The Tesla ownership experience is intended to be as convenient as possible, with the vehicles themselves needing very little maintenance and practices like charging being effortless with the Supercharger Network’s plug-and-play nature. Yet even amidst all these conveniences, Tesla owners have cited a notable pain point in their ownership experience: their cars’ 12V battery.

RELATED: Tesla 12V Lithium-Ion battery replacement (up to 70% lighter, 4x life)

Similar to traditional vehicles, Teslas utilize a conventional 12V battery to power components like emergency blinkers, airbags, seatbelt pre-tensioners, and the infotainment system. Typical 12V batteries last about 3-4 years under normal use in a fossil fuel-powered vehicle, but among Tesla owners, especially those who drive frequently, the lifespan of 12V batteries have been reported to go down to as short as 1-2 years.

Adding to the inconvenience is the fact that Teslas currently do not have a feature that notifies owners about the health of their cars’ 12V batteries. Tesla owners have responded to this by requesting for an update that would allow them to view the current state of their vehicles’ 12V batteries. One such request was posted on Twitter recently, with Tesla enthusiast @TeslaVibes stating that such a feature needs to be implemented in a future update.

Interestingly enough, Elon Musk completely agreed with the Tesla enthusiast’s request. The Tesla CEO added that major software improvements are set to be released for vehicles’ 12V batteries, which should allow them to last longer. “Couldn’t agree more — major software improvements are already in place to extend its life & more coming,” Musk wrote.

Considering Musk’s post, it seems that an update that would include 12V battery health warnings is all but confirmed. Such a feature will likely be universally appreciated by Tesla owners, as it could address a particularly infuriating part of the electric car ownership experience. Such a feature, if any, would definitely reduce the instances of owners running into major inconveniences when their vehicles’ 12V battery dies.

Elon Musk’s Twitter post suggests that Tesla is well aware of the limitations that 12V batteries still bring to the EV ownership experience. With this in mind, it would not be surprising if the company comes up with a superior alternative for 12V batteries in the coming years. Tesla, after all, is known for its quick pace of innovation, and the 12V battery is certainly an area that is in great need of some innovation.

It should be noted that the earliest versions of the original Tesla Roadster did not use a traditional 12V battery. Instead, Tesla opted to utilize a portion of the vehicle’s main lithium-ion battery pack to supply 12V for the all-electric sports car’s accessories and lights. The system was quite novel, but the idea was later dropped in favor of a more traditional 12V battery. Conventional 12V batteries were initially used for the original Roadster 2.0, and in every vehicle that Tesla has released since.

Starlink wrapped up 2025 with impressive growth, adding more than 4.6 million new active customers and expanding service to 35 additional countries, territories, and markets. The company also completed deployment of its first-generation Direct to Cell constellation, launching over 650 satellites in just 18 months to enable cellular connectivity.

SpaceX highlighted Starlink’s impressive 2025 progress in an extensive report.

Key achievements from Starlink’s 2025 Progress

Starlink connected over 4.6 million new customers with high-speed internet while bringing service to 35 more regions worldwide in 2025. Starlink is now connecting 9.2 million people worldwide. The service achieved this just weeks after hitting its 8 million customer milestone.

Starlink is now available in 155 markets, including areas that are unreachable by traditional ISPs. As per SpaceX, Starlink has also provided over 21 million airline passengers and 20 million cruise passengers with reliable high-speed internet connectivity during their travels.

Starlink Direct to Cell

Starlink’s Direct to Cell constellation, more than 650 satellites strong, has already connected over 12 million people at least once, marking a breakthrough in global mobile coverage.
Starlink Direct to Cell is currently rolled out to 22 countries and 6 continents, with over 6 million monthly customers. Starlink Direct to Cell also has 27 MNO partners to date.

Tesla’s Giga Nevada has reached an impressive milestone, producing its 6 millionth drive unit as 2925 came to a close.

To celebrate the milestone, the Giga Nevada team gathered for a celebratory group photo. 

6 million drive units

The achievement was shared by the official Tesla Manufacturing account on social media platform X. “Congratulations to the Giga Nevada team for producing their 6 millionth Drive Unit!” Tesla wrote. 

The photo showed numerous factory workers assembled on the production floor, proudly holding golden balloons that spelled out “6000000″ in front of drive unit assembly stations. Elon Musk gave credit to the Giga Nevada team, writing, “Congrats on 6M drive units!” in a post on X.

Giga Nevada’s essential role

Giga Nevada produces drive units, battery packs, and energy products. The facility has been a cornerstone of Tesla’s scaling since opening, and it was the crucial facility that ultimately enabled Tesla to ramp the Model 3 and Model Y. Even today, it serves as Tesla’s core hub for battery and drivetrain components for vehicles that are produced in the United States.

Giga Nevada is expected to support Tesla’s ambitious 2026 targets, including the launch of vehicles like the Tesla Semi and the Cybercab. Tesla will have a very busy 2026, and based on Giga Nevada’s activities so far, it appears that the facility will be equally busy as well.

Tesla Supercharger network delivers record 6.7 TWh in 2025

The network now exceeds 75,000 stalls globally, and it supports even non-Tesla vehicles across several key markets.

Tesla’s Supercharger Network had its biggest year ever in 2025, delivering a record 6.7 TWh of electricity to vehicles worldwide. 

To celebrate its busy year, the official @TeslaCharging account shared an infographic showing the Supercharger Network’s growth from near-zero in 2012 to this year’s impressive milestone.

Record 6.7 TWh delivered in 2025

The bar chart shows steady Supercharger energy delivery increases since 2012. Based on the graphic, the Supercharger Network started small in the mid-2010s and accelerated sharply after 2019, when the Model 3 was going mainstream. 

Each year from 2020 onward showed significantly more energy delivery, with 2025’s four quarters combining for the highest total yet at 6.7 TWh.

This energy powered millions of charging sessions across Tesla’s growing fleet of vehicles worldwide. The network now exceeds 75,000 stalls globally, and it supports even non-Tesla vehicles across several key markets. This makes the Supercharger Network loved not just by Tesla owners but EV drivers as a whole.

Resilience after Supercharger team changes

2025’s record energy delivery comes despite earlier 2024 layoffs on the Supercharger team, which sparked concerns about the system’s expansion pace. Max de Zegher, Tesla Director of Charging North America, also highlighted that “Outside China, Superchargers delivered more energy than all other fast chargers combined.”

Longtime Tesla owner and FSD tester Whole Mars Catalog noted the achievement as proof of continued momentum post-layoffs. At the time of the Supercharger team’s layoffs in 2024, numerous critics were claiming that Elon Musk was halting the network’s expansion altogether, and that the team only remained because the adults in the room convinced the juvenile CEO to relent.

Such a scenario, at least based on the graphic posted by the Tesla Charging team on X, seems highly implausible.
