How easy is it to use 18650 cells as replacements? Can you solder to them
easily without damage, or whatever?

I just wanted to salvage the OK cells in an expired netbook battery pack
as there is usually one cell letting the pack down. Getting the pack
container open proved impossible without wrecking it beyond re-use.

Soldering the cells is possible if you have a powerful soldering iron so
that you don't heat the cells for too long.

Frankly, it's not worth the effort.

You wouldn't think its such a palaver buying a decent laptop battery!.

So we did a further look around and 2-power parts came up website
registered to psaparts in London seems a large ish UK based supplier.

Seems that 2-power aren't that bad according a couple of reviews so in
the end did a search for the larger capacity battery several suppliers
came up from around 75 to 54 inc vat so went to this lot;

thelaptoppowersupplyshop.co.uk

Registered to a cottage in Welsh Wales so we'll see what becomes on that
then!.

It really isn't possible to cut the battery case open and now I've got
me magnifying glass from ye shed it seems the original battery, its a HP
6930P, was dated 3/2010 so way past its use by date!. Nice chunky
machine goes very well with a solid state hard drive used out in the
field quite a bit.

So we'll see how we get on with this one then.

Thanks to all who helped


So said battery has turned up via DHL from an address in London i think
its where 2-power are based. Well packed lots of info sheets and safety
information and charging and use info. Has a few stickers quoting the
original HP/Compaq part number on the battery and box.

Decided to get the 9 cell higher capacity version which did exist its
just that HP don't make them or the 6 cell anymore. It does look very
original and on the box says celled with Samsung batteries. Anyway has
charged up and we'll see if it does do the claimed discharge times and
as to longevity we'll see about that in a whiles time but all good thus
far!.
