Well worth the higher price

My previous, cheap battery tester accomplished nothing. This one is versatile and accurate. Since one uses this tester by holding electrodes in both hands and touching them to the battery, I'm having some trouble keeping the battery still, since my desk is not perfectly level. Somebody more inventive or practical than I am will no doubt find the solution.

Pros
  • ★ PORTABLE & EASILY USE: A versatile digital battery voltmeter that is easy to use and remarkably handy size. No need to insert your test battery into any bays, just selecting the corresponding voltage via the rotary dial and then connect the contacts well through the test leads and the digital checker will quickly provide you a reliable and accurate source of energy your test battery.
Cons
  • The battery tester may not indicate the percentage of charge left accurately.
