DAN’S MAZDA RX-8

The lockdown has taken another victim as the RX-8’s battery becomes the latest part to succumb to 18-months without use

-

It’s official. Cars don’t like standing idle. They long to be let free to roam the open road and gulp down super unleaded like Gazza on a gin-fuelled bender. Proof of this comes from the RX-8, which has pretty much sat untouched since March 2020, and is now beginning to protest its enforced exile with various gremlins throwing spanners into the works.

First it was the oil metering pump which went kaput and needed replacing with a secondhand alternativ­e, and now it’s the battery that has given up the ghost. Drat!

We had our doubts about the vitality of the RX-8’s battery for some time, as it first showed that it wasn’t feeling at its best way back in the middle of last year, when it refused to start one day. However, we simply put that down to a period without use and slapped on our trusty CTEK charger to get things going again. A few hours later and things were looking good, and we tried to keep on top of periodical­ly starting the car and running it for a while to try and keep the battery happy and alive.

Unfortunat­ely, this wouldn’t last long and eventually the periods that the battery would actually hold a decent charge were getting shorter and shorter until even daily use became impossible. This was partly due to the hotter summer temperatur­es, that actually speeds up the chemical reaction inside the battery causing it to discharge faster. This means that the battery gradually gets weaker, until the winter, where it needs a bigger hit to get the engine started and will likely fail. If you think your battery is not as strong as it usually is, then try a charger that has a reconditio­ning cycle. If this doesn’t seem to do the job, get it checked out with a free battery check from the likes of Halfords, as its better to get a replacemen­t when the battery is on its way out, than get stuck when it has completely died.

This seemed to be the case for the RX-8, so we got on the blower to battery specialist­s Yuasa for a new one. A YBX3030 was deemed the way to go and was sent out with next day delivery. The £128.02 battery is good for 30,000 engine starts and 630 cold cranking amps, making it ideal for the RX-8’s Renesis rotary engine.

Swapping the batteries over is a piece of cake, simply grab your 10mm spanner and remove the terminals before reversing the process with the new one dropped into place.

The RX-8 now has the power to start on the very first crank and is back in business. Nice one Yuasa!

Until next month! ■
