Not in a hot car they don't, and they are less stable when they are
damaged, be it heat, overcharging or left undercharged.

The ones without batteries use super-capacitors that charge up very
quickly and release a large amount of energy over a relatively short
period of time.

I keep a pair of jumper leads in my cars.

I think I've used them 5 times in 10 years, four of those times to get
someone else going.

Just last weekend I left my headlights on all night and flattened the
battery (completely).

The car manufacturer had neglected to install a warning device to
prevent this.

The RACV guy had one of these small gadgets and jump started the
thing. However it was much larger and about the size of a small shoe
box.

On advice I had to charge the battery overnight to ensure a full
charge.

Since I have survived the ordeal, I offer this advice...

1/ A battery is a consumable; change it every 3 years.
2/ Do an overnight charge every so often, especially in winter.
3/ Ask some who has the 6000mah "Power Bank" as to its value.

Sure they're bulky, that's a given, but they're safe to leave in the
car, don't need frequent recharging, have USB and 12v cig sockets, a
work light, and will pump up tyres.. and of course start yer car!

I've had the same one for 15 years and it's not.

Absolute bullshit. A car battery is no different to any other automotive
component in that it has a finite life and should be changed when it
needs to be changed. Preemptively changing a battery is a very good way
of throwing money down the toilet.

> 2/ Do an overnight charge every so often, especially in winter.

If your car's charging system is in good order there is absolutely no
reason whatsoever to ever do this.

> 3/ Ask some who has the 6000mah "Power Bank" as to its value.

"Power banks", "jump starters" or whatever you want to call them are no
different to any other tool in that you need to use the appropriate type
for the task at hand. That should be obvious to anyone.

What is *also* obvious to anyone is that you should *not* be giving
people advice as you have absolutely no idea what you're talking about.

Incorrect and a waste of money.
I've had a battery in a Mercedes last 18yrs and another in a old Holden
V8 last 14.
Most last more than 3yrs.

> 2/ Do an overnight charge every so often, especially in winter.

Only necessary if you don't drive the car often or far enough to keep
the battery charged.

how coincidental to be discussing this. big windstorm here in Melbourne
and power off so I used it to recharge the mobile. It's an older model
with no USB port so used the 12v cig socket with an adapter.
