We have solar panels and a battery in the garage underneath the main part of the house. I would like to get a specialist fire extinguisher- which from reading appears to be Lithium-Ion Fire Suppressants.

I have looked on Amazon but to be honest not sure what is correct as none of them state the obvious (ie ideal for batteries for solar!). Can anyone send any links please?

And is there anything else we should fit down there- smoke alarm, heat alarm?

Thanks

Don't waste your money - if a lithium ion cell goes into runaway the toxic & corrosive gases vented off even before the fire starts will permanently damage your health seriously (or worse). Unlike extinguishers for normal fires, which are tested by operatives with standard industrial clothing, the lithium ion extinguishers have to be tested by people in full body protective clothing and self contained breathing apparatus even though the test areas are fully ventilated or even outdoors.

If it's not the li-ion cell on fire but just the standard electrical equipment in the installation then any electrically safe domestic extinguisher will suffice, water mist and ABC Powder being common
