Chosen Solution
The battery my laptop uses is an HSTNN-LB61, unfortunately its reached the end of its useful life. I searched for the model of the battery, and ordered a battery that was the same model, BUT what arrived was an HSTNN-UB6K . Now, the battery fits perfectly, its the same voltage, but with a slightly different capacity. I just have a slight concern: Is it safe to use this battery? Thank you for your support!
Capacity difference is fine. If it is a larger capacity it simply means it lasts longer on battery.
