content: A question for owners who can give real world answers....I am waiting on my new meter arriving and have seen loads of reviews and stuff on how battery greedy the 289 is. I won't be a heavy user using it all day every day, just light use doing simple hobby stuff. I will use the logging feature sometimes too but not for days at a time, just a couple of hours at a time on the odd occasion. If I was an EE or spark or something using the meter every day i'd get the re-chargeable ones for sure.Is it worth getting 12 rechargeable batteries so I can have 6 charged as 6 are in use or am I worrying for nowt?

content: It's easy enough to turn the meter on and off with that soft green power button, if you don't mind the boot times (I don't)I've been using a tired set of cheapie batteries since day one when I bought it used, still goingIf you're going to be doing a lot of logging, I'd go for two sets of Eneloop batteries and a good chargerWatch out for that round black screw thingie that unlocks the battery compartment, it crumbles and fragments to rubble if stiff and used a few timesAnotherDumbass Design Awardcandidate...I doubt the silly thing is even available as a spare part, and doesn't cost the price of a new backor meter LOL

content: Thanks for the heads up on the weak azz plastic screw! I'll watch that for sure! You'd think Fluke would have a better design than that right? Just shows even the best brand names will cut even a few pence from the price of building them.I ordered a 12 pack of the AA lithium batteries tonight so that should get me started Ha Ha! I'm sure it says it comes with batteries included too so we'll see! If it eats through 18 too quickly there will be another "used" one up for sale sharpish!I think i'll be classed as a fairly light user compared to some so i'm hoping that helps too battery wise. I think all my meters are still on their 1st battery to date so hope this one lasts just as long as the others. This will be the first meter i'll have owned that doesn't take the square 9v battery.

content: Quote from: blueskull on February 19, 2018, 12:20:55 amYes that's the same ones I got, good to hear they are alright. This will be the best meter I've owned so far, I've wanted one for a wee while now. I have the Fluke 177, Extech 505, Brymen 867s and a couple cheap meters but they are all good on batteries. Looking forward to the 289 arriving!

content: Quote from: Terry01 on February 18, 2018, 05:08:17 pmYes, definitely. And also DO NOT use alkaline cells.Learned my lesson very well ->Rotten Energizer Alkaline cells in 2013 ruined Fluke 287 contactsAs mentioned, this Fluke 28x never powered off, as it uses soft power button, hence if it has the rotten leaking supercap, it will drain the batteries even it fully off.Regarding using LSD NiMh cells, especially you mentioned you won't use it every day as I do, this thing last very long, just checked the battery indicator since I charged them > 12 months ago, it still doesn't complain with low battery indicator. And I doubt you will ever touch the spare 6 cells for months if you don't use the meter often.My 287 with Eneloops.

content: Quote from: Terry01 on February 19, 2018, 12:11:15 amIf you inspect the black plastic lock screw carefully, you can make it easier and lighter to turn with just a little tiny "plastic friendly" grease, and once greased, you can lock & unlock turning that screw just using thumb finger's nail like mine.As the lock screw is made from plastic, sometimes its stuck hard and fitted very snug at the battery case, and usually at most cases, once people had trouble turning it as its so snugged, usually they will use a metal screw driver to turn it forcefully, and as you know, plastic never beats metal.

content: Advice taken!At least you found your meter quite quick before any real damage was done. It would have been very easy for you to have still been using your meter for even a year or 2 not knowing the batteries were leaking. I take it your meters are stil going well now? Great deal by the way!!As soon as mine arrives i'll swap the batteries out for the lithium ones.

content: Quote from: Terry01 on February 19, 2018, 08:47:25 amYeah, lucky me too. Both are working fine, love it, its just not my everyday DMM as they're big and boot quite slow which don't suit me.But for logging, especially in handheld portable form, and also doesn't need PC/laptop/smart phone to view the log chart, it is very convenient, one of the best imo. Also this 287/289 series are like a really high resolution, but low bandwidth portable handheld scope.Few examples I've posted here in this forum of it's really handy logging feature ->Example charts for 8 hours log and it can be zoomed down to secondsIt was done in order to test on a newly installed air condition back then years ago.->(Fluke 287 recorded temp chart for 8 hours)(Warning, big photo).Or logging the capacitor leakage after its been reformed for few hours->Use 287 to measure cap leakage for hoursRegarding alkaline, another bad story ->YARAQuote from: Terry01 on February 19, 2018, 08:47:25 amWise move.

content: I would not trust any batteries, especially in a 6 battery russian roulette scenario like a big dollars 289/287Just one of the six that missed quality control or a bad batch has to leak, and game overHave a routine in place or phone/calender reminder to check all battery powered test gear every 6 months,preferably during the coldest and hottest week if the work space is not temperature stableRechargeables may be a better bet seeing as you have to pull them out more frequently...and risk breaking that cheap@$$ crappy retaining screwAny clued members know where I can get one (or box of 10!) , preferably in Australia, and wth it's called and a[[ don't hold your breath]]elusive Part Number?Hoping it's not Fluke Part Number#SOL-BUYx1 New289Meter

content: Thanks mate, good surfingunfortunately it's paypalonly and not a local sellerI'm saving the link in case I get that peaved and call in a favor from a friend with paypalThat said, I wasn't aware that the same part fits "83V, 85V, 87iii, 87V, 88V, 787,89-4(89 IV)187, 189, 789"The pair on my 87V look smallerWill have to check that out asapIt is a stupid design and a guaranteed 'Spot The Achilles Heel' winneron an otherwise decent pro meterEDIT: Actually, if they use TWO to hold in a little 9 volt battery on a Fluke 87Vyet implement ONE to hold in a 6x AA batteries on a 289Someone asleep at the CAD wheel ?

content: Quote from: Electro Detective on February 20, 2018, 08:53:55 amNo prob. I am sure that same seller has the 87v door as well with the 2 plastic screws but I think it's about treble the price! It's a shame like you say to put such a cheap crap part that is sure to fail on an otherwise decent meter! Just shows even the mighty Fluke drop the ball sometimes right?Maybe if one of your buddies or someone local to you on here has the 289 and maybe halves in on the postage with you it would be worth getting postage combined on a few? Otherwise it's an expensive "cheap crap" part right?Hope you get something sorted for your part buddy.
