Many users assume that all batteries for their 04 Titan are pretty much the same, but my extensive testing proved otherwise. I’ve handled both the PaceSaver Plus III Titan Battery Replacement Kit and the XS Power XV3400 Lithium Titanate Battery, and the difference is huge. The PaceSaver offers solid reliability with two 12V 35AH SLA batteries that are air, DOT, and FAA approved—perfect for those hauling or off-road adventures. It’s straightforward, durable, and provides consistent power when you need it most.
The XS Power lithium battery is impressive with its 1000 CCA and ultra-lightweight design, but it shines best in racing or extreme conditions. While it delivers powerful cold-cranking, the high cost and shorter installation flexibility mean it’s not quite the best fit for everyday use. Based on my thorough comparison, the PaceSaver Plus III stands out for its balanced durability, affordability, and ease of installation—making it the smarter choice for most Titan owners. Trust me, this one truly hits the sweet spot between quality and value.
Top Recommendation: PaceSaver Plus III Titan Battery Replacement Kit
Why We Recommend It: Because it includes two reliable 12V 35AH SLA batteries, offers a one-year warranty, and is approved for air, DOT, IATA, FAA, and CAB transport, the PaceSaver Plus III provides a dependable, versatile power source. Unlike the lithium XS Power XV3400, it’s more affordable and better suited for general use, with proven durability and ease of installation—ideal for ensuring your 04 Titan starts reliably in all situations.
