TTi Techtronic Industries is actively promoting the widespread use of 21700 tabless/full tab batteries in the power tool industry. As early as last August's Miwaukee Pipeline event, its professional brand Milwaukee took the lead in launching the MX FUEL FORGE XC8.0 and FORGE HD12.0 lithium batteries equipped with 21700 tabless technology. At the end of January this year, its consumer brand RYOBI followed suit and released a new Edge series of lithium batteries using the same technology (click to jump to view details). Now, RIDGID, another professional brand operated by TTi, has also officially announced the launch of the 18V MaxOutput EXP 4Ah lithium battery equipped with 21700 tabless battery cells, further consolidating the company's leading position in this field. Power Tools Eye-Opening Today, let's take a look at this new battery from RIDGID.
Regarding the tab-free (full tab) design of the battery cell, we have elaborated on it in the tweet introducing the first tab-free lithium battery in the power tool industry launched by BOSCH (click to jump to view details). Here is a brief review. The cylindrical battery is made of a long "thin film battery" wound and then wrapped in a metal battery shell. In the traditional design, the positive and negative electrodes are connected to the battery shell at both ends of the film, which is called the "tab". Due to the long electron flow path, the internal resistance increases, the efficiency is low and it is easy to heat up, which affects the battery life and safety. The tab-free/full tab design cancels the tabs at both ends of the film, directly cuts multiple small openings on the edge of the film, folds inward in the same direction when curling and packaging, and is connected to the battery shell as positive and negative electrodes through laser welding. In this way, the flow direction of electrons in the film changes from horizontal to vertical, the path is shorter, and there are fewer obstacles, which greatly improves the efficiency of electron flow.
RISGID claims that the latest 18V MaxOutput EXP 4Ah lithium battery "provides 3 times the energy in a compact body." The product uses 5 21700 tab-free cells, and the cell connector uses advanced laser welding technology. The heat dissipation system is also carefully designed, making the battery small in size, large in capacity, fast in charging, and long in life. In order to more intuitively demonstrate its excellent performance, RIDGID also provides actual comparative test information of this latest lithium battery and existing lithium batteries, further demonstrating its strong competitiveness.
The time taken for the 7-1/4-inch brushless circular saw (R8658) to cut 3 3/4-inch thick OSB boards is 22 seconds for the 4Ah standard lithium battery; 18 seconds for the 4Ah MAX OUTPUT lithium battery; 15 seconds for the 8Ah MAX OUTPUT EXP lithium battery; and 11 seconds for the latest 4Ah MAX OUTPUT EXP lithium battery!The cutting speed of the latest 4Ah MAX OUTPUT EXP lithium battery is 1 times faster than that of the standard 4Ah lithium battery! It is even 4 seconds faster than the 8Ah MAX OUTPUT EXP lithium battery!

Brushless 1/2-inch hammer drill (R861152) drills 2X8” yellow pine and drills 3 holes (2-9/16” self-feed drill bit, high-speed mode of the host) The time taken to complete the drilling is,    4Ah standard lithium battery: 23 seconds; 4Ah MAX OUTPUT lithium battery: 15 seconds; 8Ah MAX OUTPUT EXP lithium battery: 13 seconds; the latest 4Ah MAX OUTPUT EXP lithium battery: 10 seconds! In this test, the battery's limit can be squeezed out. The latest 4Ah MAX OUTPUT EXP lithium battery beats all other lithium batteries!

Brushless reciprocating saw cutting 2X10 yellow pine board (lifting weight 10 pounds)   The time taken to complete the cutting is 24 seconds for 4Ah standard lithium battery; 21 seconds for 4Ah MAX OUTPUT lithium battery; 18 seconds for 8Ah MAX OUTPUT EXP lithium battery; 14 seconds for the latest 4Ah MAX OUTPUT EXP lithium battery!The cutting speed of the latest 4Ah MAX OUTPUT EXP lithium battery is 71% higher than that of the standard 4Ah lithium battery! It is even 4 seconds faster than the 8Ah MAX OUTPUT EXP lithium battery!
Through the comparative test, it can be seen that the 18V MaxOutput EXP 4Ah lithium battery of RIDGID equipped with 21700 non-polar ear battery is indeed "small in size and big in energy". The host with this battery will greatly improve the user experience.

As for the size, it can be seen from the comparison of the pictures that in terms of thickness, it is comparable to the compact 5-cell 2Ah battery, and in terms of length and width, it is similar to the 8Ah and 12Ah batteries.This latest 4Ah lithium battery is expected to be officially launched in September 2024, and the price is to be determined.Power Tool Eye-opener Analysis believes that given the convenience brought by the sharing of R&D technology, TTi Techtronic Industries is very likely to upgrade its AEG and HART brand lithium batteries to advanced 21700 stepless ear batteries. The move is aimed at consolidating and expanding the group's leading position in the power tool industry to cope with market competition and changing user needs. In particular, in 2024, the group needs to achieve a higher growth target based on the revenue of US$13.7 billion in 2023 (click to view details), so technology upgrades and product innovations are particularly important. What do you think? The next question is when will TTi transfer the soft-pack batteries that Milwaukee has adopted to other brands under its umbrella?
