I've mislaid count of really galore times I've seen personification propulsion distant bully batteries. Man, those things costs money, and it's truthful wasteful. But it seems to beryllium nan first point group do erstwhile thing isn't working.

Also: The champion rechargeable batteries you tin buy

Before I flip a artillery into nan recycling, I ever trial it. I mostly usage a multimeter, but that involves knowing what nan voltages of a artillery are erstwhile they're afloat and dead, truthful unless you person a encephalon that remembers worldly for illustration that complete people's birthdays, this isn't a applicable method.

But fearfulness not, because I've recovered a really cool artillery tester that's easy to use, accurate, and tin beryllium utilized pinch virtually immoderate artillery you'll find astir nan location -- some one-use and rechargeable.

And erstwhile I opportunity beautiful overmuch immoderate battery, I mean conscionable that. The Dlyfull B4 artillery tester useful pinch 1.2V Ni-MH, 1.45V zinc air, 1.5V alkaline, 3.0V lithium manganese, 3.2V LiFePO4, 3.7V Li-ion, and 6.0V, 9.0V, and 12.0V Alkaline packs. It is compatible pinch AAA, AA, C, SC, D, N and PP3 sizes, arsenic good arsenic a full scope of fastener cells, including CR123A, CR-V3, 2CR5, 23A, and 27A.

The Dlyfull B4 tin trial a batch of different times of battereis.

The instrumentality itself needs 2 alkaline AAA batteries to activity -- and a group are provided to get you going.

Once you've figured retired wherever your artillery goes, push nan affirmative extremity into nan slot and usage nan probe to touch nan different extremity (button cells slot into nan tester successful specified a measurement that you don't request nan probe), and nan LCD surface will show you nan voltage, remaining capacity, and a level barroom display.

It's truthful elemental that I tin do it single-handed and return a photo. I utilized this nan different time to spell done a heap of batteries near for recycling astatine a store, and retired of nan 50 aliases truthful batteries left, much than half were little than 50% discharged, and had plentifulness of life left.

You tin besides usage this to trial to spot if rechargeable batteries are astatine nan extremity of their lives. Fully complaint 1 and spot what it says connected nan metre -- if it shows little than 80% charge, nan rechargeable artillery is astatine nan extremity of its life and needs replacing.
