    This the inside of Ridgid's new 18-volt Hyper Lithium battery. The type of cells that were used determine the amp-hour rating - this is a 4.0 Ah pack. Among other things, the electronics provide short-circuit protection, over-discharge protection, and over-current protection. There is nothing unusual about the amount of electronics in this pack; nowadays, most packs contain some kind of circuit board. This one just happens to be big.

    These are both high capacity packs, but how do you tell their Ah rating? Well, you could...

    ... look on the other side where the rating might be printed, but that number is only shown on one of the batteries. The other way is to do some simple math based on the label...

    The one thing I remember from high school physics (maybe the only thing) is that Volts x Amps = Watts. That means Volts x Amp-hours - Watt-hours. The Watt-hour (Wh) ratings are printed on these packs so you can work backwards to the Ah ratings. The pack on the left is the older 3.0 Ah pack and the one on the right the newer 4.0 Ah pack

    This is the new compact Hyper Lithium battery. it has half the number of cells of the high capacity battery, which is why it's 2.0 rather than 4.0 Ah. Still, it's better than the older compact pack, which was 1.5 Ah. This size pack is what normally comes with Ridgid tools. There may be a few that come with the larger, high capacity pack, but usually they come bare or with compact packs.

    This should be familar to anyone who uses sub-compact tools. It's a compact (three-cell) 12-volt (10.8-volt nominal) pack. It's the newest model and if you look at the label you'll see that it's rated for 2.0 Ah.

    This is the high capacity 12V (10.8-volt nominal) pack. It contains six cells to the standard pack's three, which is why it is rated at 4.0 rather than 2.0 Ah.

If the core of any cordless system is the battery (and it is), then Ridgid's system just got better.

Ridgid recently upgraded the cell chemistry and electronics in the Hyper Lithium-Ion packs for their 12- and 18-volt tools. The new batteries are the same size and shape as previous models but the colors and graphics are slightly different.

Available in both 2.0 and 4.0 Ah sizes, the batteries are said by their maker to operate in extreme temperatures, from 29F (-20C) to 158F (70C). The improved electronics perform a number of functions, including providing protection against short-circuiting, over-discharge, over-current (too rapid draw that can overheat the pack). The company also released a new charger that it claims fills the 18-volt batteries 50% faster than earlier models.

The 18-volt batteries were released in July and the 12-volt batteries in August of 2013. All packs have a limited 3-year limited warranty. Prices are listed below.

18-volt 2.0 Ah: $79
18-volt 4.0 Ah: $119
12-volt 2.0 Ah: $49
12-volt 4.0 Ah: $89
