These are great BUT bloody expensive 

Anybody know of a decent non oem one that's reasonable ?

Bump

Don't be a pikey, buy proper ones - not Chinese knock-offs that (can) amount to unexploded ordnance 

On a more serious note, I've seen a few folks do tear-downs of non OEM battery packs - it seems to be pot luck, with some being good-brand (Samsung, say) 18650 cells and others being clearly "recycled" no-name lower capacity cells, all masquerading as the same thing..

Assuming you may have some dud ones, Crack them apart and replace the Cells.

Gotcha

Not really 

When I poly'd the back end on the omega last year, I bought a Ryobi impact gun from the one+ range which twists 400Nm of torque. This turned out to be a great bit of kit.

My jigsaw and circular saw's batteries are on there last legs and I quite fancy a cordless hedge trimmer so was looking at replacing the lot over time with these One+ products.

The thing is, you purchase the tool then match it up with a common battery.
Sadly these batteries range from (oem) 35 quid for a 1.3Ah one which I have upto around 60 quid for a 5Ah one hence wondering if semi decent pattern ones are available

When you say that they are "on their last legs", just how does that present itself, limited/low capacity, low power or just won't accept a charge?
How old are they? There may be a cure/means of extending life.....

They are very old B&Q ni-cad's Ron.

I've collected 6 batteries over the years.
Some batteries will not even charge now, some take forever to charge and hold the charge for about 15 minutes.
One or two even get hot enough to cook on when charging / using hard 
Tbh, the tools are a good 15 years old so they won't be helping the situation either

I had the same thing with my old battery drill.. bit the bullet and bought into Makita with a twin charger, 5Ah and 3Ah battery. The batteries are always the expensive bit and once you're in, you have to hope they don't kill the format before you've collected the full set of tools!

With that sort of age, TG, I fear there is no cure.  Still, it may be worth a try.....
What often happens with NiCads is a crystal dendritic growth forms internally which effectively shorts the cell out, hence it will not accept a charge and can get quite warm.
A fairly drastic solution is to apply a voltage somewhat higher than the normal terminal voltage of the cell - BRIEFLY - to the suspect cell; a quick flash is all you need. The power source needs to be low impedance, and brief, so a capacitor of suitable size and capacity would be good.
Don't try this at home, children!

That's where the Ryobi stuff scores, as the original NiCad and current Lion batteries are fully interchangeable.


I find the cordless angle grinder particularly handy for small jobs, and the circular saw is more capable than my wood working requires.
