A dead battery in a 2009 Nissan Murano is a sudden stop to your day. You need a replacement that cranks your Murano’s V6 reliably, fits the tight Group 49 (H8 size) battery tray, and lasts more than a year without failing.
I’m Min Islam — the founder and writer behind Trending Car. This guide is built by comparing the manufacturers’ published specifications and the patterns across verified customer reviews, so you get each pick’s real strengths and trade-offs instead of marketing spin.
After looking at the specs and what owners actually report, three batteries stand out for the 09 nissan murano battery. Each offers a different balance of durability, warranty length, and starting power.
Our Picks at a Glance
How To Choose The Best 09 Nissan Murano Battery
The 2009 Nissan Murano needs a Group 49 battery (also called H8) with top-post terminals (the posts on top). This is non-negotiable because a different group size will not fit the hold-down bracket. Once you have the right size, your main choice is between a conventional flooded battery and an AGM battery. The decision depends on whether you drive your Murano every day or let it sit for days.
AGM vs Flooded: Which Should Your Murano Get?
An AGM battery (Absorbed Glass Mat) uses fiberglass mats to hold the electrolyte (the acid) instead of letting it slosh as liquid. This makes it spill-proof and very resistant to the vibration your Nissan Murano creates on rough pavement. AGM batteries also handle repeated discharge-recharge cycles far better than a flooded battery. That helps if you run accessories with the engine off. The trade-off is a higher upfront price.
Cold Cranking Amps (CCA) Matter for Real Starts
CCA (Cold Cranking Amps) is the number of amps a battery can deliver at 0°F for 30 seconds while keeping voltage above 7.2 volts. Your Murano’s V6 engine needs a high CCA rating. A battery with higher CCA cranks the engine faster and more reliably in winter, and gives you a safety margin as the battery ages.
Warranty Is Your Safety Net
A 36-month free replacement warranty is standard among premium batteries — it covers the three-year window when most failures happen. If the battery dies within that period, you get a replacement at no cost.

In‑Depth Reviews
1. Interstate Batteries MTX-49/H8
Our pick — 4.5★ from 400+ verified ratings; the strongest balance of quality and price.
The heaviest battery in this group, with dense lead plates for serious, reliable cranking power.
This Interstate MTX-49/H8 weighs 59 pounds — a full 68% heavier than the ACDelco Gold 49AGM at 35.2 pounds. That extra weight comes from more lead inside the AGM construction, which directly translates to longer life. Interstate claims the MTX delivers 2x the service life of a standard AGM and 3x the life of a flooded battery. For your Murano, that means you get confident cold starts and a battery that keeps working year after year.
The 900 CCA rating is the highest in this comparison. It gives your Murano’s V6 a fast, strong crank even in deep winter. One buyer reports this Interstate “saved my brothers old suburban from being junked in the cold snows of Indiana. started right up.” That real-world reliability is what you want when a dead battery means a tow. The MTX is spill-proof, maintenance-free, and has a 3-year performance warranty. It holds a 4.5-star average from 409 ratings — the highest rating here — though the budget ACDelco 49AGM has more total reviews at 721.
Crank Power You Feel
- 59-pound weight means dense lead plates for outstanding longevity
- 900 CCA gives instant, reliable starts even in freezing conditions
- Spill-proof and vibration-resistant AGM construction built for an SUV
- 3-year performance warranty covers the most common failure period
The Real Trade-Off
- Heavy — lifting it into the Murano’s tray takes some muscle
- Higher upfront cost than a conventional flooded or silver-calcium battery
- A few owners note the manufacture date could already be a year old on delivery
Reach for this if: you want the single most durable battery with the highest cold-cranking power for your Murano — and you plan to keep the car for several more years.
Think twice if: a 59-pound battery feels too heavy for you to install alone, or if a silver-calcium battery at a lower price better fits your budget.
2. ACDelco Gold 49AGM (88864539)
A silver-calcium battery that delivers big on value — it is 24 lbs lighter than the Interstate and costs less.
This ACDelco Gold 49AGM uses a silver-calcium stamped alloy design instead of a pure AGM. Silver-calcium means the battery plates use a calcium alloy that improves electrical conductivity and resists corrosion. The case is precision-ribbed and 100% pressure-tested to avoid future leaks. It holds a 4.1-star average from 721 reviews — the highest review count among these three picks. That tells you many Murano and other vehicle owners have trusted this battery.
Fit is the top-praised aspect, with 61 owners noting it fits their vehicle perfectly. One Mercedes-Benz owner called it “30% the price of the battery that the Mercedes Benz dealership was trying to sell me” and said “it’s been several months and I have had no issues and the 3 year warranty is the cherry on top.” At 35.2 pounds, it is far easier to lift into your Murano’s tray than the 59-pound Interstate. Customers name battery quality (72 mentions) as the most-praised trait. It also comes with a 36-month free replacement warranty.
Where It Shines
- Lighter at 35.2 lbs — much easier for one person to install than the Interstate at 59 lbs
- Silver-calcium alloy improves cycle life and resists corrosion
- 36-month free replacement warranty offers a full safety net for three years
- Massive buyer trust with 721 ratings and a 4.1-star average
The Honest Caveat
- Battery life is the most-discussed negative aspect (59 mentions) — some buyers report failure within months, though most are satisfied
- Slow shipping mentioned across multiple reviews as a recurring delay
- A small number of buyers received a dead battery on arrival and needed a replacement
Best for: the Murano owner who wants a high-quality, dealership-matching battery without paying the dealership mark-up — and who values an easy 35.2-lb installation.
Look elsewhere if: you need maximum CCA for extreme winter conditions, or if you want a heavier AGM construction that is more vibration-resistant.
3. ACDelco Gold 49AGMHR (88866099)
An AGM battery with a high reserve capacity (extra power stored) for Muranos that sit for days.
This ACDelco Gold 49AGMHR uses an AGM construction that gives it better deep-cycle resilience than a standard flooded battery. At 55.6 pounds, it is close to the Interstate’s 59 pounds but has different dimensions — 7.5 inches deep by 13.9 inches wide by 6.9 inches tall. That is deeper (7.5 inches vs 6.9 inches) and shorter (6.9 inches vs 7.5 inches) than the ACDelco 49AGM. The 0.6-inch depth difference matters if your Murano’s tray has specific clearance.
The honest read is more cautious here. While fit gets positive marks (7 mentions), quality (10), reliability (8), and battery life (8) are all rated as MIXED or NEGATIVE by Amazon’s review analysis. Battery life gets the most negative mentions. One owner summarized the risk clearly: “Didn’t even last 2 years. The battery dies if you don’t start your car for a week. I had to jump it every time I want to drive my car.” This suggests the 49AGMHR does not handle being left unused for long stretches. It carries a 4.0-star average from 108 ratings — the lowest score and smallest review pool here.
What Works
- True AGM design for better vibration resistance and spill-proof operation
- High reserve capacity intended for vehicles with heavy accessory loads
- Double 36-month free replacement warranty offers full protection
- Weighs 55.6 lbs — a stout construction with good lead content
The Risk You Should Know
- Multiple owners mention premature failure within two years, especially if the car sits for a week
- 4.0-star average from only 108 ratings is the weakest vote of confidence here
- Battery life is the most-discussed negative aspect, and the quality rating is marked MIXED by Amazon’s review analysis
Suits: the Murano owner who drives daily and wants an AGM battery at a lower price point than the Interstate — and who accepts the 4.0-star rating risk in exchange for the 36-month warranty.
skip it if: your Murano sits unused for a week or more at a time — real owner reports strongly suggest this battery struggles with that pattern.
Understanding the Specs
Group Size 49 (H8) — The Only Fit
A battery’s group size defines its physical length, width, height, and terminal location. The 2009 Nissan Murano requires a Group 49 battery (also called H8 in many catalogs). If you use any other group size, the hold-down bracket will not clamp, the terminals might not reach your cables, or the battery simply will not fit the tray. Always verify group size before buying, because an “almost fits” battery can shift and cause a fire hazard on the road.
AGM vs Silver-Calcium vs Flooded
Flooded batteries are the traditional type with liquid acid sloshing inside. They are cheap but vulnerable to vibration and can leak if tipped. AGM (Absorbed Glass Mat) batteries suspend the acid in fiberglass mats, making them spill-proof, vibration-resistant, and better at handling repeated discharge cycles. Silver-calcium batteries, like the ACDelco Gold 49AGM, use a calcium-alloy grid that improves conductivity and resists corrosion. They offer a good middle ground between price and performance without the full AGM cost.
