Tentang Batterai VRLA
Batterai SLA mempunyai 2 type yaitu batterai sell GEL dan AGM.
Gel Cells are batteries that use an electrolyte suspended in gel instead of liquid. They are used in applications that don’t require an initial high current surge. Instead of a quick surge of current, gel cell batteries deliver a steady supply of current over a longer period. Gel cells are sealed to prevent the release of dangerous gases and the gelled electrolyte guarantees that they will not leak if overturned. This makes them safe to use indoors and around children. The safety and electrical characteristics of gel cell batteries make them the battery of choice for use in applications such as computer backup power supplies and in children’s motorized vehicles.
AGM (Absorbed Glass Mat) batteries are sealed wet cell batteries that are quickly replacing gel cell and vented wet cell batteries. Because AGM batteries will not leak acid or release dangerous gases, they are the most appropriate battery for use in sporting vehicles like boats, motorcycles and ATVs. They are becoming quite popular for use in solar electric and other stand-by power applications. AGM batteries are found in standard automotive applications, where they are typically called maintenance free batteries.
Gel cell and AGM batteries are deep cycle batteries. Deep cycle means that they can withstand a higher range of discharge without suffering adverse affects. Standard lead acid starting batteries are not designed to be repeatedly discharged and recharged. Doing so will reduce the life of the battery. If your application requires longer discharge cycles before recharging, then a gel cell or AGM battery deep cycle battery is what you need.
If you want to know more about sealed lead acid battery, you can just visit Sentradaya, which is an excellent battery manufacturer. The company is a public company which has over 10 year’s history and it is very reliable and dependable. If you are interested in the company, you can search for more information in the internet.
Membuat solar cell / Panel Surya sendiri
Solar Cell atau panel surya adalah alat untuk menconversi tenaga matahari kedalam energy listrik. Solar Cell mulai popular akhir-akhir ini, selain mulai menipisnya cadangan enegy posil , isu global warming, energy yang dihasilkan juga sangat murah karena sumber energy (matahari) bisa didapatkan secara gratis.

Panel surya adalah alat yang terdiri dari sel surya yang mengubah cahaya menjadi listrik. Mereka disebut surya atas matahari atau “sol” karena matahari merupakan sumber cahaya terkuat yang dapat dimanfaatkan. Panel surya sering kali disebut sel photovoltaic, photovoltaic dapat diartikan sebagai “cahaya-listrik”. Sel surya atau sel PV bergantung pada efek photovoltaic untuk menyerap energi matahari dan menyebabkan arus mengalir antara dua lapisan bermuatan yang berlawanan. Continue reading
