Photo 1: Remove the case screws
Pry off the plastic and rubber trim pieces to access the
screw holes. Plunge a 6-in. driver bit deep into the holes to
remove the screws. Keep track of their locations so you
can put them back into place.

Photo 2: Swap out the battery
Remove the cables from the negative battery terminal,
noting the locations of the lock washers and the placement
of any other wires. Do the same at the positive terminal.
Then swap in the new battery, making sure the positive and
negative terminals are near the correct cables.
Using a battery-powered booster pack is the safest way to jump start
a car because it eliminates the possibility of sparks and
alternator damage. But the lead-acid battery inside the pack
doesn’t last forever. When the battery inside your booster pack
stops working, you can rebuild it yourself for a fraction of the
price of a new one.
You’ll need a 6-in. Phillips or star bit, a drill and a 1/4-in.-drive
socket or nut driver set. Once you open the case, remove the
battery and match it up at a local auto parts or battery store. If
you want to order a replacement online, measure the battery’s
overall size and note the terminal style and amp-hour rating. Our
replacement battery cost about $35 online.
To replace your battery, start by removing the decorative trim
pieces and screws (Photo 1). Then separate the case and swap
the batteries (Photo 2). Reassemble the case and charge the
battery until the charge light turns green. The booster pack can now be used for jump starting a dead car battery.
