Frequently Asked Questions

What is the difference between runtime with and without pre-buffering? Pre-buffering keeps the camera in a constant state of temporary recording. Using this feature reduces runtime to approximately 6 hours, while standard standby/voice use lasts up to 18 hours.

Can I charge this battery in an older IMPRES 1 charger? While some older chargers may physically fit, we highly recommend using an IMPRES 2 charger (like the NNTN8860) to take full advantage of the advanced diagnostic and fast-charging features of this battery.

Is this battery intrinsically safe? No. The Motorola PMNN4549A does not carry a TIA or UL intrinsic safety rating. It should not be used in environments where explosive gases or dust are present.

Warranty

1-year manufacturer's warranty.

Cool, Fluffy, and Excellent Value
Color: White, Size: Queen (Pack of 2)
I recently got the Utopia Bedding Queen Size Bed Pillows (set of 2), and they’ve quickly become my favorite pillows for a good night’s sleep. Right out of the package, they fluffed up nicely and feel soft yet supportive. The down alternative filling gives a plush, comfortable feel without being too firm or too flat, and the gusseted design adds extra support for back, stomach, or side sleeping. I’ve tried them in all positions, and they hold up well without collapsing overnight. Another big plus is that they stay cool while I sleep. Even during warmer nights, I don’t feel overheated, which makes a huge difference in comfort. The pillow covers are smooth and feel like hotel-quality fabric, giving the bed a clean, luxurious look. The only minor thing is that they may take a little time to reach full fluffiness after the first wash, but that’s normal for down alternative pillows. Overall, these are soft, supportive, and high-quality pillows at a great price. They’ve improved my sleep noticeably, and I’d definitely recommend them for anyone looking for a comfortable, versatile pillow set

Well priced luxury feel.
Color: White, Size: Queen (Pack of 2)
This set of 2 pillows is very luxurious and comfortable to sleep on with good height but not so much as to elevate or lower the head to an uncomfortable degree. I just received them so they need time to air and expand fully but right out of the compacted box they are full and very comfortable. The fabric is very soft and there is no odor. These pillows are definitely a good price for such a luxury item. I think I will enjoy them for some time to come.

Soft...but fluffy and tall
Color: White, Size: Standard (Pack of 2)
I've only had these pillows for about a week. They are a great quality pillow. The cover is soft and seems well made. My only complaint is that they are VERY full pillows. If you're tall with broader shoulders, you'll probably love them. If you're shorter with a smaller frame you will probably feel like your head is too high and your neck at a weird angle (my problem). There seemed to be mixed reviews about softness....I would consider these a nice medium pillow. Soft filling but firm enough that your head doesn't sink to the bed. Definitely NOT a down-like pillow, so if that's what you're looking for, this is not for you.

Soft, fluffy and surprisingly comfortable
Color: White, Size: Queen (Pack of 2), Color: White, Size: Queen (Pack of 2)
I really liked these pillows. I tried to show different things in my photos because I wanted people to see the details: the design, how fluffy they are, and how full and thick they actually look. They are so full that the pillowcase even looks tight once you put it on, which I actually loved because they look luxurious and well-filled. At first glance they look very thick and high, but once you lay down they feel soft and fluffy instead of hard. They adjust comfortably and feel very cozy whether you’re sleeping, relaxing, or even reading before bed. I think they offer a really good balance because they feel supportive without being stiff. Of course, pillow preference is very personal—some people like lower pillows and others like higher ones—but for someone who likes fuller pillows that are still soft and comfortable, these are great. They are spacious, cozy, and feel like a very good purchase overall. I honestly don’t have any complaints so far. Definitely happy with them.
