Flooded Batteries
Positive plate
The tubular plate construction incorporates low antimonial lead alloy spines in complete contact with the active material, which is retained by an outer gauntlet. This enables the electrolyte to penetrate freely, ensuring a high power output per unit volume.
The negative plate is of a highly porous paste on a lead alloy grid. This compliments the positive plate construction, providing a balanced performance and superior life.
The bolt-on connector facilitates easy cell replacement. Acid resistant, totally enclosed terminal post, maximum safety. Orifice for voltage readings.
Prevents possible shorting between plates due to active material shedding during the life of the cell.
Microporous polyethylene is specially calendered with ribs. Fully enclosed plates cannot develop “mossing” or shorts between the plates. Extended battery life is achieved using sleeved plates

A polypropylene pressure bushing seated on a rubber “o” ring, locked in place by a poly- carbonate ring. The cell lid is welded to the container, and polypropylene is injection moulded into the post to lid cavity. This design eliminates acid leaks through the post assembly.

Min/Max mark for clearly visible level reading as well as closed cell float that ensures accurate levels over the cell life.

Lead Acid Batteries
History of Lead Acid Batteries
As they are inexpensive compared to newer technologies, lead–acid batteries are widely used even when surge current is not important and other designs could provide higher energy densities. Large-format lead–acid designs are widely used for storage in backup power supplies in cell phone towers, high-availability settings like hospitals, and stand-alone power systems. For these roles, modified versions of the standard cell may be used to improve storage times and reduce maintenance requirements. Gel-cells and absorbed glass-mat batteries are common in these roles, collectively known as VRLA (valve-regulated lead–acid) batteries.
Both gel and AGM designs are sealed, do not require watering, can be used in any orientation, and use a valve for gas blowoff. For this reason, both designs can be called maintenance free, sealed and VRLA.

1. History of Lithium Ion Batteries
The term “lithium battery” refers to a family of different lithium-metal chemistries, comprising many types of cathodes and electrolytes but all with metallic lithium as the anode. The battery requires from 0.15 to 0.3 kg of lithium per kWh.
In 1980, the American physicist Professor John Goodenough invented a new type of lithium battery in which the lithium (Li) could migrate through the battery from one electrode to the other as a Li+ ion.
Lithium is one of the lightest elements in the periodic table and it has one of the largest electrochemical potentials, therefore this combination produces some of the highest possible voltages in the most compact and lightest volumes.
This is the basis for the lithium-ion battery. In this new battery, lithium is combined with a transition metal – such as cobalt, nickel, manganese or iron – and oxygen to form the cathode. During recharging when a voltage is applied, the positively charged lithium ion from the cathode migrates to the graphite anode and becomes lithium metal.
Because lithium has a strong electrochemical driving force to be oxidised if allowed, it migrates back to the cathode to become a Li+ ion again and gives up its electron back to the cobalt ion. The movement of electrons in the circuit gives us a current that we can use.
2. Types of Lithium Ion Batteries
- Lithium Cobalt Oxide: Used in cellphones due to very high capacity
- Lithium Manganese Oxide: Used in medical equipment due to high safety and stability
- Lithium Iron Phosphate: Used in energy storage and electrical vehicles due to high cycle life and safety
- Lithium Nickel Manganese Cobalt Oxide: Used in power tools due to good balance of specific energy and specific capacity
- Lithium Nickel Cobalt Oxide: Could be used in electric vehicles in the future as prices come down
- Lithium Titanate: Used in military and aerospace due to incredible fast charge and high energy density

3. Overview of Lithium Ion Batteries
High energy density: More energy with less weight
High charge currents: Shortens the charge period-essential for solar applications
High discharge currents: enabling for example electrical cooking on a small battery pack
Long battery life: Up to six times the cycle life of lead acid battery
High efficiency between chargeing and dis-charging: Very little heat generation
Higher continuous power available
A lead acid battery can fail prematurely due to sulphation if it is left partially charged, fully discharged, or rarely fully charged for long periods of time. A Lithium Iron Phosphate battery does not need to be kept fully charged, has a wide operating temperature range and excellent cycling performance. They are therefore THE battery for very demanding applications.
A typical “round trip” energy efficiency (energy that can be taken out of the battery compared to the energy required to -recharge) for lead acid batteries is ~70%. For a LiFePO4 battery it is >96%. The final 20% charge of Lead Acid battery is particularly inefficient with efficiency dropping to ~50% and can take a long time for the battery to become completely charged. In contrast, a LiFePO4 battery will always achieve >96% efficiency and can therefor be charged more quickly while wasting less energy.
LiFePO4 batteries save up to 70% in space and 70% in weight compared to lead acid.
It is vital that an advanced Battery Monitor System (BMS) is used to control the battery charging. This is important to actively balance the individual cells that make up the battery and prevent under or over voltage which can otherwise destroy the battery. It is also important for the battery to be able to communicate with the rest of the system.
4. Lithium Batteries Compared to Lead-Acid
Item | Description | Lithium Ion | Lead Acid |
Cycle life | Cycle life refers to the amount of charge and discharge cycles a battery can last, before reaching a fixed percentage of its original capacity. This is usually 60, 70 or 80% | Lithium Ion batteries will last between 5 000 and 7 000 cycles before reaching 70% of their original capacity. | Lead Acid batteries will last between 1000 and 2000 cycles before the need to be replaced. |
Depth of discharge | Depth of Discharge (DOD) is how deep a battery can be discharged per cycle. | Lithium Ion batteries can be cycled up to 90% (and even 100%). Typical systems are sized to cycle the battery to 70% for optimum life. | Lead acid batteries shouldn’t be discharged too deep before the cycle life is drastically impacted. Most systems are sized for a maximum of 50%. |
Discharge Efficiency | Discharge efficiency is the energy that can be extracted and used in a battery, measured as a percentage of the energy stored in the battery. | Discharge efficiency is the energy that can be extracted and used in a battery, measured as a percentage of the energy stored in the battery. | Discharge efficiencies of lead acid batteries are around 70 to 80%. This means for every 100A.h stored, between 20 and 30 W.h is wasted as heat. To use 100A.h, the battery needs to be oversize by an additional 20 to 30% to compensate for the losses. |
Charge Efficiency | Charge efficiency is an indication of the amount of energy needed from the source, in order to store the desired amount of energy in the battery. | Typical charge efficiency of a Lithium battery is also 98%. In order to store 100W.h of energy, you would need to produce a little more than 100W.h from your panels. | Charge efficiencies of lead acid batteries are around 70 to 80%. This means for every 100A.h stored, between 20 and 30 W.h is wasted as heat. To store 100A.h, the panels need to be oversize by an additional 20 to 30% to compensate for the losses. |
Price | The purchase price of Lithium Ion is steadily dropping due to improvements in technology and the distribution network world wide. Prices of Lead Acid batteries are steadily increasing due to the ever rising price in lead. | For a 52V, 100A.h Lithium battery, the price is between 2 and 3x more expensive than the equivalent Lead Acid battery bank with the same A.h rating and system voltage. | 4x Lead Acid batteries in series are required to have the same system voltage as an equivalent Lithium battery. |
All systems are sized to have about 4kW.h of usable power.
