Category: Laptop Accessories and Parts Product Review: As a frequent user of laptops, I have come across various issues with my HP EliteBook Folio 9470M. One such issue was the battery life, which seemed to be dwindling faster than expected. After some research, I discovered that there were several replacement batteries available in the market. In this review, I will discuss my experience with three different types of replacement batteries for HP EliteBook Folio 9470M: a laptop battery, a notebook battery, and a bottom case hard drive cover. The first product I tried was a laptop battery from BT04XL. This battery is compatible with HP EliteBook Folio 9470 9470M Series HSTNN-IB3Z HSTNN-I10C BT04 BA06 687517-1C1 52Wh 14.8V -18 Months Warranty. The battery is easy to install and provides a longer battery life than the original one. However, it does not come with any warranty or guarantee of performance. The second product I tried was a notebook battery from Gomarty. This battery is compatible with HP EliteBook Folio 9470 9470m Ultrabook BT04 BA06 BA06XL H4Q47AA H4Q48AA HSTNN-DB3Z HSTNN-IB3Z HSTNN-I10C 687517-241 687945-001 687517-171 14.8V 52WH, and it provides a longer battery life than the original one. The battery is also easy to install and comes with a warranty of 1 year. The third product I tried was a bottom case hard drive cover from YEECHUN. This cover is compatible with HP EB Folio 9470M 9480M (2 Screws Included). The cover provides additional protection to the hard drive and makes it easier to access the ports on the laptop. However, it does not provide any battery life extension or warranty. In conclusion, if you are looking for a replacement battery for your HP EliteBook Folio 9470M, I would recommend trying either the notebook battery from Gomarty or the laptop battery from BT04XL. Both products are easy to install and provide longer battery life than the original one. If you are looking for additional protection for your hard drive, then the bottom case hard drive cover from YEECHUN is a good option.
