Hi Norm,

For me once I start to think of spending $$$$. on a mower ,I think I'd rather buy a second hand Tractor with a slasher.

Yes the batteries can last a long time when the equipment is regularly used ,it's the winter times of Infrequent use that
can be a problem .

As we know when a battery is not charged regularly, it can fall to a low state of charge, which can lead to sulfation and reduced capacity.

These days people can use Solar Trickle Charger when equipment sits around not being used or use a battery maintainer.

I have always thought someone should make a battery that never needs replacing ,one that just requires recharging.

Batteries that Never Die

Scientists at the University of California are working on nanowire batteries that will never die. The gold nanowires are a thousand times thinner than a human hair and sit in a gel of electrolyte to keep them from breaking down during recharging. They have been tested recharging over 200,000 times over three months and showed no sign of degradation.

Calling them "never die" is misleading though ,while nanowire batteries show great potential and advantages.They may offer significantly improved lifespans and performance, but they are not entirely immune to degradation over time. Nanowire batteries are designed to have significantly longer lifespans compared to traditional lithium-ion batteries. This is due to their structure, which can mitigate issues like dendrite formation that lead to battery degradation.


I hear there are experimental EVs that will charge in a few minutes and do over 1000 miles on a single charge.

This was possible thanks to aluminum-air battery technology that uses oxygen from the air to fill its cathode - making it much lighter than liquid-filled lithium ion batteries - to give the electric car greater range.

Many industry analysts believe that with current trends and advancements, we might start seeing EVs with ranges around 1000 miles by the 2030s sold to the public, but this timeline could vary based on technological breakthroughs and market factors.

Cheers
Max.
