Page 3: Important Safety Precautions
IMPORTANT SAFETY PRECAUTIONS Hazardous conditions may result if the charger is not installed or operated correctly. Please read the following instructions to prevent personal injury or damage to the charger. BATTERY RELATED • To reduce the risk of battery explosion, follow these instructions and those marked on the battery. -
Page 4: Description
DESCRIPTION SEC-1260A/SEC-1280A (for 12 V batteries) and SEC-2440A (for 24 V batteries) are high current, 3 Stage Chargers that deliver 60 A, 80 A and 40 A respectively for almost 75% to 80% of the charging cycle ensuring a very fast, safe and complete charging of lead acid batteries. -

Page 6: Specifying Lead Acid Batteries And Chargers
SPECIFYING LEAD ACID BATTERIES AND CHARGERS FLOODED / WET CELL AND SLA (SEALED LEAD ACID) BATTERIES There are two categories of lead acid batteries – Flooded/Wet Cell and Sealed Lead Acid (SLA). A flooded/wet cell battery has a high tolerance to overcharging. However, it will release hydrogen gas when charging that must be properly vented and the water level must be checked frequently. - Page 7 UNITS OF BATTERY CAPACITY The battery capacity is the measure of the energy the battery can store and deliver to a load. It is determined by how much current any given battery can deliver over a stipulated period of time. The energy rating is expressed in Ampere Hours (AH). For example, as one of the bench marks, the battery industry rates batteries at 20 hour rate i.e.
- Page 8 DEPTH OF DISCHARGE AND BATTERY LIFE The more deeply a battery is discharged on each cycle, the shorter the battery life. Using more batteries than the minimum required will result in longer life for the battery bank. A typical cycle life chart is given at Table 2 below: Table 2.
- Page 9 Parallel Connection Battery 4 Battery 3 Battery 2 Battery 1 Cable A 12V Charger Cable B Fig 2. Parallel Connection When two or more batteries are connected in parallel, their voltage remains the same but their AH capacities add up. Fig. 2 above shows 4 pieces of 12 V, 100 AH batteries connected in parallel to form a battery bank of 12 V with a capacity of 400 AH.
- Page 10 CAUTION! CAUTION When 2 or more batteries / battery strings are connected in parallel and are then connected to a charger (See Figs. 2 and 3 given above), attention should be paid to the manner in which the charger is connected to the battery bank. Please ensure that if the positive output cable of the battery charger (Cable “A”) is connected to the positive battery post of the first battery (Battery 1 in Fig.
- Page 11 CHARGING BATTERIES The batteries can be charged by using good quality AC powered battery charger or from alternative energy sources like solar panels, wind or hydro systems. Make sure an appropri- ate battery charge controller is used. It is recommended that the batteries may not be charged at current >...
