Amaron battery

[LOLZ]

But the thing is, they almost always fail without warning. It may be "fine" a few hours earlier but would be dead the next time you use it.

The unpredictable failure mode is worse than product having a designed with a service life not much longer than the warranty.

speaking of heavy handed maintenance...

when one cell dies the whole battery dies. typically the cell starts dying when it goes a bit lower than the rest when you check with hydrometer. when left unchecked the cell gets sulfated and the whole batt cant function even when the rest of the cells are good. to correct the imbalance you charge at 15.0v. the full cells absorb the overcharge by boiling off while the low cell gets up to full.

as for motolites yeah they're junk. never buying one again

Well, can't do that without voiding the warranty. You can only tamper with the seal after that. However, the damage is probably done by then. Batteries of old had exposed inter-cell conductors so you're able to at least test the voltage on the individual cells.

No I mean since you bought the car nun May lang so factory battery should only have 1 year warranty from the dealer.

Yeah, I get that. But I am doing this to prove to myself whether or not this battery will last beyond that. I am shooting for 3-4 years, at the least. Let's see if I'll get anywhere near that if I pampered it.

Yes it is. And it often happens in the most inopportune time.

So even if you decide to change it before the expected end-of-life, you're not even sure when that would be. And so you adjust by changing it way earlier, and then you realize that you're not getting your money's worth by doing that.

As a side note, I stopped using Seagate HDDs more than a decade ago because their failure mode, as per my own experience, is 4/5 times, abrupt. It was working with no signs of imminent failure one day, but would suddenly not show up on your computer the next time.

WD on the other hand, again as per my own experience, fails a bit more gracefully, giving you enough time to move your files or take preemptive actions. Though I backup all my PCs now so this has become less of an issue. Sorry for the OT.

.

yeah by the time the warranty expires there's definitely some imbalance and low electrolyte going on, thereby ensuring that it won't live a long life it's a bit of a scam really.

best thing to do is to throw the warranty out and start doing the interventions early like within the first year. if the CCA readings are healthy then there's no reason to believe that the battery will fail prematurely so go ahead and void it

:

years ago, we replaced only the bad cells, leaving the healthier cells intact.
after a while, the so-called healthier cells would die.
we concluded that it ain't worth the piecemeal replacement.
doble or triple pagod mo, for a measely tipid...
we have to learn to price our time and our pagod and effort.

if i wanted to, i would open mine to check and refill if necessary. i figure, i have nothing to lose and much to gain.
based on past experience, kasi, my battery's warranty would have long expired, before the un-opened battery also expired.

Amaron is just way better then Motolite for the same price. Ang layo ng performance and longevity. I won't use Motolite again unless out of necessity.

[Dr.Kamiya]

There does seem to be an ongoing smear campaign against Amaron. If you look at FB there's going to be some random off-topic reply that hints at its... explosive nature even when it's not germane to the discussion.

[oj88]

I think it's the excessive buildup of hydrogen gas is what caused these batteries to potentially explode. From what I am seeing, this seems to happen, more often than not, near the battery's end of life. This is usually when some of the electrolytes have evaporated, leaving parts of the lead plates exposed. This condition apparently accelerates electrolysis in that cell, producing more gas than normal. If there was truly a defect on Amaron batteries, it could be the way the valves were designed. It is possible that they are too restrictive in letting gas escape, hence, when the gas buildup is too much and has nowhere to go, it gets catastrophic.

It is then prudent to check the water level in your battery, maintenance-free or otherwise, to make sure that all plates are sufficiently submerged in electrolyte solution. I'll do the same on my current Motolite around when the warranty expires, 8 months from now.

To Amaron's credit, there's probably only 2 or 3 such failures that's been shared online. I could be wrong but I haven't heard of repeats in at least the last few years. Maybe they have quietly corrected the issue?
