Extending battery life

• Make sure replacement battery equals or exceeds original equipment cranking and reserve capacity specifications.
• remove vent caps and check water level, if water is low, add distilled water to just above the plates.
• replace worn or damaged battery cables
• install anti-corrosion washer
• keep battery post clean with post brush
• use vehicles original equipment battery hold-down.

Safety Notes & Precautions:

When installing a new car battery always wear proper eye, face and hand protection

Install positive cable to positive terminal, then negative cable to negative terminal.

Tighten connection; do not hammer.

Make sure that clamps and connections do not touch metal objects.

How to charge a 8 volt battery

• Use a 12-Volt battery charger
• Set Charger to no more than 10 amps
• monitor the battery at all times as it is being charged.
• When the battery reaches 9.6 Volts, continue to charge for about 15 to 20 minutes.
• Battery is fully charged
  

  8 Volt Battery

Constant-Voltage Method (Recommended Method)

The AGM battery is sensitive to high voltage charging (Above 14.4 Volts). The recommendation is to use a 6 to 12 amp, 12-volt automatic charger set at the regular setting. If you use a non-automatic charger, you need to monitor the voltage so it does not exceed 14.4 volts and/or 12 amps at any time during recharge. This battery needs recharging only if the open-circuit voltage (O.C.V.) is below 12.5 volts.

(DO NOT OVERCHARGE)

Charging Your Battery

The room or compartment in which the battery is being charged should be well ventilated. Do not put a battery on charge unless you are wearing safety goggles and a face shield. It must be assumed that explosive mixtures of hydrogen gas are present within the battery cells at all times. Even a battery standing idle generates small quantities of hydrogen due to the self-discharge action. This gas collects in the cells and can be exploded by a torch, match flame, lighted cigarette, sparks from loose connections or metal tools making contact between the terminals and the ungrounded terminal and adjacent metal parts which are grounded.

Since vent cap designs having flame barrier features are not easily distinguished from other style vent caps, it is recommended that vent caps be left on the battery during charging. As a further precaution, place a wet cloth over the battery vent caps. sense flame arresters are used in most modern vent cap designs to reduce the possibility of the battery being exploded by an external spark, this safety feature could be bypassed by removal of the vent caps. Whether such vent caps are present or not, always shield eyes when working around the battery and follow the precautions covered here.

Do not charge a battery unless you are thoroughly familiar with the step-by-step procedure to use. Follow the manufacturer’s instructions on the charger. If the instructions are no longer legible and you do not have the literature containing the instructions, obtain them from the manufacturer of the charger. Never use a charger without instructions.

Turn the charge rate switch and timer to the “OFF” position before connecting the leads to the battery. Next, connect the charger leads to the battery terminals, red positive(+) lead to positive terminal and black negative (-) lead to negative terminal. If the battery is in the car, connect the negative lead to the engine block if the car has a negative ground(negative battery terminal is connected to the ground). Connect the positive lead to ground if the car has a “positive ground”(now rarely occurs). “Rock” the charger lead clamps to make certain a good connection has been made. Set the electric timer to the desired charging time. Now, turn on the charger and slowly increase the charging rate until the desired ampere value is reached. Do not charge in the red zone. If smoke or dense vapor comes from the battery, shut off the charger and reject the battery. If violent gassing or spewing of electrolyte occurs, reduce or temporarily halt charging.

Never touch the charger leads when the charger is “ON”. This could break a connection at the battery terminal, creating a spark which could ignite the explosive gases in the battery. Never break a “LIVE” circuit at the battery terminals for the same reason. Always turn the charger “OFF” before removing a charger lead from the battery.

When charging or testing a side terminal battery out of a vehicle, always use the side terminal charging and testing posts which have been designed for this purpose.
