The term Hybrid Battery is confusing here. This is a standard 12V battery used to power up the computers of a hybrid car.
I had a Toyota Prius whose main hybrid battery had to be changed. It was a huge size, multi cell (probably 28) and about 200V.
Later it's 12V battery died which was originally a YUASA 12V 35AH (probably). I changed it a Hankook sealed battery, working good so far since past 3 months. I think you had got some old stock of Hankook. When I bought this Hankook, I took the Load Tester from the same battery shop, tested 03 batteries on load and believe me, two of those were showing bad.
Provided you get a fresh battery, a Hankook should be way better than any local battery.
After changing the 12V battery, my CD player stopped working and asking for some SD card .I had to get it fixed from a audio shop for Rs. 500
