This is a 6-cell battery.
This battery can be used in these models:
- Inspiron 1525
- Inspiron 1526
- Inspiron 1545
- Inspiron PP29L
- Inspiron PP41L
Although the numbers didn't match the battery fit perfectly and works great
Good start-up - initial life comperable to when the original was new. I typically use the laptop plugged in - we'll see if it lasts the four years that the original did.
