Battery Or Not The Battery

[Lexusjase]

Hi,

New IS200 owner here.

Just a general question, regarding my cars Battery. I notice on the dash of my car that the volt reading for my Battery is just over 9 volts.

The car sometimes requires me to push the gas pedal to start up. Is this because of the Battery or maybe spark plugs??

Thanks in advance

Jay

Hi and welcome.

This is where it should be before starting

And this is where it should be when the engine is running.

It shouldn't struggle to start. When was the last time the plugs were replaced?

Yeah that gauge picture looks just like mine pre start and during.

I've had the car just under a week so re spark plugs I couldn't tell you when they were last changed.

So I'm going to change them this weekend for some NGK ones which seems to a popular choice for alot

of Lexus owners

Cheers

Yep can't hurt to change the plugs. I run NGK iridium. The plugs must be iridium!!

Denso SK20's are OEM

how old is the Battery?with winter on its way anything older than 5 years and would consider changing it.

I'm not sure, as I've only had the car a week. It's had a Battery check and all seems fine.

Think a Battery is next on the to do list though.

Yeah last winter mine started to struggle to start. I didn't do anything then I got a flat Battery. I think the Battery I took out was the original lol.... Can't hurt to change the Battery mate :)

Just swapped my OEM Battery today for a new Bosch one. The old one would start the car and the voltages were within spec as per Chris' photos, but the engine was starting to turn over much slower than normal, especially if some electrical stuff was on (ie: sidelights).
