Sensor Type	Battery current sensor
Replacement Part Number	38920-TR0-A02
Compatible Models	2012-2015 Civic/CR-V 2.4L (per listing)
Warranty	12 months

What We Found

This YuanchiNB component is a battery current sensor replacement, not a direct starting battery or key fob battery. It targets specific OE part numbers and supports 2012-2015 Honda Civic and CR-V models with a 2.4L engine, replacing number 38920-TR0-A02.

The sensor’s purpose centers on monitoring current into and out of the battery to assess health, detect anomalies, and prevent failures. It also cites real-time electrical monitoring and OEM design made to original factory specifications.

Installation guidance outlines disconnecting the negative cable, removing bolts, swapping the sensor, and reconnecting for sensing stability. A 12-month warranty appears in the listing, which improves buyer confidence even without rating data.

Installation instructions include disconnecting the negative terminal, removing the existing ground cable, swapping the sensor, and reconnecting securely. A 1-year warranty and support response are stated, which provides risk reduction for an electronic repair. This product is best viewed as a targeted diagnostic fix rather than a general battery replacement.

Who It’s For

This sensor fits CR-V owners receiving battery management or charging-related warnings tied to the negative cable sensor. It suits drivers who can confirm the exact OE number and vehicle range listed by the seller.

Installation suits confident DIYers or mechanics since it requires safe handling of the negative terminal and secure cable reattachment. It can help when battery performance appears inconsistent due to sensor input errors. For simple no-crank issues, replacing the sensor may not solve the problem, so proper diagnosis matters.

What to Look For Before Buying

Selecting the right “Honda CR-V battery” starts with identifying which battery needs replacement. A key fob uses a specific coin-cell type, while the vehicle uses a starting battery defined by group size, CCA, and battery technology.

Next, confirm compatibility using the fitment tools and battery numbers shown on the remote or label on the old battery. Then compare warranty length, design features like AGM sealing, and practical install requirements.

Check Confirm key fob battery type and remote style

Look for the battery number printed on the key fob before buying CR1616 or CR1620 or CR2032 replacements. Use the fitment guide shown in product images to match smart fobs versus key-exposed fobs. If the listing excludes your remote style, skip it to avoid wasted purchases.

Choose kits that include videos or opening tools when the remote case feels tight.

Value Match starting battery specs to climate and driving habits

For vehicle batteries, prioritize CCA for cold starts and reserve capacity for accessory use. AGM batteries tend to perform well with vibration resistance and sealed maintenance, which suits stop-and-go driving. Flooded batteries can work well in hot-to-moderate climates and usually cost less.

Always confirm group size fit so the battery physically mounts correctly in the CR-V tray.

Rating Use warranty and build claims when ratings are limited

When Amazon rating signals are missing, lean on warranty length and clear technical specifications. AGM offerings should highlight safety standards like CE or ISO facility testing. Key fob sellers should provide fitment proof and installation guidance to reduce failure risk from wrong battery selection.

Real-world longevity still matters, so search for similar verified fitments after purchase.

Verify Differentiate battery replacement from sensor repairs

Some listings sell battery current sensors or negative battery cable sensors, which address monitoring and charging logic. These parts suit diagnostic symptoms like charging warnings, not a simple no-crank battery. Confirm OE part numbers and vehicle year range before ordering.

If the CR-V will not start, test the starting battery first instead of replacing sensors.

Frequently Asked Questions

Which battery type does a Honda CR-V key fob use: CR2032 or CR1616 or CR1620?

The correct coin-cell depends on the exact remote head and model year. Check the battery number printed on the back of the existing fob first. Then compare that number with the product’s compatibility list and fitment images.

If the listing mentions excluded key styles, verify your remote matches the smart-fob category.

Do CR-V key fob battery replacements require programming?

Most CR-V key fob battery swaps do not require programming. Several listings specify that remote reprogramming is not required after replacing CR2032 or similar cells. Still, it helps to follow included video instructions and reinsert the battery with correct polarity.

If the remote fails after replacement, the battery may be wrong or the fob contacts may need cleaning.

When should a CR-V current sensor or negative battery cable sensor be replaced?

Sensors usually replace diagnostic components related to the battery management system. Replace them when warnings or charging behavior point to sensing faults. Confirm the OE part number and compatibility by year and model before buying. A sensor replacement will not fix a weak starter battery that fails to crank.

AGM or flooded battery: which works better for a Honda CR-V?

AGM batteries are sealed and designed for strong cranking, vibration resistance, and low mess service. Flooded batteries are conventional and can deliver dependable performance in hot to moderate climates. The best choice depends on your CR-V requirements for group size and electrical system behavior.

If stop/start performance and durability matter, AGM often fits better.

How can compatibility be verified for CR-V starting batteries?

Use the group size and CCA ratings required by the vehicle’s battery tray and wiring. Many listings suggest confirming with an Amazon Confirmed Fit Tool. Also compare the physical size of the old battery terminals and hold-down configuration.

If fitment guidance is unclear, measure the old battery and match dimensions before ordering.

🎯 Final Verdict

Choose the Mighty Max AGM MM-H5 for the most dependable Honda CR-V starting performance. Its sealed AGM build and 680 CCA output target strong cranking and resilience in harsh conditions. For a different problem, use KKNCO’s CR2032 smart-fob pack to restore keyless access quickly without programming.

Confirm compatibility with the fitment guide or battery number, then install carefully using the provided instructions.
