Until then, I was using handheld testers three francs six sous, which qualifiaient me excellent inoperative batteries in some devices. With this professional tester, I understood: - That alkaline batteries for cameras, cameras, and other energy products were not powerful enough below 60% load; but enough to power a light bulb, an alarm clock, in short, any item little greedy. - That even 10%, a battery can continue to serve in those low-power devices ... - And so I was able to sort my batteries based inventory of my needs. The device is reliable, but sometimes needs to be "hot" to give good measure. This is the best price / quality ratio on the market, in any case at Amazon. Above is really expensive; below, it is only gadgets and company ... Only downside: it does not seem designed to test the low-end AA & AAA batteries (salt) and high end (lithium). Nevertheless, I highly recommend this camera!
