Yuasa YBX3075 12V 60Ah 550A SMF Battery

Product Information

Stop charging if the battery begins to gas freely (some gassing is normal during the last stages of charging) or if the battery temperature rises above 50°C. B. These chargers should be able to charge over discharged (below 11.00V) batteries. Note that some have a special setting for all-calcium batteries. Constant Current Chargers When fitting the charger to the battery, connect the positive lead to the positive terminal and the negative lead to the negative terminal. A. Boost charging is not recommended except in exceptional circumstances e.g. a stranded customer, as this will reduce battery life, especially if a battery is boost-charged more than once. B. Never boost-charge any battery that is below 11.00 Volts as it will be too sulphated to accept a charge; scrap the battery or charge normally.

Note. Many customers severely underestimate the amount of time necessary to charge a flat battery. This results in customers returning batteries saying that they have charged the battery but that it is still not holding charge. There are many types of charger available; their working principles and the procedure for using these is given below. Smart Chargers These provide a very high initial current, and are used mainly to put some charge into a flat battery when it is needed urgently by the customer. The current falls as the battery state-of-charge increases, and the battery temperature is monitored to make sure it does not overheat. A. Ideally, charge each battery on a separate charger unit. If this is not possible, charge batteries in series. We do not recommend charging batteries in parallel because it is not possible to control the amount of current passing through each battery. If batteries in different states-of-charge are being charged in series, each battery should be removed as soon as it is charged. (If you wait until the last battery is charged, some of the batteries will be overcharged).These maintain a fixed, constant, pre-set voltage throughout the charging period. The current cannot be set and will fall as the battery state-of-charge increases. Yuasa are one of the world's largest manufacturers and suppliers of valve regulated lead-acid batteries with global manufacturing plants and an extensive marketing and distribution network throughout the UK and Europe. D. Charge the battery for the number of hours shown in the table below depending on the open-circuit voltage.

E. If you are charging a battery below 11.00V (over discharged) that has been in service, a specialised charger capable of providing a very high charging voltage may be necessary, and the recommended current may not be obtainable at first. In this case, monitor the current and adjust as necessary during the charge. If a battery has become over discharged, it will have lost both life and performance because of irreversible sulphation. Charging may reduce further its potential life. Constant Potential Chargers Switch on the charger. See below for the correct charging conditions depending on your type of charger. B. Stop charging when the battery is gassing freely and the battery-voltage shows no increase over a period of at least 2 hours.These maintain a fixed, constant, pre-set current throughout the charging period irrespective of the battery on-charge voltage. Do not charge AGM batteries on a constant current charger. We receive data from battery manufacturers and this may be subject to change and / or manufacturing tolerances.
