Pretty sure thats a circuit protection feature on alot of battery operated tools these days

Could possibly be a crook protection circuit in a battery pack - I have one here that the cells all check out when individually tested and everything works right but with a bit of load on it the thing shuts of and the tool stops. Plug it into charge, and the charger says fully charged. Seems to work OK on light drains like a torch or a drill using a small drill, but on grinders or circ or recipro saws it shuts off virtually straight away.

Soldered connection between batteries breaking down??

Don't think so, they and the spot welds are all tight. The battery cells are all fully charged, the charger is saying charging, then charged, so it appears to be the circuit that has an issue rather than the cells. I have another circuit, but it's a serious pain in the arse changing them over and I can't really be bothered at this stage.

Thanks, good info! So is it possible to test the batteries to diagnose, or do I need to try the saw with different batteries?

Easiest way is try another battery thats known good, and see if that fixes the problem. If that isn't the solution, it is most likely the tool is the issue and in that case it could be a case of stripping the thing down and cleaning everything up. If it's the brush-contacts version, they might be not playing the game and I think this is relatively common in the scheme of things. If it's a brushless one, the simple fixes and most usual causes of problems aren't in the picture!

Not the OP's original question but my DeWalt 16inch leaks chain oil all the time and is a bit of a cunt in that regard

Hasn't put me off electrics as a small saw but will get a Stihl or Husky next time

Good point, I thought it was me being a messy bugger

Some battery saw manufacturers cover their arse by stating " drain oil tank when not in use", De Walt haven't placed this option in their spew?

I've searched and it is a known fault with the 16in saws so I'm stuck with it

If I have stopped someone else from buying this lemon of a saw (although it is great in all other respects) then that's a good thing - some say sticking a bigger O ring on the cap works but haven't tried

Next time I go for a cordless it will be a Husky or Stihl

Hey guys thanks for your suggestions which are all good but this thing gets wetter than a middle-aged woman at a Harry Styles concert

It's a design fault, pure and simple

Avoid DeWalt battery 16inch saws (hey! getr a Ryobi!) and buy saws made by people who know saws like Husky and Stihl

I've got a 18v Makita with a 10" bar. Goes very well within reason for its size, goes through most stuff easily, surprisingly quite grunty. Only issue has has been trying to get a spare 1/4" chain off the shelf.

I've got a 12" DeWalt, brilliant. In the hunting block we use Ryobi, also good.

Just watched it, interesting - I feel like the run times are quite short but that is probably because it was continuous running and not cut stop cut like a normal use situation. The recharge times seem about right, you kind of need three batteries if you want to replicate the use of a petrol saw - one in use, one charged and one charging - but after that you're taking a break and the cost is shocking!
