High quality and more manageable Maintenance free 12v solar battery

EverExceed SPL series is a powerful combination of proven pocket-plate construction and advanced design from the world leader in industrial nickel-cadmium battery technology. With a 20-year life and ultra-low maintenance requirements, EverExceed SPL series has become the cost-effective first choice – worldwide – for trouble-free standby power in the most demanding applications.

More Reliable
SPL series can continue to supply power for 20 years or more thanks to its corrosion free construction and EverExceed’s tried and tested pocket-plate technology. No physical plate degradation and no sudden death with resulting costly downtime

Low life-cycle Cost
The cost of ownership of a battery system can be calculated across three distinct phases: the initial investment, including the cost of purchase and installation; on-going maintenance costs, including unexpected and expensive downtime periods; finally, the battery replacement costs, which include the expense of disposal as well as renewal. SPL series is the most cost-effective solution for any application – onshore or offshore – where long battery life, low maintenance costs, resistance to corrosion and total reliability are prime operating requirements.

More Adaptable
Offshore oil and gas, emergency lighting, fire and security, telecoms, utilities, photovoltaics. You can depend upon SPL series for perfect peace of mind.
No Water Filling
No water filling is necessary during the SPL series 20-year service life because of the controlled recombination and the valve regulated venting system (topping-up is possible if required).
More Durable
SPL series will survive treatment which would destroy lead acid batteries. This battery accepts ripple currents up to 0.2 C5 A and can be over-discharged or reversed without damage. Prolonged abusive overcharge can easily be compensated by refurbishment with water.

More Environmentally Tolerant
SPL series performs in the most severe conditions and can operate over a temperature range from 0  ºC to +40  ºC(+32  ℉ to +104  ℉). It can survive extremes of temperature from as low as –50  ºC to as high as+70  ºC (–58  ℉ to as high as +158  ℉).

Meeting International Standards
EverExceed batteries are manufactured under a strict ISO 9001 regime. Highest quality materials and rigorous quality
checking procedures ensure all relevant international standards are met, including IEC 60623-2001, IEC 62259-2003.

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.
