BATTERY in Klugar 4 years old

[Klugar BATTERY]

I left my teenage son in the car with his door open for a few hours, so the interior lights were on. I had turned off the radio, as he had his phone. 

NO  START. The car was brought brand NEW in 2020. Lucky husband had his car and jump start for me.

Then AGAIN a month later, I left the boot open to pack for a few hours. STUCK on a Sunday. Battery DEAD

My Klugar has done 30,000 Kms

This indicates that the battery is getting due for replacement. As a general rule expect 3 to 5 years for the lifetime of the battery. 

There are a few posts about what batteries members have selected in the past.

Recommended Century battery models are NS70LX MF and NS70L MF for Toyota KLUGER. 

Last battery that I purchased was a SuperCharge brand truck battery model MF80D26L which will also be suitable for a Toyota KLUGER.

Just happens that my other Century battery which is 5 years old is currently being recharged so considering whether I really need to get a replacement.
