Top 5 Tips to Maintaining EV Battery Life
Electric vehicles are a joy to own but this new technology using advanced Lithium-ion battery packs requires a different type of maintenance than your traditional gasoline engine.
We countdown the top 5 maintenance steps that can be taken to extend the life of your EV battery.
5. Don’t leave your battery sit at a 100% state of charge
Most EVs have an option for a “Standard” charge or a “Range” or “Max” charge. By all means, do the maximum charge when you need it, but do it right before you start using the battery for the trip. Most EVs have charge timers to help you plan for this. If your EV doesn’t have that, do an overnight standard charge and then charge the last 10-20% in the AM before departure. Leaving a battery pack at max charge for even relatively short periods of time can possibly affect its life. As a rule of thumb, try to never let your battery sit at maximum state of charge for longer than 8 hours.
While you may be able to time your max charge and departure times well, daily charging to 100% is stressful to your battery. This is why most vendors offer “standard” or “normal” charge levels which wont help you achieve the maximum EPA range rated for your vehicle. If you don’t need the max charge, then don’t use it. Generally lithium-ion batteries do best when they operate in the 30% to 90% range for state of charge. Although a bit extreme, prolonging the time spent above or below that range theoretically may lead to a shorter pack life
Tesla Model S TIP: For overnight charging that requires a 100% MAX charge (ie prior to a Tesla road trip), set your “start charge time” to a time that will result in a full charge roughly 60 minutes before your departure.
4. Avoid deep discharging of the battery pack
Conversely, leaving your battery in a discharged state for an extended period may also impact its life. Most vendors protect batteries from becoming completely discharged as that can effectively “brick” the battery and leave it completely useless. The general rule of thumb is to plug in and charge whenever you can. That doesn’t mean going out of your way for a few kW of charge, but it does mean plugging your car in nightly and maintaining a reasonable charge level. What is a low state of charge? Under 30% charge is generally considered low and thus you should not let your EV sit at that low state of charge for an extended period.

Also beware that EVs consume power even when not being driven. With the Model S, it loses about 1% of its charge per day.
3. Be mindful of extreme temperature conditions
This is less applicable to the Tesla Model S which has its own built in thermal management system that pre-conditions the battery (ie. warms the pack when too cold and vice versa), but the general rule of thumb for batteries of Lithium-ion composition is to keep the battery pack between 20F – 85F.
Heat is the enemy of Lithium-ion and may increase battery degradation when consistently exposed to high temperatures. This phenomenon was enough to motivate Nissan to produce a “hot climate battery” for their LEAF after owners within hotter climates complained of battery loss.
Conversely, extreme cold weather can impact performance for a battery of lithium-ion chemistry while lowering the discharge capacity.
2. Plan ahead for extended storage
If you’re going away on vacation or for a business trip the best thing for your car is to set the charge level to 50% and leave it plugged in. If you’re leaving your EV at the airport or somewhere where you can’t leave it plugged in beware that you’re going to lose some charge per day. Charge to a level where you can get to the airport, let it sit for the trip and then still have enough charge with buffer to get home. Don’t let it sit unplugged at an airport for days on end at a 90% charge state if possible. Still, leaving it at 90% is better for the battery (and you) than leaving it at 10% and coming back to find the battery completely discharged.
1. Periodically fully charge and “balance” your battery
Lithium-ion batteries are designed to minimize the “memory” issues often found in older battery technologies, however the battery packs in EVs are more complex and often comprised of multiple individual batteries packed together into removable modules. There’s as many as 7,000 individual cells in the Model S.
Battery balancing is about maximizing your battery’s capacity and evening out the charge distribution. Modern EV battery packs include an automatic battery balancing component, but there’s steps that you can take to help the process along.
While you may never need the maximum range that your battery can provide and you may never take long trips, a periodic range or max charge is helpful to your battery’s management system. I’d suggest doing this about once every 3 months or so and keep in mind that after you fully charge you should not let it sit, that would be a violation of battery management rule #5.
Disclaimer: We’re dealing with expensive components. Read the manual for your EV, search your EV forums, develop your own rules, be consistent, but adjust as needed. The rules above are general rules for any EV that may help extend the life and health of your battery. Your own mileage (range!) may vary.

Tesla Optimus Gen 3 is coming to the Tesla Diner with new ambitions
Tesla’s Optimus robot left the Hollywood Diner within months of opening. Now Musk is planning its return with a bigger role and a major Gen 3 upgrade underway.
Tesla’s Optimus robot was one of the most talked-about features when the Tesla Diner opened on Santa Monica Boulevard in Hollywood on July 21, 2025. Dubbed “Poptimus” by Tesla fans, the Gen 2 robot stood upstairs at the retro-futuristic, drive-in theater and Tesla Supercharging station, scooping popcorn into bags and handing them to guests with a wave.
The diner itself had been years in the making. Elon Musk first floated the idea in 2018 with a tweet about building an “old-school drive-in, roller skates & rock restaurant” at a Hollywood Supercharger. What eventually opened was a unique two-story neon-lit space, with 80 EV charging stalls, and Optimus serving as a live demonstration of where Tesla’s ambitions were headed.
If our retro-futuristic diner turns out well, which I think it will, @Tesla will establish these in major cities around the world, as well as at Supercharger sites on long distance routes.

But Optimus did not stay long, and was gone by December 2025.
Now, the robot is set to return with a more demanding job. Musk has ambitions for Optimus to take on a food runner role in 2026, delivering meals directly to cars at the Supercharger stalls. While the latest Gen 3 Optimus is likely to initially take on its previous popcorn-serving role, it wouldn’t be out of the question for Optimus to see a quick promotion. With improved hand dexterity that features 50 total actuators and 22 degrees of freedom per hand, and significantly more powerful processing through Tesla’s latest AI5 chip that includes Grok-powered voice interaction, Musk described Optimus at the Abundance Summit on March 12, 2026, as “by far the most advanced robot in the world, Nothing’s even close.”

That confidence is backed by a major manufacturing shift. At the Q4 2025 earnings call in January, Musk announced Tesla would discontinue the Model S and Model X and convert those Fremont production lines to build Optimus. “It’s time to basically bring the Model S and X programs to an end,” he said, calling for a pivot that reflects where the Tesla’s future lies.

The Boring Company clears final Nashville hurdle: Music City loop is full speed ahead
The Boring Company has cleared its final Nashville hurdles, putting the Music City Loop on track for 2026.
The Boring Company has cleared one of its most significant regulatory milestones yet, securing a key easement from the Music City Center in Nashville just days ago, the latest in a series of approvals that have pushed the Music City Loop project firmly into construction reality.
On March 24, 2026, the Convention Center Authority voted to grant The Boring Company access to an easement along the west side of the Music City Center property, allowing tunneling beneath the privately owned venue. The move follows a unanimous 7-0 vote by the Metro Nashville Airport Authority on February 18, and a joint state and federal approval from the Tennessee Department of Transportation and the Federal Highway Administration on February 25. Together, these green lights have cleared the path for a roughly 10-mile underground tunnel connecting downtown Nashville to Nashville International Airport, with potential extensions into midtown along West End Avenue.
Music City Loop could highlight The Boring Company’s real disruption
Nashville was selected by The Boring Company largely because of its rapid population growth and the strain that growth has placed on surface infrastructure. Traffic has become a persistent problem for residents, convention visitors, and airport travelers alike. The Music City Loop promises an approximately 8-minute underground transit time between downtown and the Nashville International Airport (BNA), removing thousands of vehicles from surface roads daily while operating as a fully electric, zero-emissions system at no cost to taxpayers.
The project fits squarely within a broader vision Musk has championed for years. In responding to a breakdown of the Loop’s construction costs, Musk posted on X: “Tunnels are so underrated.” The comment reflected a longstanding belief that underground transit represents one of the most cost-effective and scalable infrastructure solutions available. The Boring Company has claimed it can build 13 miles of twin tunnels in Nashville for between $240 million and $300 million total, a fraction of what comparable projects cost elsewhere in the country.

The Las Vegas Loop, The Boring Company’s first operational system, has served as a proof of concept. During the CONEXPO trade show in March 2026, the Vegas Loop transported approximately 82,000 passengers over five days at the Las Vegas Convention Center, demonstrating the system’s capacity during large-scale events. Nashville draws millions of convention visitors and tourists each year, and local business leaders have pointed to that same capacity as a major draw for supporting the project.
The Music City Loop was first announced in July 2025. Construction began within hours of the February 25 state approval, with The Boring Company’s Prufrock tunneling machine already in the ground the same evening. The first operational segment is targeted for late 2026, with the full route expected to be complete by 2029. The project represents one of the largest privately funded infrastructure efforts currently underway in the United States.

Elon Musk’s $10 Trillion robot: Inside Tesla’s push to mass produce Optimus
Tesla’s surging Optimus job listings reveal a company sprinting from prototype to one million robot production.
Tesla is accelerating its push to bring the Optimus humanoid robot to high volume production, and its recent job listings tells the story as clearly as any earnings call.
With well over 100 Optimus related job openings now posted across its U.S. facilities, Tesla is signaling a critical pivot for the program, moving it from a captivating tech demo to a serious manufacturing endeavor. Roles span the full spectrum of the product lifecycle, from Robotics Software Engineers and Manufacturing Engineers to Mechanical Integration Engineers and AI Engineers focused on world modeling and video generation. One active listing for a Software Engineer on the Optimus team asks candidates to build scalable and reliable data pipelines for Optimus manufacturing lines and develop automation tools that accelerate analysis and visualization for mass manufacturing.
Tesla is racing toward a one million unit annual production target. The clearest signal yet that Tesla is treating Optimus as its primary business came on January 28, 2026, during the company’s Q4 2025 earnings call. Musk announced that Tesla is ending production of the Model S and Model X, and will repurpose those lines at its Fremont, California factory to build Optimus humanoid robots.
A production intent prototype of Optimus Version 3 is planned to be ready in early 2026, after which Tesla intends to build a one million unit production line with a targeted production start by the end of 2026. To support that ramp, Tesla broke ground on a massive new Optimus manufacturing facility at Gigafactory Texas in late 2025, with ambitions to eventually reach 10 million units per year.
Tesla Giga Texas to feature massive Optimus V4 production line
The business case for scaling this aggressively is rooted in labor economics. Musk has stated that “Optimus has the potential to be the biggest product of all time,” reasoning that if Tesla can produce capable humanoid robots at scale and reasonable cost, every task currently performed by human labor becomes a potential application. In a separate statement, Musk framed Optimus’s long term importance even more bluntly, saying it could surpass Tesla’s vehicle business in scale with the potential to generate $10 trillion in revenue.
The industries Tesla is targeting first are those most burdened by repetitive physical labor. Early applications include manufacturing assembly, material handling and quality inspection, as well as logistics tasks like loading, unloading, sorting, and transporting goods in warehouses and distribution centers. Longer term, Tesla’s vision is for Optimus to penetrate household, medical, and logistics scenarios at the scale of a smartphone rollout.
