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.

Elon Musk drops a surprise update on Boring Company’s next big dig
Musk says Boring Company could shrink the Austin to San Antonio drive to just minutes.
Elon Musk says The Boring Company is working on what he called “a simple, precursor Hyperloop” tunnel connecting Austin and San Antonio, targeting speeds above 200 mph and cutting a drive that can take up to two and a half hours down to a consistent under 30 minutes. Musk posted the idea on X Sunday, in a reply to a repost of an AI generated video imagining a science fiction future with human colonies on other worlds, which he shared with the line “This is the future we shall bring into being.”

The Boring Company’s own account picked up the idea in the same thread, adding a detail about how the trip would actually work: “Because Loop/Hyperloop is express (i.e. no intermediate stops), one could travel from an Austin parking lot to a favorite San Antonio restaurant in about 30 minutes. As long as they both have Loop stations.” That framing ties the proposed intercity link to the same station model the company already runs in Las Vegas, where riders enter the tunnel network through small, garage style stops rather than one central terminal.
This is not the company’s first run at the Austin to San Antonio corridor. Boring Company floated tunnels between the two cities as far back as 2021, and later competed for a separate San Antonio Loop project tied to the airport before that specific bid stalled. Pitches for tunnels in Chicago, Los Angeles, and a New York to Washington corridor have followed a similar pattern of big announcement without a shovel in the ground.
What is different this time is the balance sheet, especially since The Boring Company closed a 3 billion dollar funding round led by investors in the United Arab Emirates earlier this month at a valuation near 23 billion dollars, giving the tunneling company more capital to chase speculative projects than it had during its earlier Texas pitches. The company is also mid-build on two other intercity systems it has actually broken ground on, inc;luding a Nashville tunnel linking downtown to the airport, where a second boring machine finished commissioning in June, and its Las Vegas network, where the station count keeps climbing on paper faster than tunnels get dug.
That gap between announcement and execution is the reason to treat Sunday’s post as an opening bid rather than a project. A tunnel spanning roughly 80 miles between two metro areas, running at speeds Boring Company has not demonstrated over any real distance, would dwarf anything the company has built. For now, the Austin to San Antonio Hyperloop exists as a caption under an AI generated space video.

Tesla eyes supply partners for Optimus mass production
Tesla certified three Chinese suppliers for Optimus mass production, signaling its robot timeline is accelerating.
Tesla’s robotics team traveled to Ningbo, in China’s Zhejiang province, on September 16 and spent the following day auditing component suppliers for Optimus, according to a Bloomberg report cited by RobotAIGeek. The visit moved three manufacturers from provisional status to certified mass production partners: Tuopu Group, which handles actuators and chassis components, Ningbo Joyson Electronic, a sensor supplier, and Zhejiang Sanhua Intelligent Controls, which builds thermal management systems. All three already supply parts to Tesla’s electric vehicles, and the audit reportedly came with fresh orders that supply chain reports put at an initial batch of roughly 5,000 units.
Tuopu, Joyson, and Sanhua built their manufacturing base serving the automotive industry, where tolerances and volume requirements are already close to what a mass produced humanoid robot demands. Sanhua in particular has history here. Teslarati reported last October that the company had received a roughly $685 million order for linear actuators tied to Optimus, a volume industry watchers estimated could cover around 180,000 robots once production ramped.
Supply chain reports tied to this week’s audit put Tesla’s near term production goal at about 1,000 Optimus units a week by late September, rising to 2,000 to 2,500 units a week by the end of the year. That pace would put real weight behind the timeline Tesla has been building toward since May, when it wound down Model S and Model X production at Fremont to convert that floor space into a dedicated Optimus line targeting one million units annually. JPMorgan analysts who toured the factory in August confirmed the conversion took roughly four months, a pace Musk has called unprecedented for a facility that size.
New drone video shows Tesla’s Optimus Factory reaching a turning point
Fremont is only the first phase. A second, larger Optimus plant is rising at Gigafactory Texas, where drone footage shared by Joe Tegtmeyer last week showed the structural steel nearing completion on the north end of the building. Tesla has said that facility is meant to eventually support production of up to 10 million units a year, though volume output there is not expected before 2027.
Commercial sales of Optimus are still targeted for the second half of 2027, but production is expected to start well before then. JPMorgan analyst Rajat Gupta has said Tesla’s “Optimus Academy” program, which uses early units to collect real world training data inside Tesla’s own facilities, is expected to be running later this year. Bloomberg Intelligence analyst Ian Ma described the Ningbo audits as “a positive commercialization signal for China’s humanoid supply chain,” noting that sentiment could improve further if the visit leads to confirmed supplier nominations and larger orders. The Solactive China Humanoid Robotics Index rose about 1.4% on the news, though it remains down roughly 30% for the year.

Tesla primes Cybercabs for 4K streaming and high bandwidth gaming with Starlink integration
Tesla is now shipping Cybercabs from Giga Texas with Starlink hardware built in as standard.
Tesla’s Cybercabs are now leaving Gigafactory Texas with Starlink hardware on the rear hatch in significant numbers, according to drone footage captured Tuesday by longtime Austin drone observer Joe Tegtmeyer. Production at the factory ramped back up after the Labor Day weekend, and his flyover of the outbound lot showed rows of gold Cybercabs alongside Model Y Long Wheelbase units, many carrying the satellite module for the first time as standard equipment rather than a one off retrofit.
Giga Texas today is busy with production coming back up following the long weekend. Of interest today in the outbound lot is the appearance of hundreds of Mode; YL’s and many more Cybercabs and for the 1st time equipped with the Starlink module one the hatch in big numbers.

Tesla first showed Starlink built into an actual Cybercab on August 10, when the Robotaxi account posted images of a single gold unit with the antenna integrated into the roofline above the taillights and called it the first Cybercab with Starlink integration. That followed a July reveal where Tesla and Starlink jointly posted a cutaway diagram of the antenna placement without a working vehicle to back it up. Ashok Elluswamy, Tesla’s VP of AI software, said at the time that the connection isn’t required for the car to drive itself. It exists mainly for navigation, customer service and keeping tabs on the fleet.
Musk has made a different case in public. During Tesla’s Q2 earnings call, he said the company can’t afford robotaxis stranded in what he called “Bermuda Triangles of lack of cellular connectivity,” and he separately claimed on X that Starlink will eventually reach every Tesla built, calling it the only way to deliver high bandwidth to billions of vehicles. He has also pitched the antenna as an entertainment upgrade, telling riders they would be able to stream 4K video or play games during a trip.
The rollout has moved fast since. Robotaxi service opened to the public in Austin on September 3, and Cybercabs had already been spotted with Starlink hardware in Houston and near Miami International Airport in the weeks before Tuesday’s factory footage showed the module shipping at volume rather than on scattered test units. Whether the satellite link earns its keep is still an open question. Tesla’s unsupervised service currently runs in dense metro geofences in Texas and Florida, markets where cellular coverage is already strong, which is not where the rural dead zones Musk describes tend to show up.
