Rightfully all the tests must be performed so that that will give me the ability to inform the client, if there is a potential problem with their electrical charging system that may affect the battery's warranty. I understand that many will not conduct such test for whatever reason they only seem to know.
What a lot of dealers are saying about Amaron is true. I don't think Amaron will be the only battery suffering the same fate. When well known brands suddenly starts coming out with different colours, different designs out of the blue, then something is happening already. The crux of the problem is our ever depreciating currency. A weakening currency cannot command high quality goods & services. Period. So to maintain the quality, even more depreciating currency will be needed BUT wants to pay more ? So to maintain turnover, price is either reduced or maintain but at the expense of quality and that is what the dealers are seeing now. Conversely, if our currency is strong, we all will be enjoying better quality batteries, that's for sure.
Marathoner Max has always produced the results my clients are looking for. However my personal experience with my own new vehicle, I noticed that although my Marathoner Max was still showing a Good Battery status on both my testers, certain electrical functions became inoperative lately. So I quickly switched to an even higher capacity battery that twice the price and now everything is functioning as it should. Herein lies my problem, the manual did not specify the battery type and size but asked to refer to Service Center. So is the Marathoner Max bad ? Nope, just that it is not suitable for my vehicle which requires a battery with higher Reserve Capacity and Amp hours. I have Marathoner Max in my other vehicles and they are performing within parameters, so no problems there.
I believe that once you have had the battery test conducted and if it's a Replace Battery status, do a battery replacement and your Starter should start up immediately without any delay. If there is any delay, then the Starter Test will detect something. YouTuber AMD Toyota Master Technician advocates buying original Starter Motor and Alternator from the SC, which I agree but I also know that over here, there are no new alternators from SC. I don't think there is a problem with the Starter Motor, what I suspect is that you have a weak battery and now the Starter Motor is struggling slightly to turnover the engine.
After visit 2 battery shop, I really doubt how accurate the tester is?
1st shop device, Konnwei KW208, SOH 77%, SOC 100%, 385CCA, 12.96V, R=7.57m (Good Battery)
Cranking Test, time 3320ms, Max 8.76V, Min 7.48V (Cranking Low)
Charging test, loaded 14.42 (Charging Normal)
2nd shop Micro-200 Pro, Healthy 54%, 405CCA, Charge 98%, 13.02V, R=7.36 (Replace)
Cranking Test, 5608ms, 9.64V (Normal)
Then they use another device, SOC95%, 421CCA
Conclusion both shop also say this battery still usable, come back and check after few months.
So i take the average reading for both shop. The boss say my cranking meter dim issue may due to earth or grounding issue of starter or old car.
