Outback F4-2.5L (2008)
1. Specific gravity of electrolyte should be held within the specific range from 1.250 to 1.290 for one hour or more.
2. Voltage per battery cell should be held at a specific value in a range from 2.5 to 2.8 V for one hour or more.
2. CHECK CONDITION OF CHARGE WITH HYDROMETER
3. NORMAL CHARGING
Charge the battery at the current value specified by manufacturer or at approximately 1/10 of battery's ampere-hour rating.
4. QUICK CHARGING
Quick charging is a method that the battery is charged in a short period of time with a relatively large current by using a quick charger.
Since a large current flow raises electrolyte temperature, the battery is subject to damage if the large current is used for prolonged time. For this
reason, the quick charging must be carried out within a current range that will not increase the electrolyte temperature above 40 °C (104 °F).
Also the quick charging is a temporary mean to bring battery voltage up to some level, and battery should be charged slowly with low current as a
rule.
CAUTION:
-
Observe the items in 3. NORMAL CHARGING.
-
Never use 10 A or more when charging the battery because it will shorten the battery life.
