Draper 72090 Dry Cell Battery Tester Review

In the age of rechargeable Nickel Metal Hydride (Ni-MH), Lithium Ion (Li-Ion), Nickel Cadmium (Ni-Cd) and alkaline batteries we were usually caught up with the issue of identifying the used up ones and those which still hold some charge whenever we have mixed up our batteries (which the manufacturer strongly suggests we must not do). We may try to isolate the usable from the used ones visually or by pure luck but that means disposing the usable ones if we do it by mistake. If we try to secure a workable battery tester the kind electricians use we maybe require to spend more and the whole unit could be a little bit bulky by today's standards where almost all gadgets are sold in shrunken size to get by with the trend. As the saying goes, if there's a need, there's a way and probably it was the reason why when we patiently seek something we need, the right equipment comes along and it may not even cost a lot to be brought home. The only question is would you buy it?
Draper is a UK based company and had been a trusted brand in tools with history dating back since 1919. Aside from mechanical, automotive and carpentry tools however, their product range includes electronic devices like LED flashlights and measuring gadgets which are truly useful to all hobbyists and average individual. The author's recent acquisition was something unintended but turned out to be a wise choice while shopping for some basic needs that ended up on a Robert Dyas store. The catch, a Draper 72090 dry cell battery tester was paid for only GBP 4.50 but the benefits had been truly appreciated. If you are using batteries ranging from a wall clock, a shaver, remote controls, digital cameras and so on, you may easily discard the batteries once you realize they are not providing enough power on the device they were intended to power up but if you take some point for consideration, the battery cells aren't completely empty. While alkaline batteries on digital cameras may seem empty to meet the power requirement for the unit, there is still something left that will make it usable to power a wall clock for a number of days and so on. You only need a battery tester to test the batteries and allocate them to be utilized on devices where the minimal power remaining could still sustain to operate them thus saving you extra money to buy more batteries. The AA sized batteries are the ones with a variety of uses and will benefit much from the applications of a battery tester. Measuring a bit smaller than a typical steel tape measure, the Draper 72090 battery tester has a movable "L shaped" probe that could be pulled out from the the main body with metal ends that could be brought in contact with a battery's positive (+) and negative (-) poles in order for the test to be made. A small window on the tester's body allows a measuring hand to be visible indicating that the battery needs to be replaced or recharge when it points within the red line and that it could still be of use when pointing within the green line.
