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 wh...

Tteries reduction in usable capacity at higher discharge rates. As stated above, the rated capacity of the battery in ah is applicable at a discharge rate of 20 hours. As the discharge rate is increased, the usable capacity reduces due to “peukert effect”. This relationship is not linear but is more...

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. – typical cycle life...

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 appropriate battery charge controller is used. It is recommended that the batteries may not be charged at current...

Charging stages note! - voltage reading on no load . The output terminals of the charger consist of one common white / black negative terminal (3) and two red positive terminals (1, 2) for charging two banks of batteries. Each of the two positive terminals of the two banks has a schottky diode in se...

Battery voltages – charged and discharged conditions the cell voltage of a battery depends upon the temperature of the battery and has a negative temperature coefficient – the voltage level increases at lower temperature and decreases at higher temperature. The voltages are normally specified at 80º...

Stage 2 - constant overcharge voltage, timed absorption / boost charge mode (uo phase): when the charger enters stage 2 from stage 1, the battery is approximately 70% to 80% recharged. As soon as it enters this stage, a timer circuit is also initiated. The timer circuit can be selected to operate fo...

Caution! 3 stage charging is recommended for charging stand-alone unloaded batteries (there is no load connected to the battery when it is being charged). If a load is also connected simultaneously, a part of the charger’s output current will be diverted to this load. Thus, the charger may remain lo...

Protection the charger has the following protections: short circuit shut down in case of a short circuit on the output side, the output of the charger will be shut down. The charging indication led (4) on the front panel will turn red (on the remote panel (15), the red led “i phase” will light, the ...

Preparing the charger for operation ac input connection the charger is pre-set to operate from input ac voltage of 120 vac, 60 hz and is provided with a 6 ft attached cord with molded nema5-15p plug. Please ensure that the ac outlet is 2 pole, 3 wire grounding type – “nema5-15r” connecting the batte...
