Re: Review - Digitech AR-1780 Multi-band Radio Receiver - battery choice

I will just describe my experience with the 18650 batteries in these units. Both radios were purchased from the Israeli reseller who, for a while, was the only source of these radios for United States buyers.
Stock "XHDATA" branded battery, 2000 mAh. One can't hold a charge at all; the other is the best-behaved of all the batteries I've tried. Still, it needs recharging about every 3 weeks even if it isn't otherwise used.
"UltraFire" (an unfortunate name considering the history of lithium-ion batteries), 2600 mAh. Could not hold a charge as long as the XHDATA-branded battery. I am using an UltraFire battery in one of my XHDATA radios. It needs a charge about every week and a half, even if not used.
"Internova", 2000 mAh. Worst performer, on average: holds a charge for about a week.
Those latter two brands were purchased from Amazon.
I have other radios that use the BL-5C battery (Radiwow R-108, Tivdio V-115). They can hold a charge for months.
I also just purchased a Tecsun ICR-110, with a Tecsun-branded 2000 mAh 18650 battery. So far, so good, but I've only had it for a few days.
As for the battery indicator on the XHDATA model: it may be inaccurate, but it doesn't matter for the on/off switch: once it's flat, it's flat. Fortunately, the XHDATA stores station memories in non-volatile data. The inconvenience in this case is having to turn the beep off again once the radio is revived, and having to reset the clock. But I'm finding it tiresome to keep watching this. That's too bad, for there are many good things to say about this model.
I have two Digitech AR-1780s and their battery indicators seem to be just fine, for 4 AA alkaline cells - always the Eveready brand; I've had issues with Duracells being leaky.
