead of 2550 mAh. The best bet is that Amazon Basics batteries are the previous version of Eneloops, made in the old factory. But that is a guess. Personally, I’m not interested in saving

The KXBC3 checks battery voltage before starting a charge, and if it's not within a reasonable range (6.4V to 11.2V) it will indicate an error condition. Battery manufacturers recommend not discharging cells below 0.9V, and healthy cells will normally hold a residual charge pretty well
