How long do you have to hand crank to charge it

Quit cranking, let the sunlight charge your radio. A few hours and when you see 4 bars you are good to go.

Does the replaceable 18650 battery have tabs? Is there any reason it could not be replaced with a 3400 mAh 18650?

I bought the "first-generation" of the ER310 radio in March 2018; from this same page on Amazon. The battery died recently. The battery for my radio has a "pigtail" connector on the end, not a standard battery connector. The battery has been discontinued. The Midland website gives a phone number to call if you need the pigtail battery. When I called they said the battery was discontinued, and they would sell me a newer model of the radio, that doesn't require the discontinued battery, for the price of the old battery, which was $25. So I just ordered that. There's now a second-generation version of the ER-310 radio that doesn't use the "pigtail" battery. I can't tell from the photos on the Amazon page if the radio sold on this page is the "first-generation" or "second-generation" one. I would think it's probably the second generation; if it's the first-generation, I wouldn't buy it.

If i just want to keep this radio for power outages, what is the best way to store it? battery fully charged? disconnected? plugged in all the time?

Hello There, for this purpose we would suggest getting the battery up to a full charge and then disconnecting. If left connected, the battery will be running to power the clock and WX features. Be sure to pull it out every 3 months to plug the battery in and make sure things are still working properly for those emergency situations!

Can you program alerts for what counties you neef?

Hello Brandi, the ER210 does is not programmed for S.A.M.E codes. It has 7 NOAA/NWS weather channels to choose from. • Press the BAND button to select the weather band. • Then use the TUNE buttons to select the strongest weather channel in your area. Typical broadcasts are within reception distance of 25-50 miles of the weather station. Fully extend the telescopic antenna and rotate until reception is clear. The ER210 can receive broadcasts up to 50 miles from the weather station depending on your location and conditions of weather, terrain, etc. If reception is not good, try a different location to find a spot of improved reception. If indoors, placement near a window usually improves reception. If a weather broadcast cannot be heard on any of the 7 channels, contact your local NOAA/NWS office and verify the closest station is on air. Their web site is http://www.nws.noaa.gov/nwr/
