    than a couple of times For applications where both engine starting and light deep cycling are required a dual purpose battery is often used This type of battery is neither a starting nor a deep cycle battery but rather a compromise between the two so it performs both functions adequately Can I use my deep cycle battery as a starting battery deep cycle batteries can be used for engine starting but starting batteries should not be used for deep cycle applications A deep cycle battery may have less cranking amps per pound than a starting battery but in most cases a deep cycle battery is still more than adequate for the purpose of starting an engine What are the advantages and disadvantages of gel AGM and flooded lead acid deep cycle Generally gel and AGM batteries have about 20 less capacity cost about two times more and have a shorter cycle life than comparable flooded lead acid batteries However Gel and AGM batteries do not need watering are safer no acid spilling out can be placed in a variety of positions have a slower self discharge characteristic and are more efficient in charging and discharging than flooded batteries see table

    when equalization is needed For example it is time to equalize if the measured specific gravity values are below manufacturer s recommended values after charging recommended value for Trojan deep cycle batteries is 1 277 007 at 80o F Equalizing is also required if the specific gravity value of any individual cell varies 30 points or more Reduced performance can also be an indicator that equalizing is necessary Equalization should also be performed when individual battery voltages in a battery pack range greater than 0 15 volts for 6 volt batteries or 0 30 volts for 12 volt batteries Does my deep cycle battery develop a memory Lead acid batteries do not develop any type of memory This means that you do not have to deep discharge or completely discharge a battery before recharging it For optimum life and performance we generally recommend a discharge of 20 to 50 of the battery s rated capacity even though the battery is capable of being cycled to 80 Do batteries self discharge when not in use All batteries regardless of their chemistry self discharge The rate of self discharge depends on the type of battery the age of the battery and the storage temperature the batteries are exposed to As an estimate Trojan batteries self discharge approximately 4 per week at 80o F What type of charger should I buy An automatic charger offers the greatest convenience Just plug the battery into the charger and the charger does the rest Manual chargers although equally effective at charging batteries require a greater level of attention Generally speaking automatic chargers are priced higher than manual chargers What size charger should I buy A properly sized charger takes into account battery capacity and the time interval between charges In applications where cycling is infrequent such

    lbs Stud 120 180 in lbs LT 100 120 in lbs VRLA Button 90 to 100 in lbs LT 100 120 in lbs WARNING Do not overtighten terminals Doing so can result in post breakage post meltdown and fire Can a battery freeze The only way that a battery can freeze is if it is left in a state of partial or complete discharged As the state of charge in a battery decreases the electrolyte becomes more like water and the freezing temperature increases The freezing temperature of the electrolyte in a fully charged battery is 92 0oF At a 40 state of charge electrolyte will freeze if the temperature reaches approximately 16 0oF What is the specific gravity of a fully charged battery A hydrometer reading of 1 277 or greater indicates full charge for Trojan batteries This value is based upon a specified temperature of 77 to 80oF For temperature correction values see the Temperature section of this FAQ What are common mistakes made by lead acid battery owners Undercharging Generally caused by not allowing the charger to restore the battery to full state of charge after use Continually operating the battery in a partial state of charge or storing the battery in a discharged state results in the formation of lead sulfate compounds on the plates This condition is known as sulfation Both of these conditions reduce the battery s performance and may cause premature battery failure Undercharging will also cause stratification Overcharging Continuous charging causes accelerated corrosion of the positive plates excessive water consumption and in some cases damaging temperatures within a lead acid battery deep cycle batteries should be charged after each discharge of more than 50 of the batteries rated capacity and or after prolonged storage of 30 days or more Under watering In

    for recycled waste water uses In some cases the electrolyte is cleaned and reprocessed and sold as battery grade electrolyte In other instances the sulfate content is removed as Ammonia Sulfate and used in fertilizers The separators are often used as a fuel source for the recycling process Where do I recycle my old batteries Old batteries may be returned to the battery retailer automotive service station a battery manufacturer

    reduced by 10 How do I account for temperature when taking my gravity readings Temperature will affect specific gravity readings As temperature increases the electrolyte solution expands and as temperature decreases the electrolyte solution contracts As a result it is a good practice to temperature correct specific gravity readings Here are the relationships Trojan recommends using For every ten degrees above 80oF add 3 points to the hydrometer reading Example 90oF the hydrometer reads 1 250 The actual reading 1 250 003 1 253 For every ten degrees below 80oF subtract 3 points from the hydrometer reading Example 70oF the hydrometer reads 1 250 The actual reading 1 250 003 1 247 How do I account for temperature when taking my voltage readings Temperature will affect voltage readings As temperature increases voltage decreases Conversely as temperature decreases voltage increases Here are the relationships Trojan recommends using For every 10 degrees below 80oF add 028 volt per cell to the charger voltage setting Example A 12 volt battery 70oF The recommended charging voltage 80oF is 14 60 volts The adjusted charging voltage is 14 60 6 cells 028vpc 14 77 volts For every 10 degrees above 80oF subtract 028 volt per
