XS Power D6500 XS Series 12V 3,900 Amp AGM High Output Battery

The D6500 comes in a faded navy blue body with a white top. This style is used for most batteries sold by XS Power, with a decal that is meant to appeal to young adults.

This XS Power battery is an Absorbent Glass Mat (AGM) battery, designed to seal liquids and prevent spills and leaks. There are no external vents to be found in this battery, making it safe to place in nearly any battery compartment.

You can use this battery either to replace your primary battery or as a supplement. So if you aren’t looking to replace your current battery and just desire to add a little more power, the D6500 can allow you to do this.

The D6500 is highly resistant to forces of nature like harsh weather as well as its own wear and tear. It vibrates minimally, making it capable of lasting a very long time.

As for how it fares while working in your car, it has a high output, making it go seamlessly with any affordable car engine.

The caveat to these batteries is that they are more on the expensive side. With excess output comes high prices, so XS Power considers their batteries to be premium products.

Optima Batteries 8040-218 D35 YellowTop

Optima has its own family of batteries, with different sizes and classes determined by the color of the battery’s top. There are red and blue-topped batteries from Optima, but the model that compares mostly to our XS Power battery of choice is a YellowTop.

The D35 features excellent reserve capacity, promising more than one hour of top-notch performance. It is considered a great battery for cars, old and new.

This battery features a cylinder design that is more than just for show; This battery is designed with SpiralCell technology, which is unique to Optima’s batteries. In a way, this battery has been constructed like a work of art. Each cylinder comes with AGM separators, cast cell connectors and tight, razor-thin compression. All of this makes the battery a safe and spill-proof product.

This battery comes with a three-year warranty, which provides enough time to make sure that it works as intended.

However, the quality of this battery will degrade over time based on the model you choose, which, unfortunately, the warranty will not cover. If your battery dies and it is beyond your control, you will need to buy a new one, unfortunately.

Both the XS Power D6500 and the Optima D35 YellowTop are high-performance batteries. They both are weather and vibration-resistant, they both do a good job preventing leaks and spills and they work great in any car one might own.

The D6500 produces more cold cranking amps and produces better sound quality in car radios than the D35 YellowTop.

The D35 YellowTop can be used as a starter battery, is more affordable and has a longer warranty period than the D6500.

You want the word to be spelled out the same in every instance.

Conclusion

Both XS Power and Optima make their own unique batteries, and while they both come with exciting features and adequate power, the D6500 from XS Power is generally more trustworthy.

The XS Power D6500 comes with an explosive rate of output, and while the D35 from Optima is also quite impressive, we are just uncertain how long it would continue to stay impressive. Despite the D35’s complex construction and efforts made to keep it running for a long time, it just isn’t meant to be a battery that people can use in their car, long-term. Optima’s three-year warranty is nice, but it just isn’t enough to cover the potential issues.
