I've read from several members posts about testing their batteries to determine if they need to be replaced. Can someone tell me what I need to buy and do they have it at Radio Shack? Oh yeah, how much does one of them boogers cost?
Also found this info on the Net:6volt lantern battery Test
10ma 4.5V +- .36
5 ohm load
0 -61% replace 0 - 3.66 volts
62 -72% Weak 3.72 - 4.32 volts
73-105% Good 4.38 - 6.30 volts[/b]
Energizer battery testers are intended to indicate general battery condition and will not predict battery life remaining. These testers are loaded voltmeters and use the following loads and minimum “Good” cut off voltages. Because of the chemistry of zinc air cells, these testers will not indicate battery condition.
BATTERY TYPICAL APPLICATIONS LOAD (Ohms) MINIMUM “GOOD” VOLTAGE
1.5V General Use 10 1.1 volts
D,C,AA,AAA Motor Drive, Photoflash 1 1.1 volts
6V Lantern 5 4.4 volts
9V General Use 250 6.6 volts
9V Photo Flash 15 6.6 volts[/b]
