Battery Protector for Emergency Lamp

Emergency lamps do not have a facility to prevent the deep discharge of battery if the lamp remains on during day time. The fluorescent lamp filament also damages if it is glowing in low battery voltage. This causes blackening of the filament side that indicates the damaged filament. So we have to switch off the lamp in the morning and switch it on again in the evening. By adding this circuit in the emergency lamp, you can reduce the job of daily switching. This circuit offers two advantages

1. It prevents unnecessary discharge of battery during daytime
2. It charges the battery only during night. This save energy and prevents overcharging of the battery.

Know the maintenance of Lead Acid Battery

A lead acid battery is composed of series of plates immersed in a solution of Sulphuric acid. Each plate has a Grid on which the active material is attached. In the negative plate, lead oxide is attached as the active material while on the positive plate, pure lead is attached. All the negative plates are connected together. Similarly all the positive plates are also connected together.

How to select best Inverter?

“My Inverter is not giving sufficient backup”. This is the most common complaint raised against the home inverter system. We expect maximum backup time from the inverter system with a tubular battery, but unfortunately we get half or less backup time than we expect. What is the reason for that? Before blaming the inverter, let us see what is happening.
