Choosing the Right Battery for your Application- continued... Starter Battery - Sealed Gelled, AGM or Dry (no filler caps - electrolyte is non-liquid) * Much more expensive than non-sealed type. * Can be operated in any position without risk of spilling * Have a lower rate of self-discharge than non-sealed maintenance and/or maintenance-free (liquid) batteries. * Are considerably more sensitive to overcharging and self-discharging, which can cause damage and shortened battery life. * Recommended for applications where little or no checking and/or maintenance can easily be performed. TIP 1: Consider the potential benefits vs. cost of these types before making and buying decision. TIP 2: Check the output of your alternator/generator - voltage regulator settings before replacing your standard liquid type battery with any non-liquid type to be sure your charging system does not overcharge it. TIP 3: Never allow a sealed non-liquid battery to self- discharge below 11.5 volts or permanent damage can occur. Special charging equipment and/or procedures may be needed to recover sealed batteries that have been allowed to self-discharge below 11.5 volts. TIP 4: To prevent self-discharge during periods of non-use/ storage, maintain your battery using a constant voltage type charger with end of charge to prevent over/ under charge. TIP 5: Always use an accurate digital voltmeter or similar device to determine your sealed batteries true state of charge. Remember to let your battery REST for 12 hours or longer before testing its voltage. TIP 6: Knowing the exact voltage of your battery can help you accurately determine its state of health.
