The block battery - for dependability

The wide range of low, medium and high capacity types makes accurate selection easy, based on discharge time and end of discharge voltage. Robust construction and generous electrolyte reserve enable the battery to withstand wide temperature fluctuations in stationary cycling behaviour over its 20+ years' life.

Built with a future Nickel-cadmium plates are completely reliable, with no risk of thermal runaway or sudden death. Generally operating between temperatures of 40 ºC to +60 ºC(-4  ℉ to +140  ℉), they can tolerate extremes of -50 ºC to +70 ºC(-58 ℉ to +158  ℉)  for short periods.
With only periodic checks, the block battery will provide up to 20+ years' completely faithful service.

Trouble-free long cycle life
The EverExceed nickel-cadmium block battery's unique electrochemistry enables it to regularly withstand any depth of discharge.
Following a deep discharge the block battery is designed to recharge very quickly and economically, using standard single or two-level charging equipment.
Be sure of a low overall cost
The Ni-Cd block battery is the most highly cost-efficient solution to stored power requirements.

• No downtime
• No replacement costs
• Minimal maintenance
• Ease of installation
• 20+ years' operating life

Easy storage and installation
Nickel-cadmium block batteries are quick and easy to install as original equipment and may be stored for many years in a discharged state under correct conditions.
On installation a simple bolted connector enables the battery to be rapidly commissioned.
Assured reliability
Ni-Cd is equally dependable in controlled city environments or harsh, unpredictable conditions in the world's most remote
and unpopulated areas. The Ni-Cd battery's block construction makes it highly resistant to electrical abuse and transport over rough terrain, precluding risk of subsequent failure.
Optimized for performance:
An electrolyte solution of potassium hydroxide and a small amount of lithium hydroxide acts only as an ion transfer medium, delivering optimum performance without causing base material degradation.
Good reserves and circulation of the electrolyte are achieved
by a wide inter-plate space. Injection moulded plastic grids both separate plate and insulate plate edges. For extremely low temperatures a special high density electrolyte is available.
The block battery is fitted with a specially designed flame arresting flip top vent and does not produce corrosive vapours. The tough polypropylene casing ensures the battery's structural integrity throughout its long life.
Supports these Single Cell ranges with:

• Quality approved manufacture to ISO 9001 and the TUV certification.
• Single Cell batteries have been developed in line with the safety requirements of EN-50272-2 and components used (such as insulated cable connectors and end lug covers) are defined to ensure high protection against electric shocks (Ip2 level).
• Full recycling service to protect the environment.

The EverExceed Single Cell ranges fully comply and exceed the IEC 60623 standard requirements.

Performance Data

• High tolerance to electrical abuses such as overcharge and over discharge.
• High tolerance to rough handling and mechanical abuse due to strong components and robust construction.
• Trouble-free long cycle life .
• No risk of sudden death due to the chemistry and the cell structure.
• Wide operating temperature: -40°C to 60°C.
• Generous electrolyte reserve for long maintenance intervals.
• Clear (MBS) or translucent (PP) plastic cell case for easy electrolyte level inspection.
• Plastic grid spacers eliminate separator deterioration problem.
• Custom cell dimensions available.
• 20+ years service life in stationary applications.
• Conforms to IEC60623.

EBH Series nickel cadmium batteries are designed for general industrial applications where absolute reliability is a necessity. Service-proven pocket- plate technology ensures long uninterrupted battery life without the risk of sudden loss of power.
EBH Series batteries are suitable for high discharge rate applications (30 minutes and below) such as switchgear tripping, diesel engine starting, UPS, etc.

Q: What is an AGM battery?

A: An AGM battery is a lead-acid battery that is sealed using special pressure valves and completely maintenance-free. It has all of its electrolyte absorbed in separators consisting of a sponge-like mass of matted glass fibers, and uses a recombination reaction to prevent the escape of hydrogen and oxygen gases normally lost in a flooded lead-acid battery (particularly in deep cycle applications).

Q: What is a GEL battery?

A: A gel battery is a lead-acid battery that is sealed using special pressure valves and completely maintenance-free. It uses thixotropic gelled electrolyte and uses a recombination reaction to prevent the escape of hydrogen and oxygen gases normally lost in a flooded lead-acid battery (particularly in deep cycle applications).

Q: What is a NiCad Battery?

A: The nickel cadmium battery is a type of rechargeable battery using nickel oxide hydroxide and metallic cadmium as electrodes. EverExceed manufactures pocket plate and sintered plate nicad batteries.

Q: What is battery rating?

A: The most common battery rating is the Ampere-hour Rating. The capacity of a battery, in Ahs, is a dynamic number that is dependent on the discharge current.For example: 10 amperes for 20 hours (10 x 20) = 200 Ah @ the 20-hour rate.

Q: How can you tell if a VRLA battery has been damaged by under- or overcharging?

A: The only way is with a load test. Use the same procedure you would use with a wet cell battery:

a. Recharge if the open circuit voltage is below 75%.

b. If adjustable, set the load at 1⁄2 the CCA rating or three times the 20 hour rate.

c. Apply the load for 15 seconds. The voltage should stabilize above 9.6 volts while on load.

d. If below 9.6 volts, recharge and repeat test.

e. If below 9.6 volts a second time, replace the battery.

Q: How long does it take to recharge a fully discharged VRLA battery?

A: A specific time is difficult to determine because recharging depends on the following factors: depth of discharge; temperature; size and efficiency of the charger; age and condition of the battery.

Q: How do I select the right battery for my applications?
A: Proper battery selection may require the assistance of a knowledgeable battery sales or service technician. Please consult EverExceed for more details.
