You can Select Your Vehicle to check if BXT-65-850 fits your vehicle.

To disconnect the battery, start by disconnecting both cables from the battery terminals. It is important to use a battery terminal puller if necessary and always disconnect the negative cable first and hook it up last to avoid shorting the battery. Next, loosen the two battery hold-down clamp nuts to disengage the hold-down legs from the battery tray and remove the hold-down clamp as an assembly. Lift out the battery, using special straps or clamps if available to make the process easier. To install the battery, simply reverse the removal steps. Ensure that the battery cables and battery posts are free of corrosion and clean or replace them if necessary.

To begin work on the vehicle, turn off the engine and all accessories and remove the cable from the negative terminal. Sealed batteries do not require a check of the electrolyte or adding water. In batteries that need maintenance, ensure there is enough distilled water in each cell by inspecting its level of electrolyte. Investigate damage to battery condition, cable clamp, and positive terminal. Apply petroleum jelly or grease on top and tighten hold-down clamp bolt to prevent corrosion. Apply primer and paint to damaged metal parts then clean off corrosion with baking soda solution and water. If you keep the battery in a vehicle for charging purposes, remove cables. A good rating of a slow charger does not exceed 3 amperes. Over the twelve to sixteen-hour process of charging, lead covers should be removed from vent caps, connect charger leads onto battery posts while watching out for overheating.

To disconnect the battery, first remove both cables, starting with the ground cable to avoid shorting. Remember, the vehicle may need to be driven 10 miles after reconnection for smooth operation. Next, remove the bolt and wedge to lift out the heavy battery, using lifting straps if needed. If necessary, remove the battery tray bolts for component access. Reinstallation is the reverse of removal.

In order to jump start the Booster battery in your vehicle, check the front.

Disconnect both cables from the battery terminals. This can be done by removing the cable from a battery post with a wrench. Sometimes special battery pliers are required for this procedure if corrosion has caused deterioration of the nut hex. Always remove the ground cable first and hook it up last. If equipped, remove the heat shield from the top of the battery. Remove the bolt and wedge from the battery tray. This involves removing the bolt and the battery hold down clamp which secures the base of the battery to the battery tray. Lift out the battery, but be careful as it's heavy. Special lifting straps that attach to the battery posts are available at auto parts stores. Lifting and moving the battery is much easier if you use one. If necessary for access to other components, remove the bolts that secure the battery tray. On 1995 and later models, the battery tray is mounted on the driver's side of the vehicle and is fastened by three retaining bolts. On 1994 and earlier models, the battery tray is mounted on the passenger side of the vehicle and is fastened by four retaining bolts, two upper and two lower retaining bolts. Installation is the reverse of removal.

Inspect the positive terminal, cable clamp, and external battery condition for damage, such as a cracked case.

It is recommended to use a one or two-amp battery charger for slow-rate charging.

Disconnecting the negative cable first helps to avoid shorting the battery.

When working with batteries, you should always turn off the engine and accessories and disconnect the negative battery terminal before servicing. Additionally, battery maintenance should be performed in a well-ventilated area since batteries produce flammable hydrogen gas. It is also important to wear protective gear like safety glasses and gloves due to the corrosive sulfuric acid in the battery's electrolyte.

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

When the battery is disconnected, the power that maintains these systems is cut off.

Simply reverse the removal process, connecting the positive cable first and the negative cable last.

Remove the fasteners and take out the battery tray if necessary.

To disconnect the battery for service procedures, loosen the cable end bolt and disconnect the cable from the negative battery terminal. It is also important to isolate the cable end to prevent accidental contact with the battery terminal.

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

Use a battery terminal puller if necessary.

It's important to avoid sparks, smoking, or open flames near the battery because it emits flammable and explosive hydrogen gas.

Lift out the battery using special straps that attach to the battery posts for easier handling.

They should be reserved for emergencies.

To install the battery, simply reverse the removal process.

If needed, you can remove the bolts securing the battery tray for access to other components.

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.

It is important because the battery produces hydrogen gas, which is both flammable and explosive, and the electrolyte contains poisonous and corrosive sulfuric acid.

When charging a battery, higher amperage chargers should not exceed 1/10th of the battery's amp/hour rating to avoid damage.
