The American PowerSafe Enos has good safety performance and a lean liquid design. All the electrolyte in the battery is adsorbed by the electrode plate and ultra-fine glass fiber partition. There is no free flowing electrolyte inside the battery, and under normal use, there is no electrolyte leakage. It can be installed 90 degrees sideways and used normally. The valve controlled sealed structure ensures safety by automatically opening the safety valve when the air pressure inside the battery is occasionally high. The accumulation of flammable and explosive gases inside is minimal, and the explosion concentration cannot be reached, resulting in good explosion-proof performance.

Due to the use of high-purity raw materials, long-life formulas, and consistent control processes for battery packs, the normal float charging design life of battery packs can reach 7-10 years (≥ 38Ah).

The maintenance free performance utilizes the cathode absorption sealing maintenance free principle, with a gas sealing composite efficiency of over 95%. Under normal use, there is very little water loss, and the battery does not require regular liquid replenishment and maintenance. Green and environmentally friendly. Under normal charging, there is no acid mist, which does not pollute the computer room environment and does not corrode the equipment in the computer room.

① Control from the weight and thickness of the grid and the amount of paste applied; ② Before final assembly, the plates are weighed and graded one by one (for batteries with a capacity of ≥ 38Ah) to ensure relative consistency in the amount of active substances in each individual cell; ④ Before going offline, discharge the battery and perform a primary grouping of capacity and open circuit voltage; ⑤ ≥ The static period testing of 38Ah batteries before leaving the warehouse, after 7-15 days of "time test", can effectively detect very few suspicious batteries that are difficult to detect when going offline; ⑥ When leaving the warehouse, secondary grouping is carried out based on the open circuit voltage and internal resistance of the battery. 1. Good safety performance: Under normal use, there is no electrolyte leakage, no battery expansion or rupture.

2. Good discharge performance: stable discharge voltage and smooth discharge platform.

3. Good vibration resistance: The fully charged battery is completely fixed and vibrates for 1 hour at a frequency of 16.7Hz with a 4mm amplitude. There is no leakage, no battery expansion or rupture, and the open circuit voltage is normal.

4. Good impact resistance: The fully charged battery falls naturally from a height of 20cm onto a 1cm thick hard wooden board three times. No leakage, no battery expansion or rupture, normal open circuit voltage.

5. Good over discharge resistance: A fully charged battery at 25 degrees Celsius is subjected to constant resistance discharge for 3 weeks (with a resistance value equivalent to the 1CA discharge requirement of the battery), and the recovery capacity is above 75%.
