Outback F4-2.5L SOHC (2005)
1. Specific gravity of electrolyte should be held within the specific range from 1.250 to 1.290 for more than one hour.
2. Voltage per battery cell should be held at a specific value in a range from 2.5 to 2.8 V for more than one hour.
2. CHECK HYDROMETER FOR STATE OF CHARGE
3. NORMAL CHARGING
Charge the battery at current value specified by manufacturer or at approx. 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 degree C (104
degree F).
Also the quick charging is a temporary means to bring battery voltage up to a fair value and, as a rule, a battery should be charged slowly with a
low current.
CAUTION:
-
Observe the items in 3. NORMAL CHARGING.
-
Never use more than 10 A when charging the battery because it will shorten the battery life.
