Direct replacement
Did the trick. A bit of a project to disassemble the keyboard to replace this battery, but well worth it. Good as new. A few good You Tube videos to help with the process.

Short Battery Life
I bought my K-800 keyboard about 10 years ago, the stock battery at that time would last 7 or more days without being recharged. now it would only last maybe a day or less, so when I purchased this new battery, I expected that it would last 7 or more days, but unfortunately not, the brand-new battery might last 3 days that's it. Update: 061526 now the battery dies the same day after a full charge, just junk.

Don't buy for the price like I did
Neither battery seems to want to take a full charge even though they are getting charged over night and if I unplug the charger they only last a short time. Not near what the original batteries were that came with these keyboards. The original batteries would take a full charge in a few hours and would last for a couple weeks before needing another charge. They lasted a full three years before needing replacements. These batteries do match the original in every way and look identical but think they were just old when they were sold to me. Chinese knockoffs.

Fully charged battery only last about a day.
The replaced battery only last about a day after over night fully charge. Got the same result two days in a row. Overnight charge it to full -> start using it in the morning -> by the end of the day, the LED shows red. Going to return, since my old removed battery still last about 3 days of the same usage.

Terrible quality. The original "dead" battery works much better that this brand new battery!!!
I purchased this battery to replace my loving keyboard. The original was functioning well more than 6 years and was not holding charges recently, So I decided to get this replacement battery and this does not retain charge for only 2-3 days. compared to the original which I was charging it every 2-3 MONTHS. So basically it's working as if the battery was never replaces.

Lasted one day
If I could give this zero stars I would. It lasted one day.

Didn't Last Long
Six months later and it does not hold a charge. I have to get a new battery (from someone else).

Muy mala
Compré la batería por qué ya descargaba rápido la que tenía el teclado, y quedó igual, está batería no retiene nada de carga
