    Looking to replace Daily Driver Camry 2017 SE - Battery Type 24F

    if you buy online do they let you pick it out (to get freshest stock)? or are you stuck with whatever they bring to the pickup counter?

    Old battery and charging system

    what @eljefino said previously... it depends on the wear/failure mode. anecdotally, I haven't seen many automotive batteries develop shorts in normal use. I think maybe when I was a teenager in the 80's my 1976 Ford Country Squire 9 passenger wagon with a 400 V8 that got 8mpg and made 165hp...

    Please review these battery readings.

    So yes, it's true, a "marine deep cycle" battery is basically just a regular starting battery. Somewhere on the interwebs there's a guy who dissected both (that is, a regular starting battery and a "marine deep cycle" battery both of the same BCI group and both from the same manufacturer) and...

    Battery dies after 1 year

    you're experiencing what used to happen with my '98 grand cherokee. my issue was parasitic drain in the "courtesy lamp" circuit. pulled fuses one by one until the parasitic drain disappeared. removed the offending circuit's fuse permanently , now the battery is 6yr old and still going. of course...

    so many M1 versions now

    as a former product marketing slave I get it... it's a competition for shelf space, and product proliferation gets you more space. but it's so unnecessary and inefficient. we don't need 14 different versions of some company's 0W20 oil. are hybrid engines really that different that they need a...

    so many M1 versions now

    it's been over a decade since I've paid much attention to the composition of the oil I put in my cars (kids are a distraction). but when I was at walmart over the weekend I found all these different versions of Mobil 1... extended performance, high mileage, extended performance high mileage...

    Battery -- new testing at 12.41 v

    I believe this is the "Value" 24F rated 585cca? I have the same one that was 3mo old when I bought it, it measured 660 on my tester, and appeared to be the exact same battery as the "Plus" battery rated 600cca (which also measured about 660 on the shelf). point being - yes it probably lost a bit...

    Who makes these batteries, and which would you recommend?

    just to further clarify how to use/interpret these conductance testers.... you can't take a cca measurement with it and compare it to the rated cca on the battery label to judge whether the battery is still good, for a couple reasons --- 1) the battery's actual cca when new is never the same as...

    Who makes these batteries, and which would you recommend?

    I have 2 of these https://www.amazon.com/Automotive-100-2000-Cranking-Alternator-Motorcycle/dp/B0B9SKJJMC/ they're a few years old now. might be better/cheaper ones out there now. you can also get them cheaper on aliexpress they work well, but are best used for tracking performance/capacity...

    Who makes these batteries, and which would you recommend?

    on 2 of the grp31 batteries I bought at sams the stickers had obviously been removed - there were adhesive disks left behind when they put the new stickers on in a different location. but of course I didn't notice until I got them home. upon checking with cca tester sure enough those 2 batteries...

    Who makes these batteries, and which would you recommend?

    whatever you do, don't buy from Autozone or O'reilly... higher prices and older stock. if you need grp31 Sams club has an East Penn beast for about $120 (I have 3 of them). or just get the 31 or 29 from walmart and call it good... but always get fresh stock... and check to make sure the didn't...

    Poor Quality Batteries from COSTCO

    for several years I was convinced Costco batteries were bad and were failing after a few months. after about 4 warranty replacements I finally decided to check parasitic draw on the 1998 Jeep GC, and sure enough it was draining the batteries dead while it sat idle. so I tracked it down and...

    Walmart Battery - failed cell

    you mean you paid them to test the battery? and then they charged it while still in vehicle?? while I'd assume any testing/charging equipment they use is idiot proof, I still wouldn't let a walmart employee touch my car. while it's doubtful anything they did would cause the A/C electrical...

    Slight hesitation while starting car

    I had the same problem with a 99 maxima. starter performance degraded slowly over a couple years, then one day wouldn't crank (albeit with some 200k+ miles). I swore it was the battery, but nope. replaced the starter with a brand new OEM unit and it was night/day difference in cranking power I...

    Great battery shopping experience at Sam's Club

    after the battery sits for several months on the shelf they peel off the date code sticker and replace it with a new/current one to make the consumer think he's getting a fresh battery. ideally they'd charge the battery when they do this, but I doubt they do. so how do I know this... I bought...

    Charger Voltage Too High

    the debate over battery resistance and ohm's law reminds me of undergrad EE lab. here's how I remember it... you can't really apply ohms law to a charging battery, at least not in a way that can be compared with the concept of battery internal resistance under discharge. these are 2 different...

    Best Battery Brand?

    the best battery is the one that is freshest, regardless of brand... then factor in $$ and a fresh Walmart Value battery is without question your best bang for buck ("fresh" meaning you bought it within 30 days of manufacture)... but if you like the warm fuzzy feeling that a 3yr free replacement...

    Great battery shopping experience at Sam's Club

    you can't be Sam's scan & go it's the one reason I rarely go to Costco anymore. However, my local Sam's has a nasty policy of swapping date stickers on their batteries (or perhaps their supplier does it??). I found this out the hard way but there's really no recourse. Just reinforces the need...

    Do you leave your battery charger continually connected whenever your vehicle is at rest?

    @gathermewool nailed it. the OP doesn't drive the vehicles enough to keep the batteries sufficiently charged. ask me how I know this (3 new batteries in 4 yrs on a rarely driven brand new minivan). so yeah I now keep it on a charger whenever it's not being driven. and my other vehicles too...

    Battery trickle charger?

    I really hate to promote Chinese knock-offs, but you can't argue with performance and value... the absolute best charger/maintainer I've found is https://www.amazon.com/FOXSUR-Intelligent-Automatic-Maintainer-Batteries-Blue/dp/B088QCXNMY/ why do I like it? It holds 13.6V even with a modest load...
