Replaced our battery yesterday with a Supercharge NS60 battery for small cars for $141.75 - not bad considering it includes a 40 month warranty…
(Nice thumbnail BTW)
40 months woooooo reckon someone can give me money to fix car and do a lot of things like buy myself a lot of expensive things I deserve it,
Had a Supercharge battery barely last 15 monhts. Then I read the warranty and it said they will only warrant a battery AFTER they have received/tested it and deemed it faulty.
So what, I'm supposed to wait a week or 2 before they evaluate it and how do I start my car in the meantime??
Didn't even bother, bought a new century and it's going great.
Had a Supercharge with 40month warranty. But could not start the car after about 2.5 year, got a free replacement. Warranty was not extended, only 1 year left for the new battery. Now it is the 23rd month on the second, and I can feel the battery is not very powerful when I start my car. Do not know how long this battery will last. But I will not buy this brand again.
Doesn't sound good!
My battery from factory is still working after 5 years lol, honestly expected it to go by now. I didn't select the thumbnail it's just the one that poped up! Don't know how to change it lol
30 mins of driving to recover battery from the loss of voltage from startup (not just stop start). 1 hour of relatively constant speed to recharge fully, although this depends on how good your alternator is and how many other auxillaries are running. These are general guidelines.
Short trips affect batteries, so a maintainer is worthwhile if that's all you really do (even a 2.5w solar maintainer for a small car battery, or a 5w panel for a larger Ah battery).
Every 3 months throw the battery on a full charge from a proper battery charger to wake it up.
Check your alternator is running within spec and there are no connection issues from corrosion etc. Ofc investigate other possible causes of charging/maintenance issues if necessary.
Maybe throw some cadmium additive in your next battery to help you out a little. They give you another year warranty on top of your already new battery warranty. Inox mx2
I use century and exide batteries. Bunnings always has good value extra HD exide batteries they can special order (check century battery cross reference PDF online).
I did know how to maintain a battery. As an electronics engineer, I even designed a power supply and charging system for a RMS project. An exide battery on another car had lasted for 8 years. It could start my car with no issues before I replaced it. Just because it was too old.
So you think Supercharge batteries are the issue?
Marshall have owned Exide since 2013, but who knows if they're making them differently or using different manufacturers. I can vouch for Century and Exide, just my experience.
I've had no problem at all with SuperCharge batteries.
But then again I don't do short trips, and also during lockdowns I used a C-tek charger once a week to top the battery up.
That's the key to making a battery last a long time. They don't like being left in half discharged states.
Every battery I've had has always done 6+ years easy.
Pretty good price for this common battery: https://autobarn.com.au/ab/Autobarn-Category/Shop-our-Full-R…
Bought the MF55B24L back in 2017 and still starts the car fine now. Last service mechanic advised the battery failed a battery test and will need replacing soon. Replaced it with the same battery and hopefully it lasts another 5 years.
Stuck the old battery on a charger and its still holding 14.5v
It didn't fail a battery test, it failed a rated battery CCA test. I seriously doubt the mechanic used a load tester on the battery.
Example pulled from online:
A battery should be big enough to allow reliable cold starting. The standard recommendation is a battery with at least one Cold Cranking Amp (CCA) for every cubic inch of engine displacement (two for diesels). You can do an engine cc to ci conversion
If your battery is still above your needs (as tested) it'll be fine as long as it still holds a charge. Its nice to have plenty of CCA reserve capacity though.
Generally I just replace when the warranty period is up after I've installed it. Solves a lot of potential headaches and stops your charging system from working itself to death (helping other things fail before their time).
