I use Energizer lithium in all my meters, Fluke 289 included and never had a problem. They last a long time and no leaks so far!
Panasonic Eneloop (Rechargeable NiMH) works well with zero issues to report.
I have heard quite a few people recommending the Eneloop rechargeable batteries. I will grab a couple of packs and try them next battery change.
Any battery, be it a good rep/bunny endorsed/high price
or cheaper than cheap flaky packaged no name/Blah Power/ two dollar type
or 1000 shot rechargeables
are only good batteries to buy if they don't leak ! especially if not used and or just past their use by date.
and hang the so called 'performance' and 'longevity' advertising BS,
which doesn't wash when the leaked gunk has trashed an expensive multimeter
or worst case scenario: killed off junior's FAVORITE
shutup TOY
= parents
I've also seen rechargables leak that were left for a period and discharged
and up to a few years ago, crapped out Enerjizzer alkalines used to be a guaranteed find in big dollar multimeters, especially Flukes,
and DSLR cameras and bells n whistles flash units and slaves etc
Big dollar lithiums have leaked in new sealed packages stored in 'ideal conditions'
just when called in for backup duty in a flat camera, out in the middle of picturesque nowhere..
fwiw I've seen a lot less instances of Duracell alkalines crapping out, staying intact years past their expiry date
The spent 9 volt ones in smoke detectors are handy as multimeter batteries, as most meters will work fine at 8xx volts
Hoping that the leaker trend dies with Eneloops, time will tell
and then again, which Eneloops will hold up better? The real deal or the knockoffs?
