6 Tips to Maintain Your Lithium-Ion Battery Pack |
Nowadays, lithium batteriesare 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 batteriesand 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.

Concrete Maintenance |
Proper concrete maintenance is key for preventing costly repairs. When a concrete slab needs to be replaced, the old material needs to pulled out before placing the new slab. This can get very expensive as most concrete is a minimum of three and a half inches thick, which makes the material very heavy. So in order to ease removal, the slab needs to be saw cut or jack hammered to break it up into smaller pieces. Once the slab is removed, the new stone base can be prepped. Typically, a concrete slab will cost at least six dollars per square foot to replace. So regular concrete maintenance is key.
So what types of maintenance are necessary to keep your concrete in good working order? First, make sure all cracks are sealed on a regular basis. Spring is a good time to go through all of your exterior concrete slabs and check for gaps and cracks. You don't want water to get down through the cracks and wash out the stone base below. This can create settlement which ultimately leads to cracking and trip hazards. A high quality concrete caulk is necessary to seal the joints up. Check with your local concrete supplier for material recommendations.
Cleaning is another concrete maintenance item. Regularly cleaning your concrete surfaces will keep carbon dioxide, acids, and chlorides from entering the concrete surface. Dirt, salt water, automobile fluids, deicers and sand are filled with these corrosive chemicals that can deteriorate the concrete surface. By keeping the surface free of these items, you will help prevent surface spalling. When it comes to cleaning your concrete, make sure you wait until the surface is at a cool temperature. You don't want to put really cold water on a hot concrete slab as it can put stresses on the material that can lead to cracking.
Sealing your exterior slabs is another high priority concrete maintenance item. One of the best ways to protect the surface of your exterior concrete is to limit the amount of water that transports harmful chemicals into the concrete's pores. Check with your local concrete supplier for some really high quality sealers. The best sealers penetrate the material to provide long-lasting protection. Most of these can be applied with either a plant sprayer or simple paint roller.
These are some of the most important concrete maintenance items for homeowners. But in addition to maintenance, it's important the concrete is installed properly from the beginning. Here are some general contractor tips for getting a quality concrete job.
1.Provide a four inch compacted stone base directly under the slab
2.Add control joints to control the cracking in the surface
3.Air Entrained Concrete - Make sure the proper concrete mixture is used for the local climate. 4.Not all concrete will stand up to freeze thaw cycles.
5.Water - Make sure your contractor doesn't add water to the concrete truck on site as this will weaken the material
6.Cure - Be sure to include a curing compound or keep the surface of the material wet during the first few days after pouring.
Proper concrete maintenance and installation will help you prevent costly repairs down the road.

How to Install Concrete Pump Pipes |
The construction industry is one of the main fast-moving industries, and a concrete pump proves a valuable tool for a project. A concrete pump uses to transfer liquid concrete with the help of a pump. Boom concrete pump and line pump are the two most commonly used types of concrete pumps.
Concrete is a very abrasive material, and proper installation is vital for good pipe performance. The concrete pump uses widely in commercial and residential construction projects, and the concrete pump is the best technique for placing and pouring the concert. Due to the heaviness of the concrete pump, it is essential to handle it carefully during installation. Four principal zones of pipe that are essentially critical for the system of pipe soil are:
Installation of concrete pipe can affect the pipe's performance and can reflect techniques of modern construction. The procedures and methods of installation should be designed to improve the performance of the pipe. A wide range of backfill material may use to provide the pipe installation. A sound installation can offer the contractor, engineers, and owners versatility and meet their requirements.
For the installation of concrete pump pipes, you need two persons who can handle this procedure.
● The soil area provides significant support to the pump pipe and can also reduce pipe stress.
● Uncompact and loose placed bedding under the pipe invert is one main factor in reducing the pipe's stress.
● The material used for the construction can affect the structural requirements of the pipe. Soil may prove challenging to compact in the bedding portion and haunch area.
● By using a backhoe or a crane, the large pipe can be lowered into the trench. Workers can set the smaller pipe by hand and can adjust thepipe section to the proper place.
● The end of the small plug of the new pipe can insert into the bell of the pipe. It should insert at the end of the installed pipeline.
● Now you can push a new section into place using pipe pullers or any other tools.
● The concrete pump has a bell gasket stretched. It uses a rounding device that ensures everything is in its proper place when it passes several times with the gasket's circumference.
● Grade and line established for the culvert and sewer construction. Helium-neon laser is available for culvert and sewer construction.
● A worker with any rod can measure offset for construction accurately.
● The helium-neon laser with low power is not a dangerous instrument, but constantly looking at the 1 to 3 milliwatt laser may prove damaging for the eyesight, so you should avoid it.
● When installing a pipe with the tunneling method or jacking for the construction, it is necessary to establish an accurate control point at the bottom of the work shaft or the bottom of the jacking pit.
● For large pipe size and slope trench wall, wide trenches can use. A Batter board will not be enough for this purpose.
These are some steps for installing concrete pump pipes, and better performance depends on the proper installation of concrete pump pipes.
