Recharging
• When the battery is being activated, hydrogen and oxygen
gases in the battery are extremely explosive. Keep open
sparks and flames away from the battery at all times,
especially when charging the battery.
• When disconnecting the cable from the battery, start with
the negative terminal first.
When connecting the cable to the battery, start with the
positive terminal first.
• Never check battery charge by placing a metal object
across the posts.
Use a voltmeter or hydrometer.
1. To slow charge the battery (1), connect the battery positive
terminal (3) to the charge positive terminal and the negative (2)
to the negative, then recharge in the standard fashion.
2. A boost charge is only for emergencies. It will partially charge
the battery at a high rate and in a short time.
When using a boost-charged battery, it is necessary to recharge
the battery as early as possible.
Failure to do this will shorten the battery's service life.
3. The battery is charge if the indicator display turns green from
black.
4. When exchanging an old battery for a new one, use battery of
equal specification shown in table.

Directions for Storage
1. When shutting down the tractor for long periods of time, remove
the battery from the tractor, store the battery in a well ventilated
placed where it is not exposed to direct sunlight.
2. Since the battery self-discharges by approx. 0.5 % per day even
in storage, it must be once every two months in cold season.
3. When storing the battery mounted on the tractor, disconnect the
ground cable from the battery's negative terminal post.
