WARNING! Battery posts, terminals, and related accessories contain lead and lead compounds.
Wash hands after handling.
How can I get maximum range or distance per charge?
Rarely will you have ideal driving conditionssmooth, flat, hard driving surfaces with no wind or curves. Often, you
will face hills, pavement cracks, uneven and loosely packed surfaces, curves, and wind, all of which affect the
distance or running time per battery charge. Below are a few suggestions for obtaining the maximum range per
battery charge.
n
Always fully charge your Boxsters batteries prior to daily use.
n
Maintain
30-35
psi (pounds per square inch) in each tyre.
n
Plan your route ahead to avoid as many hills, cracked, broken, or soft surfaces as possible.
n
Limit your baggage weight to essential items.
n
Try to maintain an even speed while your Boxster is in motion.
n
Avoid stop-and-go driving.
What type and size of battery should I use?
We recommend deep-cycle batteries that are sealed and maintenance free. Both sealed lead-acid and gel cell are
deep-cycle batteries that are similar in performance. Do not use wet-cell batteries, which have removable caps.
CAUTION! Do not remove the caps from sealed batteries. Water cannot be added to sealed
batteries. Cap removal voids the battery warranty and may cause damage to the batteries and to
your Boxster.
Use these specifications to reorder deep-cycle batteries:
Type:
Deep-cycle (sealed lead-acid or gel cell)
Size:
U-1 - (32 AH) 40 AH or NF-22 (45 AH, 55 AH)
Voltage:
12 volts each
Amperage:
32 AH, 40 AH, 45 AH, or 55 AH
To change a battery in your Boxster:
1. Remove the seat and the rear shroud. See VIII. Disassembly and Assembly.
2. Disconnect the battery tie-down straps (if so equipped).
3. Disconnect the battery cables from the electronic controller module.
4. Disconnect the battery cables from the battery terminals.
5. Remove the old battery.
6. Place a new battery in the battery well.
7. Connect the red battery cable to the positive (+) battery terminal.
8. Connect the black battery cable to the negative (-) battery terminal.
9. Reconnect the battery cables to the electronic controller module.
10. Reconnect the battery tie-down straps (if so equipped).
11. Reinstall the rear shroud and the seat.
Why do my new batteries seem weak?
Deep-cycle batteries employ a different chemical technology than that used in car batteries, nickel-cadmium batteries
(nicads), and other common battery types. Deep-cycle batteries are specifically designed to provide power, drain
down their charge, and then accept a relatively quick recharge.
