Ford BXT-65-850 Battery

When performing work on or in proximity to the battery, take extra care not to inadvertently connect any tool between the negative and positive terminals, or make ground, as this causes shorting and possible severe electric shock. Fire and other sources of ignition such as smoking and spark should not come in contact with battery because has explosive gases. It is mandatory to hold on the battery using a hold-down device in order to avoid its movement and consequently acids leakage and corrosion. Daily or at least weekly visual check for cracks, leakage and overall corrosion is required and damaged batteries need to be replaced as quickly as possible. Before removing a battery, the negative terminal should be disconnected and then the positive one, next, the hold-down device should be loosened and then the battery should be removed. As the battery is removed, ensure that the battery tray is clean as well as free from rust and clear it if necessary. In installation, tighten the hold-down device but do not over tighten it as you connect the positive cable before the negative one. Non-sealed batteries need routine examination of the electrolyte level and replenishing with distilled water if needed, while a sealed battery needs to be checked with the assistance of the hydrometer that is installed on it. There is also need to ensure that battery terminal and cables are free from any form of corrosion and cleaning should be done at least once a year. In a case where the battery is not frequently used then removing the negative terminal during the period of storage is recommended. It is recommended for the electrolyte level to be controlled once a month and the addition of distilled water is necessary in freezing weather. Specific gravity tests can show battery charge and also reveal if there is swelling and if the cells are very high or very low, then they should be replaced. Battery terminals and cable clamps need to be cleaned at least once a year, the electrical connection must be good and dielectric grease can be also used to retard corrosion. In charging the battery, this should be done slowly in order not to over heat the battery and when the battery is being replaced, an amperage rating of the battery must be equivalent or higher than the original battery, to allow for the increased electrical resistance in the battery.

To disconnect the battery, start by disconnecting both cables from the battery terminals. Remember to always disconnect the negative cable first and hook it up last to avoid shorting the battery. Next, locate the battery hold-down clamp on top of the battery and remove the bolt and nut to detach the clamp. Once the clamp is removed, lift out the battery using special straps that attach to the battery posts for easier handling. Installation is the reverse of removal.

Vehicles require constant battery power for systems like control unit memory and continuous operation. Disconnecting the battery can disrupt these systems and potentially trigger power door locks. To avoid issues, use a memory-saver, a device plugged into the cigarette lighter and connected to an auxiliary battery, maintaining codes and power for essential circuits. When disconnecting the battery, detach the cable from the negative terminal and isolate it.

Ensure that the battery cables and battery posts are free of corrosion.

Slow-rate charging with a one or two-amp battery charger.

Routine preventive maintenance is important for maintaining your vehicle's battery because it ensures reliable starts.

Start by removing both cables from the battery terminals. Use a wrench or battery pliers if necessary.

Avoid using chargers rated more than 1/10th the amp/hour rating of the battery.

The ground cable should be removed first and hooked up last.

The battery drain test indicates whether there's a constant drain on the vehicle's electrical system that can cause the battery to discharge.

If the electrolyte level is low, add distilled water and install cell caps, taking care not to overfill.

Always disconnect the cable from the negative battery terminal FIRST and hook it up LAST to avoid shorting the battery with the tool being used to loosen the cable clamps.

The battery produces hydrogen gas, which is both flammable and explosive. Creating a spark, smoking, or lighting a match around the battery can lead to dangerous situations.

Next, locate the battery hold-down clamp on top of the battery.

When examining the battery's external condition, you should check for damage, corrosion, loose connections, cracks, and the condition of hold-down clamps.
