YUASA NP155-12 Valve Regulated Lead-Acid Battery 12V 155Ah Sealed UPS Batteries Rechargeable for Electronic Appliances

Battery Performance:

1. Simple maintenance: Since the gas generated inside the battery during charging is basically absorbed by the plate and reduced to electrolyte, there is basically no electrolyte maintenance phenomenon. It does not need to be replenished with water and charged equally like ordinary batteries. Maintenance is simple, and only the total voltage and appearance need to be checked regularly.

2. High liquid retention: The electrolyte is absorbed in a special separator and remains in a non-flowing state, so under normal operation, it can be used even if it falls down (it cannot be used if it falls down more than 90 degrees).

3. Excellent safety performance: If excessive gas is generated due to charging operation errors, it can be released to a certain extent to prevent the battery from rupture.

4. Very small self-discharge: The grid is produced using a special lead-calcium alloy to control the self-discharge to a minimum, and it can be stored for a long time.

5. Small internal resistance: Due to the small resistance, the larger the current discharge, the better the characteristics.

6. Excellent recovery performance after deep discharge: It is not good for the battery to connect the battery and the load for long-term discharge, but in case of this situation, as long as it is fully charged, there is basically no capacity reduction and it can be recovered quickly.

7. Long life and good economy: The grid is made of special lead-calcium alloy with good corrosion resistance, which has a long floating life. The gas generated during normal floating charge can be well absorbed, so under normal operation, there will be no capacity reduction due to the reduction of electrolyte. The special separator can retain the electrolyte and strongly compress the active material of the positive plate to prevent the active material from falling off, so the life is long. In addition, it also has a long cycle life during deep discharge. It is a very economical battery.
