Questions about this item

How is the 45N1153 battery installed in a ThinkPad T440P, and which step is often missed?

Power off the laptop, slide the release latch, remove the old pack, insert the 9-cell unit until it clicks, then press the latch back; the step often missed is ensuring the latch fully re-engages.

What maintenance or replacement will the 57++ 9-cell battery need later?

The 45N1153 pack is a consumable; expect capacity to fade after several hundred charge cycles, at which point the entire battery must be replaced.
