No lithium... regular battery
400 hundred pounds
No need for that
Just slide off the battery cover from the rear of the scale and the battery easily pops out
It is the same as the width
I have no idea. The scale I have Ozeri Precision says it has to be used on a hard flat surface. I haven't thought of trying it on a carpet to see if it gives the same reading.
Would not calibrate. Wasted time and money. Do not buy this product.
Seems to work, not sure how accurate it is, maybe off by few ounces. No light, light up to the weight shown. It does not measure 5lbs by itself.
Yes, you can replace the battery in this item.
The weight of this item is 4.6 pounds.
