Lithium Ion (Li-Ion) battery technology is one of the fastest growing trends in the tool community, and certainly for good reason. Lithium Ion batteries have the best energy to weight ratio, meaning they pack the most power with the smallest amount of bulk. They also experience no memory effect or, lazy battery effect. This occurs when a battery can no longer accept a maximum charge for having been repeatedly recharged without being fully used (a common symptom of Nickel Cadmium (NiCad) batteries). Li-Ion batteries, conversely, have absolutely no memory and can continually accept a maximum charge. Additionally, Lithium Ion batteries have a very slow rate of charge loss while the battery is disengaged. What is the difference between Lithium Batteries and Lithium Ion Batteries? The difference is in the chemistry; a Lithium battery is a disposable power source composed of lithium metal compounds - the key word, here, being disposable; Lithium batteries can not be recharged. Lithium Ion batteries, on the other hand, are intercalated, meaning the lithium ion inside the battery moves between two internal electrodes. This movement, or reversibility of the lithium ion accounts for the battery's rechargeability. What are the benefits of Lithium Ion Technology? -- Lithium Ion batteries hold a lot of power and are surprisingly light-weight, especially with consideration to other rechargeable batteries. -- Li-Ion batteries combine single cell technology with a greater energy reservoir than Nickel Metal Hydride and Nickel Cadmium batteries. They store more power for their size than both NiCad and NiMH. -- Li-Ion batteries hold their charge for significantly longer than other comparable batteries, and provide steady power until that charge is completely gone. Other batteries gradually and consistently loose power as you work. Li-Ion batteries stay strong until the last push. Are there disadvantages to using Lithium Ion Batteries? The disadvantages with using Li-Ion battery technology are generally few and far between, and technological advancements are making them even less so. Manufacturers have recently improved the Lithium Ion recipe to reveal a more reliable battery. Still, every giant has its weaknesses: -- Li-Ion batteries are sensitive to intense hot and cold temperatures. In extreme temperature conditions, the battery will degrade more quickly. -- Li-Ion batteries degrade regardless frequency of use. -- The Li-Ion battery's built-in computer chip tells the battery to refuse a charge once the batteries power falls below a certain point. If this occurs, the battery is beyond repair. Although these defects are more applicable to the older Lithium Ion batteries, the possibility of seeing these problems is still worth noting. Fortunately, these said defects are fairly rare, and easily avoided. -- Store Li-Ion batteries (and other batteries as well) in a cool, dry place. -- Use your Li-Ion batteries often. -- Be certain Li-Ion batteries have a full charge before storing them, and pull them out every so often to use and recharge. Watch the batteries power level to be sure it doesn't fall below the charge limit. General Li-Ion Battery Tips: -- On occasion Lithium Ion batteries require more than one charge (sometimes 2 to even 10) to accept a full charge. The first time you charge your battery, leave it to charge over night. This ensures you'll have maximum power for your first use. -- To maintain proper balance in your battery, leave it charge over night about once per week for the life of the battery. -- When buying a new Lithium Ion battery, make certain you are buying a fresh one. There's a chance a battery has been degrading on the shelfs of manufacturer's and distributor's so be certain you are buying a new one. Most manufacturers provide a date code on the battery or packaging. Check dates before you purchase, and be confident you are getting a fresh, high-performance battery. https://telegra.ph/6-Tips-to-Maintain-Your-Lithium-Ion-Battery-Pack-10-24 https://sylpheed.sraoss.jp/redmine/boards/1/topics/4561 https://educatorpages.com/site/junhuamachinery/pages/the-cement-mixers-with-high-standards https://www.exoltech.net/blogs/post/12142 https://www.castingcall.club/m/junhuamachinery https://www.writeurl.com/publish/xe9omtwqnzi0nh9qxpqi

This tool is additionally recognized as a concrete mixer. The core task of a concrete aggregator or concrete mixer is to make a homogeneous aggregated mixture of crushed rock or sand, water to make solid and also long-lasting concrete. The configuration of an average concrete mixer is nearly the exact same. A concrete mixer contains a revolving drum as a basic part. This revolving drum is the place where the process of mixing takes place and the concrete forms consequently. When the concrete is needed in large amounts a much-advanced variation of this mixer is needed. For little volumes of concrete, many compact concrete mixers are made use of by the fabricators. A much standard alternative to the cement mixer device is mixing the concrete by hand. This procedure is implemented in a wheelbarrow. There are different firms that sell changed versions of concrete mixers as well as wheelbarrows and also tarpaulins for the purpose of concrete blending. Initially, the cement mixer is the exceptional invention of Columbian Industrialist Gephardt Jaeger. The construction market requires heavily industrial concrete mixers. These are also very useful when the workers and industrialists require the ready-mix concrete or the pre-stressed or pre-cast-concrete concrete. The innovation of the industrial concrete mixers has actually improved and revolutionized cement manufacturing. Different kinds of fixed mixers have been in the marketplace location. Each sort of mixer has its own distinct functionality as well as internal stamina. They target individually various aspects of the market with regards to the cement need rate. The most frequently utilized cement mixers are of 3 wide kinds. The twin-shaft mixer, vertical axis mixers (likewise called Planetary and Pan Mixers), and also the Drum mixers (likewise called as Tilting Drum and Reversing Drum). The twin shaft concrete mixers are recognized for their innovative top-quality concrete mixing in a substantially brief span of time. These are utilized for strong concrete manufacturing. Normally the kind RCC and also SCC in batched of 2-6 cubic meters is produced. The upright axis concrete mixer is generally used for pre-cast concrete manufacturing. While the drum mixer is utilized for the production of a big amount of concrete (ordinary batch sizes of 3-9 cubic meters). These cement mixer selections have actually offered diversity to the job as well as usability of concrete/cement by the building sector. The cement combination is now produced with premium quality in less time according to the distinct needs of the employees and/or builders. The core job of a cement collector or concrete mixer is to make a homogeneous aggregated blend of gravel or sand, water to make the solid as well as long-lasting concrete. For tiny volumes of concrete, many compact concrete mixers are used by contractors. These are likewise really useful when the workers and also manufacturers demand the ready-mix concrete or the pre-cast-concrete or pre-stressed concrete. The twin shaft concrete mixers are recognized for their advanced quality concrete mixing in a considerably brief period of time. The vertical axis concrete mixer is generally made use of for pre-cast concrete manufacturing.

Nowadays, lithium batteries are found in a lot of devices, such as digital cameras, laptops, mobile phones and a lot of other electronic devices. If you want to maintain your battery pack and extend its life, we suggest that you follow the tips given below. These tips will also protect your smartphone and other devices from damage. Read on. Charge your batteries first Once you buy a battery pack, make sure you charge it for 12 hours before putting it in your device. As a matter of fact, all manufacturers recommend charging these batteries for at least 12 hours before first use. Actually, if you have a lithium ion battery, this approach is very important. Unlike the regular Ni-MH Ni-CD batteries, lithium-ion batteries are pre-activated. Since they have a low self-discharge rate, make sure you charge your batteries first. As soon as the charger gives you the indicator, you can remove the batteries and put them in your device. Here, it's also important to note that these batteries need to go through at least 3 cycles before reaching their full capacity. Use the right charger All of us take good care of our electronic gadgets but we tend to ignore the outcomes of using the wrong charger. When you buy a charger, make sure you opt for the original charger. If you can't get the original one, we suggest that you choose a high-quality charger with overcharge protection. Buying a low-quality unit is not a good idea as it may result in shorter run time, battery failure or fire/explosion. Don't overcharge Typically, low-quality chargers end up overcharging the battery. What happens is that the substance inside the battery heats up, which may reduce the lifespan of the battery. Therefore, it's better that you fully charge your battery. In some cases, overcharging may cause the battery to explode. Don't touch the metal contacts For highest performance, make sure you clean the battery contacts on a regular basis. When you carry the batteries with you, you might want to prevent the contacts from touching metal stuff like your car keys. This is important if you don't want to face a short circuit. If this happens, you may end up damaging your battery. In a worse scenario, fire or explosion can also occur. Don't use the battery in extreme temperatures Usually, lithium-ion batteries can work well only if the temperatures are in a certain range. If used in extreme temperatures for a long time, the backup time and useful cycles will decrease. Don't store your battery without charging If you leave your battery without charging for more than 3 months, you may cause damage to it. Ideally, in this situation, make sure you partially charge your battery pack before putting it in your drawer for a few months. Ideally, it should be charged at least 30% of capacity. Long story short, if you are going to buy a lithium-ion battery pack, make sure you follow these tips. By following these tips, you can extend the lifespan of your battery.
