The batteries on Kindle Keyboards are really great. I got a couple of these from eBay recently specifically because of the battery life (they have twice as large battery as later Kindles). Both were in barely used condition, for less than $20. The battery is excellent on both of them. Although I have not measured it, I would estimate it to be at least 10 hours. Probably even more. I read for 30 min on each of them daily, sometimes more, and charge them very rarely, don't even remember when the last time was - definitely more than 2 weeks ago.

I also bought a new sealed Kindle 5 non-touch and its battery is noticeably worse. It discharges more than KK3 when it is just in sleep mode and takes much longer to get back to full charge.

So, for KK3, I came to a conclusion that even though the battery itself is 6-7 years old, if the device has not been used much, it still works great. They key is to evaluate prior usage and stay away if it is unknown or can't be trusted.

Back in October, I bought a KK3 on eBay which was described as "New, open box". However, it had some minor wear on it and also the box was not its original box (different serial number). I returned it as incorrectly described at seller's expense per eBay policy. The seller was clearly lying, alternating between "I don't know anything about this unit, this is how I got it" to "This unit is in excellent condition, the best I have, - why are you unhappy". Since then, I was able to get two new KK3s for my family, one was sealed ($43, with 3G) and another new open box but truly unused ($26; Amazon still gives you full 1-year warranty when you register it for the 1st time). Everybody is happy with their device.
