How To Choose Colloid Lead-acid Battery

Types of Colloid
Now the colloid is roughly divided into several categories: first is Germany sunshine colloid cell membrane, second is domestic sodium silicate, silica, gas phase silica, third is the micro capsule class.
Macromolecule micro capsule is the hollow particles made of high polymer material and 3~40 microns spheres under high power microscope.
Macromolecule micro capsule is a material of hydrophilic group which will form glue that won’t leak even upside-down through reasonable ratio with sulfuric acid. Only when the liquid quantity is so much that beyond saturation of water absorbing groups will superfluous liquid dissociate.

Types of Plate
The battery plate including start type, UPS type and dynamic type is optimally designed according to the using conditions and requirements. Besides, dry load, less maintence, free maintence, interior chemosynthesis, exterior chemosynthesis are also the plate types. However, the real application need adjust to the region temperature.

Internal Resistant of Battery
The internal resistant of battery is related with relative capacity, thickness of the plate, specific gravity of electrolyte, internal pressure, temperature, clapboard, purity of the electrolyte. We cannot judge the quality of battery only by simple internal resistant. Only in the case of other conditions the same, battery internal resistance is relatively good as small as possible.

Lifetime of Battery
The service life of the battery which depends on equipments and technologies to assess is one of the main value of in the batteries. From the perspective of design and process testing requirements, lead powder, additive, plate, store, transportation, state of charge and discharge and many other factors have great influences on lifetime of battery. In addtion, some maintences should be done for operating environment, operating conditions, state of charging and discharding to prolong the lifetime.

Capacity of Battery
The capacity of the battery is the main criterion to measure the battery value directly. However, the level of battery capacity is not the only yardstick to decide the battery is good or bad. So when designing the battery capacity, additional operation environment should be considerated to balance performances as much as possible.
To reach the best operating effect, production, saling, operating should be considerated together. If possible, small checkout equipments, circulators can be equipped. Establishing a comparative life capacity dababase can purposefully test ech batch of battery.

Charging Accept Ability of Battery
Charing accept ability of battery is the rate to check the battery chemical reaction. The faster the reaction, the higher the conversion rate. The way to compare is putting several same type battery into different electrolyte. For instance, choose the same plate, add it in the glue and acid of same density and amount, detect the normal capacity standard and detect the capacity after 5A constant-current discharging and 10.5 ending at the same time.
A: acidity, 12AH, set filling power as 12AH, after downtime, the discharge capacity is 10.43AH, divide 10.43AH by 12AH, you get 86.92% which is the charging accept ability of the battery.
B: colloid, 12AH, set filling power as 12AH, after downtime, the discharge capacity is 11.42AH, divide 11.42AH by 12AH, you get 95.16% which is the charging accept ability of the battery.
As a result, for two kinds of battery, the electric quantity of acidity battery is 1.15 times than charging quantity, while colloid battery 1.05  under the condition of same discharing capacity. It’s evident that the charing accept ability of colloid battery is stronger than acidity battery.

Adaptability of Battery
Usually, the corresponding design and reasonable testing standards will be formulated in accordance with operating requirements in different regions. In tropical zones, the operating temperature is over 55°, while north America, northern Europe are below -20° which is the insurmountable limit of acidity battery. The operating temperature of acidity battery ranges from 50° to -18°, while colloid battery from 65° to -42°.

Resisting Capacity
Curing Process, structure and thickness of plate grid, assembly technique, clapboard and  exterior structure and many factor have effects on resisting capacity of battery. Usually, the resisting capacity of colloid battery is 3 times than acidity battery.
