BATTERY — Battery Test and Charging Chart (Cont'd) — Slow Charge
EL-20flowchartK11's typical battery is 34B19 → 5.0 A slow-charge initial current. Slow-charge sequence: 30-min check (12-15 V) → 12 h main charge → SG re-check → up-to-5 h top-up → capacity test.

NOTE
• Check battery type and determine the specified current using the table shown above.
• After starting charging, adjustment of charging current is not necessary.
CAUTION
a. Set charging current to value specified. If charger is not capable of producing specified current value, set its charging current as close to that value as possible.
b. Keep battery away from open flame while it is being charged.
c. When connecting charger, connect leads first, then turn on charger. Do not turn on charger first, as this may cause a spark.
d. If battery temperature rises above 60°C (140°F), stop charging. Never charge battery when its temperature is above 60°C (140°F).
