I sure hope the brand Amaron outperforms in terms of quality & lifespan, with proper care & maintaince. At least, it gives us end user options for choosing good batteries and supplier in maintaining and carrying the product line.
However I believe that a forummer therain01, said that Amaron unit after its warranty is showing signs of weakness already. That's the first -ve I've heard apart from all the +ves "So far so good."
Hoping that the averages would be a good one too, just as you've put it.
Have to make a correction on my previous statement, amaron under joint venture partnership with johnson controls, not part of johnson controls company. Varta is the one under johnson controls.
There are more external factors other than the mere battery construction.
If there are parasitic load, any high end battery will be killed within a shorter lifespan.
If usually go through a lot of uneven roads/high vibration areas, battery will have shortened lifespan.
If under high temperature (especially turbocharged cars), if battery located within the engine bay, also shorten lifespan.
If a lot of start/stop traffic, because not receiving long enough charge, will also shorten the battery life.
There are also factors like alternator and grounding condition, correct choice of battery size/load type, connection condition, faulty switches, bluetooth that can't shut down (some cars have this weird bug that will keep searching indefinitely because there are strong enough bluetooth sources nearby), etc.
Because if you're really "that" concerned about battery life, get an AGM and a proper lead acid battery charger. If you're really into the money, lithium based car batteries (super light and powerful but low reserve charge).
