Amaron battery

[oj88]

Looks like 32-bit integer overflow divided by two, caused by the divide by zero (from 0 ohm internal resistance). Maybe there's a minimum resistance in the formula which is why it's a tiny bit less than 2147483648.

I guess the underlying circuit that measures the resistance conked out and passed zero Ohms to the unsuspecting app. If there was anything I learned from my EE subjects is that, any and all batteries, regardless of chemistry, has an inherent non-zero internal resistance. The software should have logic to throw an error if no resistance is sensed, but I guess they never expected that failure mode. It was a relatively new product when I bought it. Being an early adopter, I took a gander on it.

Anyway, the manufacturer (Lancol) took it back from me so they can do post-mortem on it daw. This was in 2020 and I don't know if the same units being sold now are more reliable.

haha but they're good enough for non-pro use. i compared to the casa's Midtronics and the results were close enough

Thanks. Good sharing on battery tester for non-pro [emoji16]

I used Amaron EFB before but shifted to Panasonic and Varta EFB.

Panasonic at 2yrs 2 months now installed on Subaru with I-stop and still at 99% tested at casa.

Varta is relatively new at 8 months from previous Amaron installed on Mazda with i-stop that lasted 18 months. Will see how this EFB battery perform.

1 noticed that my Amaron Pro is already 20 months old, so I decided to charge it to test it's health. I was surprised that it started at 40% battery level but quickly went to 95% in 15 minutes. In comparison, my other Amaron Go of the same age showed 95% when I charged it. After 2 days in the garage, I charged it to check how much it retained. To my surprise, charging started at 5% but went up to 50% in a few seconds.Then in about 15 minutes, it was back at 95%. Is this normal? I don't feel any symptoms of a weak battery yet. I'm going to have it checked by the supplier on Saturday and it's still under warranty till 24 months.

back in the days of analog battery chargers,
i noticed that when the battery has very little viable plate material left,
they would seemingly get fully charged in a few minutes only, as evidenced by the needle.
but they did not hold the charge long enough. we would hope that we could start the engine immediately after charging, before the battery lost that charge.

i think your batteries are dying, po.

I hope it doesn't die until I have it checked this Saturday [emoji1696]

You need a proper battery analyzer or tester to accurately measure its state-of-health (SoH). The internal resistance is the main indicator for SoH.

And unless the battery was subjected to frequent or high depth-of-discharge (DoD) greater than 50%, 20 months is nothing for an Amaron. If it was taken cared of, 20 months should put it roughly just 1/3 of its lifespan.

Mine lasted a little over 5 years (~60 months).

Magkano ba talaga presyohan nitong Amaron for DIN100 CCA of 740?
Grabe pricing when I inquired from FB market place, nasa 12,500.

[H1Tman]

My Amaron Hi-Life is close to 3 years old. No problem so far.

Alam ko mas mahal talaga mga DIN-standard batteries. Haven't looked up why.

But FWIW, a quick search yielded a DIN100 Amaron for about 10.3k on Shopee. Caveat emptor nalang and try Lazada, as well as Amaron's own hotline.

Taken cared of in what way? Frequent charging to 95%? I think the problem is that the car makes frequent short trips daily. Minimum would be 2 trips * 12kms, am & pm at 5 days a week (house office vv) and then 3 days a week, add 2 more separate trips at 12kms (hatid sa bus station) and 2kms (sundo outside subdivision).

Taken cared of in what way?

It's more of a blanket statement.... as opposed to draining it frequently from running accessories for any length of time with the engine off. Or if the vehicle has a parasitic draw (happened to me). Or, however unlikely, if the alternator isn't quite putting out enough oomph to fully charge the battery.... things of that nature.

Lead-acid batteries are happiest when indefinitely connected to a float-charger. Anything more (over-charging) and the electrolyte boils and dries out. Anything less (over-discharging) and it will accelerate plate sulfation.

To me, that's within the scope of normal use. You could fully-charge the battery every couple of weeks as schedule permits to keep it topped up as often as possible.

I have an SAE pigtail connector partially hanging out the front grill. Every weekend, I connect it to a battery maintainer/float-charger that's hanging off my garage wall. All these without opening the hood of my car. I'd like to think that this is one reason my last Amaron lasted as long as it did.... parasitic draw and all.

[papi smith]

Can you please post a picture of that pigtail? Is it ready to buy or DIY?

The SAE connector is just one kind of DC quick-connect. There are at least a couple more types, depending on what your charger came with. For example, NOCO chargers uses "X-Connect" (likely proprietary).

Hmmm, mukhang complikado, I attached the terminals to my batteries but the other end looks like it will need another connector for the charger as well.

Oh well, I guess I'll just stick to the standard method [emoji16]

It's straightforward naman. Not sure which part is confusing.

My battery maintainer already has the SAE connector and it includes the SAE pigtail as well as an SAE-to-alligator clip adapter.

[papi smith]

Yup, that's what I was referring to, you have a matching plug on the other end while I have the usual clips.

^I suggest installing an EC5 female connector because the booster battery bank comes with EC5 male, para kung totally ma-lobat, plug nlang ang booster battery bank. Or instead of SAE w/c is imited to 30Amps, upgrade to XT60 or XT90, wag na yun Anderson at pang dual battery na yun.

[Vodka]

the moment i park my cars in the garage i pop the hood open. the float chargers are always plugged in to 220v so i just grab the cable and connect the alligator clips directly to the battery terminals. yes i wired 220v outlets near each car

so my parked cars always have their hoods open. this promotes easy and frequent checking of oil levels, brake fluid, coolant, etc

Plus it deters cats from sleeping inside engine ...

[papi smith]

Ok, so what I'll do is charge the battery every weekend to prolong it's life. My question is, should I quick charge it till 95% only where it usually stops and takes at least another hour till it gets to 100% or always till 100%?
