FAQ

Prime Products FAQ Info and support.

 

What is Calcium battery?

It is a new generation Lead acid battery added the Calcium content to the Lead plate either just one plate (called Calcium hybrid ) or both plate (Calcium -Calcium).:

---Low self discharge rate, which extend the shelf life of battery.

---Lower internal resistance which provided a small increase in CCA performance.

---The ability to withstand higher engine bay temperature.

---More reliable than common Lead acid battery.

 

What is Gel battery?

Gelled electrolyte (GEL) battery

---It is put into the thixotropic gelled electrolyte.

---To be sealed with special pressure valves.

---Fully maintenance-free and without needing of compensating the electrolyte.

---Use the recombination reaction to prevent the escape of hydrogen and oxygen gas lost in a flooded lead acid battery.

---It is a storage battery for starting or deep cycle application.

 

What is AGM battery?

Absorbed Glass Mat (AGM) battery

--- The electrolyte absorbed in separators consisting of a sponge-like mass of matted glass fibers.

---To be sealed with special pressure valves.

---Fully maintenance-free and without needing of compensating the electrolyte.

---Use the recombination reaction to prevent the escape of hydrogen and oxygen gas lost in a flooded lead acid battery.

---It is a storage battery for starting or deep cycle application.

 

Why Prime chargers provide a Thermal run away protection?

The proper charge voltage relates to the battery temperature, a warmer battery requires a reduced voltage, otherwise, it may bring a destructive result if the charging current increased, the battery heating will be increased under a loop feeding on itself.

 

   To be prevented Thermal run away for a battery, the Prime smart chargers used unique programmed charging algorithm to monitor the relationship between the CV voltage and charging current; If detected the Thermal run away occurred, the charger will promptly switch to Float charging stage or shut down the charging progress; Also, the maximum charging timer built into program. And the temperature sensor is an option for users to monitor the battery temperature as well on Prime smart  battery chargers series.

 

 Why Prime chargers automatically run an equalizing charging mode when users select Calcium battery type?

Because of the different chemistry that makes a Calcium battery as above introduce, a specially Equalizing charging method which push up the battery voltage to 16.2V with a small charging rate is needed, this charging algorithm can fully recharge and restored the Calcium battery, especially when the calcium battery suffers a deeply discharged or be used heavily .

 

Why Prime Chargers engage a Manual Equalizing feature?

For a Lead acid battery, aging affects each cell differently, since the cells are connected in series, controlling the individual cell voltage during charge is virtually impossible, even if the correct overall voltage is applied; a weak cell or poor condition cell will generate its own voltage level and will intensify the condition further, so, an additional Manual Equalizing charging mode is built on Prime switching mode series chargers, they are used with a high voltage charging to balance the voltage of each cell, reverse the high concentration of electrolyte at the bottom, minimize the battery cell voltage variation, bring all cells to equal charging state.

 

Why Prime chargers provide Rejuvenation for poor conditional battery?

If a Lead acid battery is left unused for long periods or usually at under-charge, the battery will tend to deteriorate, the plates "sulphate" and reduces the Amp Hour rating. Prime switching mode chargers provide an unique charging method which is used a special charging Pulse to rejuvenate (refresh) to the battery, it can efficiently break down the crystalline form of Lead sulphated within battery cells, prolong the battery life.

 

What is advantage of Prime battery isolator comparing to other brands of conventional isolators?

People always use and charge auxiliary batteries in their cars and caravans to run many electronic appliance in these days, so, need to look for an ideal battery isolators to prevent from over-discharging the main battery for Engine start, Prime fully automatic electronic battery isolator with automatically sensing the battery voltage and fully isolate between the main battery and auxiliary battery, it appears the following advantages.

---Conventional Solenoid isolator is just an electronic switch that can handle large (charging) currents, it connects both batteries ( Main battery and auxiliary battery when the engine is turned on, it will turn off when the engine is shut down, it is cheap and exist so many years but it is not far from ideal.

---Conventional Diode isolator.

This type of isolator is basically two very high current diodes in a heat sinkbut many of the diode based isolators cause a 0.4 to 0.6 volt loss which means that the batteries will not charge to as high a voltage as when they are connected directly to the alternator.

--- Prime Electronic isolator is designed to automatically charge and isolate the main battery and auxiliary battery according to battery voltage sensed. It also can operate as an emergency jumpstart by manual override from auxiliary battery in case of main battery flat.

---Prime isolator is designed for battery to battery isolator, it is not directly connect to the Alternator, the unit can be suitable for any types of battery, such as Gel, AGM, WET and Calcium battery; Also, the isolator is designed to be controlled over current by electronic circuit, thus, don't need to worry about overheating inside the units.
