7. Be careful not to drop a metal object on the battery

or allow a metal tool to simultaneously touch the positive

and negative cable ends or battery terminals. It might

spark or short-circuit the battery or other electrical parts

and cause an explosion.

8. Remove personal metal items such as rings, bracelets,

necklaces, and watches when working with a lead-

acid battery. A lead-acid battery produces a short circuit

current high enough to weld a ring or other similar

objects to metal, causing a severe burn.

If you do not know how to safely remove and install higher

amperage batteries, have this task performed by a qualified

service technician.
Follow these steps to replace the battery:
1. Place Portable Power 250 upright and on a stable and

level surface. Unscrew the 4 fasteners that hold the

Battery Cover on the black of Portable Power 250 and

remove the cover. Place the fasteners in the cover for

safe keeping.

2. With Portable Power 250 still upright, slide the battery

out. Using a screw driver and small adjustable wrench,

remove the nut and bolt that hold the internal positive

and negative cables to their respective battery terminals.

Note how the nut, bolt, and washers attach the internal

cable to the old battery terminal and make certain they are

positioned in the same order when connecting the cables

to the terminals of the new battery.

IMPORTANT: The location of the positive and negative

terminals vary from one battery manufacturer to another.

Check your replacement battery polarity carefully before

connecting the battery cables.

3. After removing the old battery, position the new battery

close to the back of Portable Power 250. Make certain the

positive battery terminal is next to the red (+) internal

cable and the negative terminal is next to the black (-)

internal cable.

4. Securely fasten the bolt, washer, and nut that holds the red

positive cable to the positive battery terminal and the

black negative cable to the negative battery terminal. Do

not over tighten the nut and bolt. Make sure cable

polarity is correct. Reverse polarity will damage the unit

and could cause serious injury.
