Century Deep Cycle Batteries

Century’s Deep Cycle Batteries are designed to provide

longer life performance when continually discharged and

recharged, delivering energy for extended periods of time,

without sustaining life shortening damage such use would

cause to a standard automotive battery.

For steady power over a long period of time a Deep Cycle

battery is your best choice.

Typical applications include:

Mobility Scooters

Golf Carts

Camper Vans

Portable Lifting Equipment

Solar Heating

Hunting Spot Lighting

Marine Auxillary Equipment

Remote Area Power Systems

Portable Roading Systems

Inverter Integrated Systems

Portable Communication Systems

Choosing the right BatteryCentury Batteries provide a wide variety of products to suit many needs, ranging from Wet Flooded batteries to Sealed Gel products. Whatever your choice, it is important to have adequate capacity (Amp Hours) in the battery for the amount of power your application will use. You can work this out quickly and easily by establishing: the power consumption of each piece of equipment (marked in watts on the equipments’ information panel); the number of hours you will use between recharges; and the voltage of the system.

»

Now divide the total Watt Hours by the system voltage to obtain the Amp Hours.

498 Watt Hours / 12 Volts (12 volt system) = 41.5 Amp Hours

This figure is basically your guide to the battery size you need, after one more very important calculation. Electrical systems are not always perfect, so we strongly recommend you allow a little power in reserve. A 30% safety margin is a reasonable allowance for most applications. For larger more critical systems allow 50%.

Estimated Amp Hours (41.5) + 30% (12.45) = Total Amp Hours 53.95

Now you can select the correct battery for your needs simply by comparing your total calculated Amp Hours with the 20-hour capacity figures shown in the battery specification tables.

Note: the faster a battery is discharged, the fewer Amp Hours it will deliver before requiring a recharge. That is why Deep Cycle batteries carry Amp Hour ratings for various periods of discharge time. For each discharge rate and battery type, divide the Amp Hour capacity by the number of hours, to determine how many amps you can draw per hour per battery.

cell. Voltage checks (open circuit, charged and discharged) can locate a bad battery or weak battery. Load testing will pick out a bad battery when other methods fail. A weak battery will cause premature failure of companion batteries.

• Always use a matched voltage charger and battery pack system. An undersized charger will never get the job done, no matter how long you let it run. An oversized charger will cause excess gassing and heat; this situation could cause explosions or other damage.

• As batteries age, their maintenance requirements change. This means longer charging time and/or higher finish rate (higher amperage at the end of the charge). Usually older batteries need to be watered more often. And, their capacity decreases.

• Lead acid batteries should be brought up to full charge at the earliest opportunity. Avoid continuously operating batteries in a partially charged condition. This will shorten their life and reduce their capacity.

• Extreme temperatures can substantially affect battery performance and charging. Cold reduces battery capacity and retards charging. Heat increases water usage and can result in overcharging. Very high temperatures can cause “thermal run-away” which may lead to an explosion or fire. If extreme temperature is an unavoidable part of an application, consult a battery/charger specialist about ways to deal with the problem.

• Inactivity can be extremely harmful to all lead acid batteries. If seasonal use is anticipated, we recommend the following:

A) Completely charge the battery before storing.

B) Remove all electrical connections from the battery, including series/parallel connectors.

C) Store the battery in as cool a place as possible. However, do not store in a location which will consistently be below 0°C (32°F). Batteries will discharge when stored, the lower the temperature the lower the self discharge.

D) When not in use, boost every two months.

• New batteries should be given a full charge before use.

• New deep cycle batteries need to be cycled several times before reaching full capacity (50 - 125 cycles, depending on type). Usage should be limited during this period.

• Battery cables should be intact, and the connectors kept tight at all times. Systematic inspection is recommended.

• Vent caps should be kept in place and tight during vehicle operation and battery charging.

• Batteries should be kept clean and free of dirt and corrosion at all times.

• Batteries should be watered after charging unless plates are exposed before charging. If exposed, plates should be covered by approximately 1/8” of acid. Check acid level after charge. The acid level should be kept 1/4” below the bottom of the fill well in the cell cover.

• Water used to replenish batteries should be distilled or treated not to exceed 200 T.D.S. (total dissolved solids...parts per million). Particular care should be taken to avoid metallic contamination (iron).

• For best battery life, batteries should not be discharged below 80% of their rated capacity. Proper battery sizing will help avoid excessive discharge.

• Battery chargers should be matched to fully charge batteries in an eight hour period. Defective chargers will damage batteries or severely reduce their performance.

• Avoid charging at temperatures above 49°C (120°F) or ambient, whichever is higher.

• Deep cycle batteries need to be equalized periodically. Equalizing is an extended, low current charge performed after the normal charge cycle. This extra charge helps keep all cells in balance. Actively used batteries should be equalized once per week. Manually timed chargers should have the charge time extended approximately 3 hours. Automatically controlled chargers should be unplugged and reconnected after completing a charge.

• In situations where multiple batteries are connected in series, parallel or series/parallel, replacement battery(s) should be of the same size, age and usage level as the companion batteries. Do not put a new battery into a pack which has 50 or more cycles. Either replace with all new or use a good used battery(s).

• Periodic battery testing is an important preventative maintenance procedure. A hydrometer reading of each cell (fully charged) gives an indication of balance and true charge level. Imbalance could mean the need for equalizing and is often a sign of improper charging or a bad

• Charging parameters may vary according to environmental usage and equipment factors. Two or three stage constant voltage chargers are recommended for batteries used in Deep Cycle applications.• Vessels and vehicles with dual battery systems require specialist battery isolation systems (refer to “The Importance Of Battery Isolation”) and a qualified marine or automotive electrician should be consulted.• Marine chargers should be fitted with isolated transformers and the AC shore power circuit should be fitted with galvanic isolation.
