I replaced the battery in a DELL laptop last year. It was a J1KND from
Amazon. It cost £40 including postage.

High self discharge seems to be the fault in cheap aftermarket
batteries this means they go flat on their own in maybe a month or so
unusd and that leads to early failure. If you are using your laptop
every day its less obvious! Cheap cells used in manufacture is probably
the cause - what you can do to avoid this problem with cheapo batteries
- well there is a question! C+

NMIH and LiPo batteries tend to have a higher self discharge rate than
the earlier NiCads.
On top of that, built-in protective circuitry can add to the discharge
rate. Most of the current crop of laptops should be placed on a charger
every few weeks or so. Regardless of what a user does, the batteries
will loose capacity over time, such that they will need replacing
between two and four years after initial purchase/use.
I have an HP laptop that was purchased in late 2007, and due to the luck
of the draw, has had it's battery recalled several times. So, the next
time around, I'm finally going to have to pay for a new battery.
