[Electronics-Talk] Accessible battery tester?

[Aaron Spears]

Hi.


You could try one of the talking digital multimeters, like this one:

ANENG Pocket Multimeter Voice Broadcast Electrical Tester 4000Counts Ohm 
meter for AC/DC 
Voltage,Current,NCV,Resistance,Continuity,Capacitance,Diodes,Temperature 
Meansurement,Volt Meter for Automotive: Amazon.com: Tools & Home

For that, just push the big button until it says it's on, and then touch 
either end of the battery with the leads. It'll say dc voltage 
measurement 1.61 volts, etc. A dry cell AA or AAA is considered good if 
it has 1.5 volts. Voltage does drop on these as capacity drains, so this 
is a reasonable way to determine their state. If it's rechargeables, 
Lithium don't really have a voltage drop so that's probably out, but Ni 
MH do, but their max volt is 1.2v so if you have one that's at 1.38v 
it's a really good one.


Caution do not do the leads on either end of a battery test with the dmm 
set to dc current measurement! Set it to dc voltage measurement or just 
do it in the default mode it has when you first turn it on. When you set 
current measurement the battery will dump all its power into the dmm as 
fast as it can go until the dmm is toast or the battery is, or worse.
