Sorry it took so long to get back to you. Both units came with rechargeable batteries. I did charge them up over night, then let them discharge completely, and did this a couple of times. We do have a fair amount of chatter on the radios as the day goes by, and sending of call tones about the time we think the rabbit is getting close to one of us....(very rude horse play) but I've not had one go dead in a day yet. My next purchase is going to be a head set so I can use the vox, and hopefully kill a few rabbits!
The FRS channels use low power, and the batteries last much longer on low power. Most of my hunting is with in shot gun range of each other and low does just fine. Here in the rolling hills of Tennessee, about 3/4 mile is about normal, reliable distance. The frequency these radio's talk on are pretty much line of sight, and the higher powered radios boast of 5 to seven mile range would be under perfect conditions, or hill top to hill top. I'm not sure the extra power would buy you anything, but would certainly hurt your battery life, as everything comes with a price.
My buddy has a set of the Midlands, also with rechargeables. I'm thinking, but not sure, that the Midlands have more batteries in them, meaning more weight. Weight might not seem like an issue, and it isn't early in the morning.....but about 3 in the afternoon, after chasing the hounds all day, I usually wish I'd have brought the .410 instead of the .20 gauge.
Of the 2 pair I have, I'd have to say I like the Motorola's best. The Unidens have some features that the Motorola's I have don't, like NOAA weather radio built in. The Unidens also scan all channels which is nice as this will often clue us in to other hunters in the area.
However, the Unidens volume adjustment is push button, up down arrow, and the Motorola's is the old turn the knob style which is much faster when the "buddys" give you the call tone right before the rabbit arrives. Also, the Motorola's are a bit clearer and easier to hear, expecially in the high powered GMRS channels at close range. The Unidens are a bit over modulated in this close range senario, but are fine on FRS even at close range.
I wish I could tell you more about the Midland product. Midland is an old respected name in radio's, and is why my buddy made his choise for the Midlands. We haven't be out togather with his Midlands yet so I can't tell you how they sound or what features they have.
I will say, that after the first trip with the radio's, just about all my hunting buddies have bought a set and now bring there own when we hunt togather.
