INDICATIONS OF A FULLY CHARGED BATTERY
CHARGE PERIOD
1. Before charging any battery, make sure the electrolyte (battery fluid) in each cell is at correct level. This is not required on
maintenance free batteries. Read instructions on battery.
2. Set switches and or timers to Off, if the position is available. If no Off position is on your charger, set in the lowest charge rate
featured usually, 2 amp.
3. If the battery is being charged inside the vehicle, use connection procedures outlined in Section E. Should the battery be removed
from the vehicle, follow the instructions in Section D (step 6) and Section F. Plug the power cord into the AC outlet.
4. Set the power switch from Off (or the lowest charge rate) to the desired charge position. NOTE: This charger is a MANUAL type
charger and the charging must be monitored closely to prevent overcharging of the battery.
The approximate time required to bring a battery to a full charge state depends upon the number of ampere hours (AH’s!
depleted from the battery. AH’s are determined by multiplying the number of hours time the number of amps supplied by the
battery to the load For example- If a load was connected to battery which drew 7 amperes for a period of five hours, the battery
will have supplied 35 AH. The approximate recharge time would be calculated by dividing 35 AH depleted from the battery, by
the ampere charge rate of the charger .To allow for tapering of the charge rate add 25% to the charge time.
A hydrometer reading of the specific gravity of the electrolyte (fluid) of a battery in good condition should be between 1.25 and 1.285.
When a battery reaches 80-85% of full charge, bubbles will appear on the surface of the fluid As the battery nears full charge, bubbling
will become more vigorous.
When the meter reaches about half the charge rate, see Meter Function, Section G.
1. Connect the charger to the battery following instructions given in Section K.
2. Set charger to Off position, (on SE-1052 set at the 2 amp position).
3. Plug power cord into AC outlet, then move switch from Off to Engine Start. On SE-1052 move from 2 amp to Engine Start.
4. During extremely cold weather, or if the battery is fairly exhausted, charge the battery for a few minutes before you attempt the
Engine Start.
5. Crank the engine by turning the ignition key.
6. If the engine fails to start, let the battery charge for another/few minutes then, try the engine start again.
Never place the charger directly above battery being charged, gases from battery could damage the charger.
Never allow the battery acid to drip on charger when reading specific gravity or filling battery.
Do Not operate the charger in a closed in area or restrict ventilation in any way. Keep off from carpets, seats, etc.
Do Not set the battery on top of the charger.
