I've gave up on batteries about a decade ago. All my tools run on AC, gasoline, premix, or elbow grease.
Therein lies the problem... a decade ago, the top of the line battery operated tools were still NiMh, and the rest were still NiCd holdovers.
It wasn't until 2005 that Milwaukee introduced the innovative but ultimately ill fated 28Volt battery platform in the USA. The innovation was Milwaukee's bet on lithium ion battery technology. Prior to 2005, no common commercially available battery operated tool dared to use LiIon battery chemistry, as it was thought to be unsuitable for tools. During the same year (2005), Metabo, in conjunction with the Cordless Alliance System, a consortium of mostly European tool companies who have standardized on a common battery platform, tentatively introduced LiIon cells in some tool batteries.
Milwaukee's 28v system didn't gain much traction, but the benefits of Lithium Ion (no memory effect, significantly lighter weight, significantly higher energy density per unit of mass, significantly slower self discharge, and other benefits...) took the industry by storm. By 2009, exactly 10 years ago, both Makita and Hitachi reached negotiated settlements with Milwaukee, who had sued almost every tool company in the industry for patent infringement (in the US market)... because everyone was now migrating to the clearly superior lithium ion batteries. It was a game changer.
If you left the game 10 years ago, you're missing the best innings. You're missing out on the field goals... which is the freedom from cords and gas fumes.
I too, had given up on cordless. Thirty years ago, I had a full kit of 9.6v battery operated tools, that were neat and convenient for little things, but ultimately relegated to the status of toys, not tools. When the 12v versions of the same tools came out, I didn't bite. Likewise, I ignored the 14.4v and 18v reincarnations that occurred over the years. I was finally intrigued by Milwaukee's 28v line, but stayed away.
About five years ago, a neighbor gave me a 20v lithium ion impact driver, with a battery, that he had no charger for. He buys the contents of abandoned storage units, and this tool came with the lot. I thanked him and put it away, and forgot about it. Over a year went by, and I stumbled across the tool by accident, and pulled the trigger. Not only did it still work, it worked stronger than my NiCd tools ever did even when they were new and fresh off the charger. And here this LiIon tool had been sitting forgotten in a drawer for over a year, and who knows how long it had been since it was charged prior to my neighbor giving it to me, because he didn't have a charger, and who ever had the storage unit had abandoned the contents for at least several months prior to the contents being auctioned off.
I was sold. I bought a charger, and the rest of the tools I that I use frequently... and let me tell you... the freedom from cords adds so much to the efficiency, utility, and safety of using the tools. It would be silly to deny yourself these incredible benefits, based on your memories of older NiMh and NiCd battery tools from over a decade ago. Times and technology have changed significantly since then.
