Starter Battery-Maintenance Type (filler caps)

• Most commonly referred to as automobile/truck starter type. Least expensive (initial cost)
• Not to be used for non-starting type applications such as running lighting, deep cycling (trolling), fish finders, electronics.
• Must not be deeply discharged and should be re-charged immediately after being used.

TIP 1: Never use a battery rated only in Cranking Amps (CCA) for anything but starting.

TIP 2: Always charge a starter battery as soon after using it as possible.

TIP 3: Always purchase a maintenance type battery (w/ filler caps), if you plan to properly maintain your battery and are not concerned about locating/operating the battery in a confined area.

TIP 4: Always buy the largest/highest rated battery possible to reduce the depth of discharge in order to maximize its life and reduce total cost.

TIP 5: Always think of the cost of the battery you are going to buy in terms of performance, safety, and convenience. Total cost/cycle is what you should be concerned with, not just initial price.

TIP 6: If you are NOT planning on using your battery on a every day basis, such as in seasonal type equipment, be sure you have a means of keeping it fully charged for long periods with-out ever risking it being over-charged. Batteries kept at full charge at all times without being over-charged will last 3-5 times longer than those that are allowed to self-discharge.

Starter Battery – Sealed Gelled, AGM, or Dry (no filler caps -electrolyte is “non liquid”)

• Much more expensive than non-sealed liquid 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-discharge, which can cause serious damage and shortened battery life.
• Recommended for applications where little or no checking and/or maintenance can easily be performed.

TIP 8: Consider the potential benefits vs. cost of these types before making a buying decision.

TIP 9: Check the output of your alternator/generator-voltage regulator settings before replacing your standard liquid type battery with any non-liquid sealed type to be sure your charging system does not overcharge it.

TIP 10: 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 11: 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 12: 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 13: Knowing the exact voltage of your battery can help you to accurately determine it’s state-of-health.
