YUASA's NP series batteries are characterized by high performance, economical maintenance, and labor-saving features that meet the requirements of our customers. With the rapid development of electronic technology, Yuasa NP series maintenance-free valve regulated lead-acid batteries have been more widely used, and get the majority of users praise. Features: 1. Simple maintenance When charging, most of the oxygen generated inside the battery is absorbed by the pole plate and reduced to electrolyte, basically there is no electrolyte reduction. 2. The electrolyte is absorbed in the special partition and remains in a non-flowing state, so it can be used even if it is poured down. (Cannot be used even if it is poured over 90 degrees.) 3. Excellent safety performance. Excessive gases caused by extreme overcharging due to operational errors can be discharged to prevent the battery from rupturing. 4. Self-discharge is minimal. Special lead-acid alloy is used to produce the grids to minimize self-discharge. 5. Long life, good economy, the battery's grid is made of special lead-calcium alloy with good corrosion resistance, at the same time, it adopts special spacer which can keep the electrolyte, and at the same time, it presses the active substance of the positive plate with strong pressure to prevent it from falling off, so it's a kind of battery with long life and good economy. 6. Small internal resistance, due to small internal resistance, high current discharge characteristics. 7. Excellent recovery ability after deep discharge In case of long term discharge, as long as the battery is fully charged, the capacity will not be reduced and it can be recovered soon.
