When you count on your Battery, count on BD Batteries.

Crown Flooded Battery Maintenance Reccomendations:

* Newly purchased deep cycle batteries require a full charge before use.
* Add water as needed - do not overfill.
* Always keep electrolyte level above separator protectors.
* Keep vent caps tightly in place.
* Charge battery on properly matched charger.
* Allow battery to cool down before placing it back into service.
* Keep battery top clean, dry and free of foreign objects.
* Keep battery and truck cover open during charging.
* Batteries produce explosive gases. Keep flame and sparks away from battery.
* Do not discharge beyond 80% (1.140 -1.160 SP.GR.)
* Report any problems or damage. Minor problems can become major ones.
* Good battery care is not a luxury, it's a necessity!!
* New batteries need to be cycled several times (20 - 50 cycles, depending on type) before reaching full capacity. Batteru usage should be limited during this period.
* Battery connectors should be kept tight at all times. Sparks, burns, and fires can result from poor battery connections. Periodic inspection, and immediate replacement of faulty wires and lugs is recommended.
* Battery vent caps should remain in place and tight at all times during vehicle / stationary system operation and or charging.
* All Batteries should be kept clean, free of all dirt, corrosion, residue, grease, and other contaminants.
* Batteries should be routinely watered after charging. Older, neglected, and deeply discharged batteries sometimes need water prior to charging, check to see if the plates are exposed before starting a charge routine. Plates should be covered by approximately 1/8" of electrolyte. Add water if they are exposed. The electrolyte level in the battery's cells should be kept 1/4" below the bottom of the fill well.
* Distilled or treated water should be used to replenish batteries. Care should be taken to avoid metallic contamination (iron). This and other mineral contaminants severely shorten battery life.
* Batteries should not be discharged below 80% of their rated capacity for best battery life. Proper battery charging will help avoid excessive discharge.
* As batteries age, their maintenance requirements changes as well. It is not unusual for older batteries to need water more often and require longer charging times. Diminished capacity is also a result of battery aging.
* Batteries should be brought up to full charge as soon as possible after each discharge and every discharge. A happy battery is a charged battery. Avoid operating batteries in a partially charged condition, doing so will reduce the battery capacity and shorten battery cycle life span.
* Avoid charging batteries above 120°F or ambient temperature, whichever is higher.
* Periodic testing is an important preventative maintenance procedure. Hydrometer readings of each cell while fully charged gives an indication of balance and true charge level. Imbalance could mean one of three things and should be corrected immediately with an equalizing charge (charged fully). This condition is the result of a weak charger, incomplete charging routines, or a bad cell due to sulphation. Voltage tests (open circuit, charged and discharged) can locate a bad or weak battery/cell. 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 the battery is charged. An oversized charger will cause excessive gassing and heat which could cause explosions or other damage.
* Extreme temperatures can substantially affect battery performance and charging. The cold reduces battery capacity and retards charging. Heat increases water usage and can result in overcharging. Use safe procedures.
