Do not tuck your pant legs into your boots because spilled acid can form a pool in your boots. Wear acid-resistant equipment such as gauntlet style gloves, an apron, and boots. To avoid splashing acid in your face, wear personal protective equipment (PPE) such as chemical splash goggles and a face shield. Consult the vehicle and battery owners’ manuals for specific instructions on battery handling and hazard identification. Workers that operate, maintain, and recharge batteries should use caution.īefore working with a battery, you should have training in proper handling procedures. Because batteries contain chemicals, chemical reaction by-products, and an electrical current they can pose a hazard to workers if not handled properly. Most batteries contain sulfuric acid and lead. There are different types of batteries such as lead-acid batteries, gel cells, and lead-calcium batteries. This doesn’t mean that you can’t leave your laptop plugged in while in the midst of a marathon work session, but you don’t need to leave it plugged in all day, every day.Batteries are used to power our automobiles, trucks, tractors, and construction or power equipment. It isn’t good for the battery, it introduces additional heat, and your batteries are happiest when they aren’t too hot and aren’t too full. You don’t need to constantly charge your battery. Not only will replacing the battery give you that nice multi-hour battery life back but it will ensure that you’re not using a battery on the verge of failure. If you used to get 5 hours off your laptop battery and now you get 30 minutes, that’s a good sign that the components of the battery are degrading. If you notice that your battery is no longer holding a solid charge, then you should consider replacing it. Quality parts and safety certifications cost money and what you save on the charger you could lose on a damaged laptop and battery (at best) or in a fire (at worst). If the official battery charger for your laptop costs $65 and the generic knock-off charger you found on eBay costs $9, you might want to reconsider. Overcharging is a serious threat to the health of your batteries. If your device is user-serviceable and you can easily open the case or a service panel to remove the battery, then doing so is in your best interest: it will prevent the expanding battery from (further) damaging your device and it will prevent any sharp edges inside the battery compartment from piercing the protective layer around the battery. If you puncture the swollen battery, you’re in for a bad time as the compounds inside will react with the oxygen and moisture in the air. When it comes to removing the battery, there is one very important rule: don’t further compound the problem by compressing, distressing, or compromising the outer casing of the battery. Charging a swollen battery is literally asking for it to turn into an exploding ball of noxious flammable gas right in your living room. Once the battery has reached such a point of failure that the battery is swollen, you must assume that all safety mechanisms in the battery are offline. Turn the power off, and above all else, do not charge the device. Once you notice the battery is swollen or compromised in any way, you should immediately stop using the device. Lithium is more reactive than previously used compounds, the batteries have very small partitions between the cells and the outer covering, and the entire battery is pressurized. Compared to its predecessors, the lithium-ion battery is less stable. Unfortunately there’s no such thing as a free lunch, so to speak, and all that high-density energy goodness comes with a trade off. They have high energy density, low self-discharge, and a very tiny memory effect: all features that make them perfect for inclusion is everything from MacBooks to Kindles. As far as compact batteries go, they’re pretty great. The vast majority of modern portable electronics, including laptops, smartphones, tablets, ebook readers, and fitness trackers are all powered by lithium-ion batteries. If you open up your phone to find a battery swollen to twice its size, proper care and handling is critical for both your safety and the safety of others. When a lithium ion battery fails, things can go south very quickly.
