Testing Eneloop with multimeter

[Billcoke]

I've a few old Eneloop in my drawers, wanted to use a multimeter to measures their capacity in mA. According to some forums, using multimeter to test the batteries can cause the eneloop to burn, is that true??

How to test mA?

Or mAhr?

leaving the multimeter on ammeter mode to measure current is essentially shorting the batteries. I am saying this from the POV that for an ammeter to do its job of measuring current flux properly, it has to have near zero resistance. (recall, ideally, ammeter has zero resistance)

For battery alone you can only test voltage (V).

u have to use battery analyser. those work by charging the battery til it's full, then discharge and measure how much charge the battery has held.

 

i'm using a maha wizardOne analyser. can buy from east gear. one word of caution, maha imedion batteries suck. i heard better reviews for eneloop. generally i think sanyo rechargeables are the best, followed by sony.

 

avoid the maha imedion batteries, but can consider the battery analyser. i used it to determine which batteries to throw away. supposedly it can also condition your batteries but i'm doubtful as to how well that turned out, since my imedions deteriorate quite fast even under rather light usage. maybe cos i always drain the battery fully

Bro, thanks all for the feedback. Will be careful w the battery and not to short circuit them.
