Optima Red Top U 4.2 Car Battery, 8004-250, 12V, 50Ah, 815A

This high-end battery incorporates Spiracell (cells with spiral structure inside that enhances the performance of the batteries) created by OptimIn those applications where starting power is priority such as trucks, all -terrain vehicles, agricultural and construction machinery, emergency vehicles, generators and trams. They are batteries that last up to three times more and is up to 15 times more resistant to vibrations than other batteries.It is designed to spill -proof.And offers rapid recharge capacity to recover tension in a short time for short driving cycles. This battery is incredibly robust.Its power and durability are characteristics in which you can fully trust because it is designed to always offer the maximum starting power and, therefore, a reliable commissioning of the vehicle. Recharge time will vary according to temperature and charger characteristics. When using Constant Voltage chargers, amperage will taper down as the battery becomes recharged. When amperage drops below 1 amp, the battery will be close to a full state charge. Always wear safety glasses when working with batteries. Always use a voltage regulated battery charger with limits set to the above ratings. Overcharging can cause the safety valves to open and battery gases to escape, causing premature end of life. These gases are flammable! You cannot replace water in sealed batteries that have been overcharged. Any battery that becomes very hot while charging should be disconnected immediately.
