would not worry about the drill, who made the battery is more important

Or the charger, if it had poor voltage/current/temperature control.

Nope, I installed 10 panels 20 years ago. all stuffed now.
10 x 80w panels that cost $900 EACH ! $9,000 for an 800w array.
Which would cost about $1,000 now.

There was a doco not so long ago about soalr panels, expected to have a 20 year lifespan, but were replaced in 10 years, because newer panels were a few percent more efficient. So they didn't even last their expected lifetime.

This may be the definitive summary of power requirements to run the equivalent of all of NZ’s light vehicles on electricity.
The total number of kilometres travelled by all light vehicles in NZ = 42 billion kms per year. This includes all petrol and diesel vehicles under 3.5 tonnes (including light vans) but excludes vehicles over 3.5 tonne, trucks etc
A Telsa Model S75 (75kWh battery) uses an average of 18kWh to travel 100kms
So if every light vehicle in NZ was a Tesla S75 we would need 7,700 GWh of power for them to travel a combined 42 billion kilometres.
NZ's electricity production from March 2020 to March 2021 is 85,700 GWh, sourced from a MBIE website but different sites can have varying values.
Charging enough Tesla S75 EV's to travel 42 billion kilometres will use about 9% of NZ’s current annual power production.
(Disclaimer: I got a C- for 6th Form maths, so happy for any corrections)

Give or take NZ has about 4 million light vehicles.
Motoring Industry data indicates 81,000 vehicles were registered in 2020.
If we replace new vehicles at 100,000 per year it’s gonna take 40 years to change the fleet.
Even if we replace the current vehicles at 3 times the 2020 sales rate i.e. 250,000 EV’s per year (5,000 per week) it will still take 16 years to replace the fleet.
Once they are all EV’s we need 9% of our current electricity production to charge them sufficient to run 42 billion kms per year. (unless they are all Nissan Leafs, in which case we only need 7% :-)
Within 16 years I suspect I’ll need a new vehicle and odds are it will be an EV….
Times they are a changin.

It is also highly likely within 16 years that Self Driving Autonomous EV’s (SDAEV) will be on the road.
If you want to go to work you send a text and 42 seconds later a SDAEV pulls up and takes you to work for a cost of $3. Then disappears into a lift to go underground into a basement with 20 other EV’s for storage and recharging.
Wanna car pool to work with a SDAEV ?, $2 each.
Wanna go shopping ? $3 and when your trolley is full a SDAEV pulls up and takes you home.
Kids from school ? You send a text and a SDAEV picks the kids up from school and drops them at nana's =$3, which compared to a colleague who has to rush out at 2:45pm to pick up 2 x 7 years olds and take them home is a dream come true.
Wanna play golf ? send a text and a SDAEV takes you there and disappears. Pissed after golf ? a SDAEV takes you home….
So it is likely we won’t want need 3 cars per household.
Then you can turn half the double garage into a bedroom or man/woman cave.
All that staff car parking and downtown parking is no longer needed.
Just a couple of dozen discreet and strategic underground EV storage and charging stations.
Want to buy something and have it delivered within an hour or so, you buy it on-line and a SDAEV delivers it.
Wanna send a parcel or important documents across town, text for a SDAEV to take it, you send the receiver a code to unlock the boot.
The EV's will even wake up in the morning and go park in places where they know the demand is coming.

LOL and where am I to find that sort of money, to by a new vehicle.

My mechanic said the same thing, it's not good for the environment.

Yes I would, if the tech was way advanced and safe to travel and batteries could be disposed/ recycled without damaging the environment.

Your mechanic makes his living fixing ICE vehicles. Does it occur to you that he may be a bit biased or at least ill-informed?

Where did you hear that drivel. The upgrade to push power north from the smelter i believe is still in the design faze.
