I've worked hard over the past few years to move away from disposable alkaline batteries and replace them with rechargeable equivalents. After all, there are some great brands of rechargeable AAA, AA, C, and D cell batteries available that will last you for years.

And I've found that the best way to take care of these batteries is to charge them using a decent charger. Too many chargers pile in the amps, which in turn bakes the battery and dramatically shortens its lifespan. There's a lot more to charging a battery than just pushing power into it as fast as possible.

If you're looking for a battery charger that does it all, the Xtar VX2 Pro is a great option to consider.

The VX2 Pro is a two-slot battery charger that can take a wide variety of cell types and sizes. You can pop in AA, AAA, C, D, 18650, 21700, and more, and the unit will automatically detect the battery's chemistry, offering a wide array of functions to help you get the most from your battery.
