12V 70Ah Lead-acid EFB Battery For Start-stop System
In order to reduce the CO2 emissions of vehicles, the start-stop technology is adpoted. This technology is especially effective where the journey is frequently interrupted in a city or town where there are frequent pauses. Unfortunately, an unforeseen consequence was the effect on the vehicle’s SLI (starting, lighting, ignition) battery. There were several causes of failure: over-discharge, sulphation and PSoC related issues. The basic problem was that the batteries could not recharge sufficiently from the alternator in the time available when the car was being driven between stationary periods. However, the load on the battery continues from various devices which are still operating, e.g. radio, engine management, lights, air-con and even windscreen heating. During these stop periods, more energy is drawn out of the battery to power these devices, than is replaced by the alternator when the engine is running. Under these conditions, the battery will gradually be drained and will spend most of its life in a low state of charge with low SG electrolyte. Therefore, the EFB battery is applied to solve these problems. As an enhanced flooded battery, different with the traditional flooded battery, the EFB battery has improved charge acceptance and greater cyclic durability when operating in a reduced state of charge.
Product Features
Longer Service Life
The EFB battery can frequent start for more than 50,000 times.
Excellent Discharge and Charge Performance
It can provide excellent discharge performance and fast charging speed, which helps to save fuel consumption. With its excellent characteristics, the battery can be quickly restored to a fully charged state after the vehicle is started, and its low self-discharge rate enables long-term storage.
Adapt to Wide Temperature Range
The automotive EFB start stop battery has a stable performance under environment from -40℃~80℃.
Fuel Consumption Reduction
The fuel consumption reduced under comprehensive conditions and 80% of the capacity is restored after the engine is started, while also helping to save fuel by extending the life of other components in the vehicle.

FAQ
1. Why is there a possible battery explosion? And how do we
prevent it?
A: A lot of hydrogen and oxygen will be produced during the charging process of battery. When the concentration of the mixed gas reaches 4% in the air, if sparks generated due to loose wire connection or open fire from outside interferes, there is a possibility that explosion may occur, which will damage the battery or even injure people and things. Preventions are as below:
a. Control the power charged, avoid overcharge, to reduce the amount of gas degassed.
b. No open fire near the batteries during charging process and keep good ventilation.
c. During charging, the connection should be firm to avoid sparks due to loose connection.
d. Adopts constant current and limited voltage charging method, which generates less gas evolution.
e. Prevent sparks or even fire and explosion due to short circuit.
f. Keep the degassing hole unobstructed for the maintenance-free sealed batteries, otherwise, the increased internal pressure may accumulate too high to cause bulge or even explosion.
2. Why the capacity is decreased?
A: If battery shows insufficient capacity during usage, or capacity cannot meet rated capacity value, we should firstly consider the possibility of insufficient charge or insufficient recharge after usage. Check if the electrolyte density is too low, of if the electrolyte level increases after recharge.
a. Sulfation (over-charge, repeated charge, hydrotherapy for desulfurization)
b. Pollution of electrolyte (after multiple flushing with distilled water, change the electrolyte)
c. Whether batteries show partial short circuit.
d. Phenomena like grid corrosion, plate breakage, active mass shedding etc. at the end of service life.
