Are you replacing the battery in your Harley Davidson FLH Electra Glide Special 1340 and wondering if the Compatible with Harley Davidson FLH Electra Glide Special 1340 1984-2000 Yuasa Battery Already Ready to Use Y50-N18L-A 12V/20AH Batteries for Starter Motorcycles Specifications is the right choice for your ride?
Product snapshot
You want a clear picture of what this battery is before committing. This Yuasa Y50-N18L-A is sold as a replacement that’s specified in the product title for fitment to Harley Davidson FLH Electra Glide Special 1340 models from 1984–2000, rated at 12V and 20Ah, and described as “already ready to use.” The listing emphasizes that the specific model is indicated in the title and that the unit comes complete and ready.
What the product name tells you
You rely on the product name to confirm fitment for your bike. The name explicitly states compatibility with the Electra Glide Special 1340 (1984–2000) and gives the exact Yuasa model number, which helps you match it to your motorcycle’s service manual or the battery bay dimensions.
What “already ready to use” means for you
Seeing “already ready to use” is convenient because it indicates the battery ships pre-charged, so you can install it right away without a long initial charge. That saves you time and lets you get your motorcycle back on the road faster.

How to use the spec table
You can use this table to quickly match the battery to your service manual or to dimensions and terminal orientation on your old battery. Confirm the physical size and terminal polarity before ordering, since motorcycles often have tight clearances.
Fit and compatibility
You need assurance the battery will physically fit and connect correctly. The seller lists this Yuasa model specifically for Harley Davidson FLH Electra Glide Special 1340 models from 1984 through 2000, which indicates the most common fitments for that battery size and terminal arrangement.
Physical fit considerations
Even though the model is listed as compatible, you should compare the length, width, height, and terminal orientation of the Yuasa Y50-N18L-A to your original battery. You’ll also want to confirm any bracket or strap mounting points and whether the battery requires a protective cover or hood for terminals.
Electrical fit considerations
You must match voltage and capacity for reliable starting. This battery’s 12V nominal rating is standard for Harley starter systems from that era. The 20Ah capacity is appropriate for starter duty; you should also make sure the terminal polarity matches your motorcycle’s cables to avoid incorrect connections.
Unboxing and packaging
You want to know what to expect when your battery arrives. The listing calls the battery “complete and ready,” so you should receive a pre-charged unit packaged to protect it in transit.
What should be included
Expect the battery itself, possibly a protective terminal cap or minimal packaging. If the listing mentions additional accessories, those should be stated explicitly; otherwise plan on receiving the battery only and any customary packing materials.
Inspect upon arrival
When the battery arrives, check for physical damage, confirm it’s the right model number (Y50-N18L-A), and verify that the terminal covers are present. If anything looks damaged, don’t install it — contact the seller immediately.
Installation: step-by-step guidance
You want to get the battery into your bike safely and correctly. Follow these steps to minimize risk and ensure proper connection.
Tools and safety
Wear safety glasses and gloves, and keep any open flames or sparks away. You’ll typically need a wrench or ratchet set to remove the hold-down bracket and battery terminals. Have the owner’s manual handy for torque specs and terminal locations.
Installation steps
- Turn off all electronics and remove the key from the ignition to prevent accidental shorts.
- Remove the seat and any covers to access the battery compartment.
- Loosen and disconnect the negative (ground) terminal first, then the positive terminal — this reduces the chance of a short.
- Remove the hold-down bracket and lift out the old battery, noting any straps, spacers, or insulating pads that need to be reinstalled.
- Place the Yuasa Y50-N18L-A into the battery tray in the correct orientation.
- Reattach the hold-down bracket and any brackets or straps, ensuring a snug fit but not overtightened.
- Connect the positive terminal first, then the negative terminal. Tighten the terminal clamps securely.
- Replace any terminal covers and reassemble the seat and other panels.
- Start the motorcycle to verify installation and charging system function.
Post-installation checks
After installation, make sure the engine starts quickly and that the charging system is operating (battery voltage should be above resting voltage when the engine is running). If the bike struggles to start or electrical issues appear, double-check connections and polarity.
Performance and starting ability
You want a battery that reliably turns over the starter and gives consistent performance. This Yuasa model’s 12V/20Ah rating is geared toward starter applications and should supply the burst current your Harley needs to crank the 1340cc engine.
Cold cranking considerations
Cold starts demand higher current. While the listing doesn’t specify cold cranking amps (CCA), a properly maintained 12V starter battery marketed for motorcycles typically handles the short high-current draws required to turn a V-twin starter motor. If you live in very cold climates, consider monitoring starting performance and having a backup charger available if starts become sluggish.
On-road reliability
You should expect dependable starts and steady electrical supply for lights, ignition, and accessories under normal riding conditions. The key is ensuring the battery is charged and that your motorcycle’s charging system (stator/rectifier) is functioning properly.
Charging and maintenance
You want to keep the battery in good shape for as long as possible. The listing’s “already ready to use” note suggests it’s shipped charged, but you’ll still want to follow best practices for charging and maintenance.
Routine charging advice
If you ride often and short rides keep the battery at or near full charge, minimal maintenance is needed. If you store the bike or ride infrequently, use a smart, motorcycle-compatible battery tender to maintain charge without overcharging. Avoid cheap chargers that can overheat motorcycle batteries.
Maintenance tips
- Keep terminals clean and lightly greased with dielectric grease to prevent corrosion.
- Check hold-downs to ensure the battery is secure (vibration shortens life).
- Disconnect and store the battery properly if the bike is idle for long periods, or use a quality maintainer.
Lifespan and durability
You want a battery that lasts several seasons. Actual lifespan varies by usage, climate, and charging practices, but a well-maintained motorcycle starter battery commonly lasts between 2 and 5 years.
Factors that affect lifespan
Frequent deep discharges, excessive vibration, poor charging system function, and extreme temperatures all shorten battery life. Keeping your charging system healthy and avoiding long storage without a tender will maximize longevity.
What to expect from this Yuasa model
Yuasa is a well-known brand in the motorcycle battery market. If this Y50-N18L-A follows their usual manufacturing quality, you should expect reasonable durability and consistent performance versus cheaper, off-brand alternatives.
Cold-weather and hot-weather performance
You want to know if extreme temperatures will impact starts or battery health. Temperature affects chemical performance and capacity.
Cold-weather notes
Cold reduces available capacity and makes starting harder, so you’ll rely more on the battery’s ability to deliver short bursts of current. If you ride in freezing conditions frequently, keep the battery warm when possible or store it in a warm place when not in use.
Hot-weather notes
High heat can accelerate battery degradation. Make sure the battery isn’t exposed to prolonged direct sunlight or heat sources and confirm the battery fits correctly without contact against hot engine or exhaust components.
Safety and handling
You want to handle and dispose of the battery safely. Follow standard precautions for lead-acid batteries and any instructions from the seller.
Safe handling
Wear protective gloves and glasses when handling, keep sparks/flames away, and always remove the negative cable first when disconnecting. If you notice leakage, bulging, or a cracked case, don’t use the battery and contact the seller or a service provider.
Disposal and recycling
Lead-acid batteries are widely recyclable. Don’t dispose of the battery in regular trash. Take old batteries to a recycling facility, retailer, or motorcycle shop that accepts battery returns.
