Invented by the French physician Gaston Plante in 1859, lead acid batteries were the first rechargeable batteries for commercial use. Lead acid batteries should be charged in three stages, which are [1] constant-current charge, [2] topping charge and [3] float charge.
The battery is fully charged when the current drops to a pre-determined level or levels out in stage 2.
During the constant-current charge, the battery charges to 70 percent in 5–8 hours; the remaining 30 percent is filled with the slower topping charge that lasts another 7–10 hours.
The switch from Stage 1 to 2 occurs seamlessly and happens when the battery reaches the set voltage limit. Once fully charged through saturation, the battery should not dwell at the topping voltage for more than 48 hours and must be reduced to the float voltage level. 12 volt battery charge discharge indicator - 2" 12 volt battery discharge indicator gauge covers your purchase price and original shipping.

In spite of the fact that it is one of the oldest types of batteries, lead acid batteries continue to be in wide use today, for various reasons. The engineers argued that the term “sealed lead acid” is a misnomer because no lead acid battery can be totally sealed. The charge time of a sealed lead acid battery is 12–16 hours, up to 36–48 hours for large stationary batteries. The constant-current charge applies the bulk of the charge and takes up roughly half of the required charge time; the topping charge continues at a lower charge current and provides saturation, and the float charge compensates for the loss caused by self-discharge. The topping charge is essential for the well-being of the battery and can be compared to a little rest after a good meal. The current begins to drop as the battery starts to saturate, and full charge is reached when the current decreases to the three percent level of the rated current.

Lead acid batteries are very dependable and much cheaper with respect to the cost-per-watt. This is true and battery designers added a valve to control venting of gases during stressful charge and rapid discharge.


With higher charge currents and multi-stage charge methods, the charge time can be reduced to 10 hours or less; however, the topping charge may not be complete. If deprived, the battery will eventually lose the ability to accept a full charge and the performance will decrease due to sulfation.
A battery with high leakage may never attain this low saturation current, and a plateau timer takes over to initialize the charge termination. Charging beyond what the battery can take turns the redundant energy into heat and the battery begins to gas. Titik yang dipilih saklar tersebut diatur ke 14 Volt untuk Accu 12 Volt dan 7,5 Volt untuk accu 6 volt.
Very few types of batteries can deliver bulk power as cheaply as lead acid batteries, and this makes the battery cost-effective for auto-mobiles, uninterrupted power supplies (UPS), golf cars, and forklifts. Rather than submerging the plates in a liquid, the electrolyte is impregnated into a moistened separator, a design that resembles nickel- and lithium-bases system. Rangkaian Charger Baterai Otomatis Dengan IC 555 ini menggunakan relay sebagai pemutus arusnya.
This enables to operate the battery in any physical orientation without leakage. Driven by these advantages, several types of sealed lead acid have emerged and the most common aregel, also known as valve-regulated lead acid (VRLA), and absorbent glass mat (AGM). Rangkaian Charger Baterai Otomatis Dengan IC 555 ini dapat digunakan untuk mengisi accu 12 volt dan 6 volt, tergantung dari seting titik referensi dan pemilihannya. Rangkaian ini dilengkapi saklar Starter charging yang berfungsi untuk memulai proses pengisian accu tersebut.
The universal battery charger using Lm317Here comes very simple idea is the universal battery charger circuit. The SCR1 (Silicon controlled rectifier) turn off, then not has a bias current path to ground. Automatic Charger and Full charged indicator using LM317K-TL431This is circuit Automatic Charger and Full charged indicator. There is a tube LED show the work with use integrated number circuit LT431 perform check the level , voltage battery and systematically protect short circuit with IC LM317.
