CARING FOR YOUR FLOODED LEAD-ACID BATTERIES
CARING FOR YOUR FLOODED LEAD-ACID BATTERIES: FIRST, DO NO HARM.
Strange as it may sound, flooded lead-acid batteries are somewhat like plants. They need to be charged just as plants need to be fertilized. They need to be watered but not overwatered. They are affected by the temperature, and they need careful monitoring during dormant periods. Further, neglect and mistakes can damage or even kill them. Trojan Battery Company experts suggest steps you can take to prevent damaging your flooded lead-acid battery.
You probably know how important it is to properly maintain your flooded lead-acid battery. But you may not know the common maintenance mistakes that may damage or even destroy it. Yet knowing what NOT to do to your battery is as important as knowing what to do.
Many of these missteps occur around charging, watering, or storing. What’s more, the temperature can affect the battery's performance and maintenance needs and must be considered during these functions. See your user’s guide for more information about temperature compensation.
AVOID THESE CHARGING ERRORS
Proper charging is a key to battery performance and longevity, but it is something of a balancing act. Both under- and over-charging can reduce the performance and life of your battery.
for your battery. Otherwise, make sure the charger is set to the appropriate program for a deep-cycle flooded lead-acid battery. • Do not charge the battery unless the electrolyte covers the plates.
• Fully charge the battery before watering.
• Don’t forget to return your battery to a full state of charge after each use of 30 minutes or more. Remember to account for the cumulative times of shorter discharges as well.
• Limit the discharges to 50% or less for extended life and performance, if possible.
• Don’t forget to top off the charge every few weeks while the battery is not used for long periods.
• Never charge a frozen battery and avoid charging one at temperatures above 122o F (50o C). Remember, the warmer it
AVOID THESE WATERING ERRORS
Watering is also a balancing act, as both under- and overwatering can harm your flooded lead-acid battery.
The frequency of watering depends on usage, charging, operating temperature, and age of the batteries. Batteries need more water as they age and in hot weather. Underwatering is one of the most common causes of battery damage.
TO FIND YOUR SWEET SPOT:
• Don’t water uncharged batteries, except to bring the electrolyte level above the tops of the plates before charging. Fully charge the battery before adding water.
• Never let the electrolyte level fall beneath the top of the plates. This can irreparably damage your battery and prevent charging.
• Don’t neglect your batteries. Check levels and fill at regular
