What’s included in the box
You’ll want to know what arrives with the battery so you’re not caught without the small items required for installation. Manufacturers or sellers sometimes include extras that make the swap easier.
The package typically contains the Skyrich HJTX14H-FP lithium battery itself and may include a pair of work gloves as a complimentary item. Depending on the seller, you might also receive foam padding, simple instructions, a warranty card, or plastic spacers; confirm what’s included before you buy to avoid missing connectors or mounting hardware.
Compatibility and fitment details
You’ll want absolute clarity on fitment so you don’t end up with a battery that physically doesn’t mount or an electrical fit that requires modifications. This battery listing calls out the Aprilia RSV 4 RR (RKL00/KE000) 1000 for model years 2015–2021, and the listed dimensions suggest it’s intended to sit where the OEM battery lives.
Double-check three things on your bike: the internal dimensions of the battery compartment, terminal type and location (positive/negative orientation), and the battery hold-down or strap style. The “POS. SX” reference translates as left-side placement orientation. If your RSV 4 RR has the battery mounted in a standard position, you should be able to fit this unit; if previous owners modified the battery box, remeasure before ordering.
Physical dimensions and how they matter
The 150 x 87 x 93 mm measurement set is small compared with many conventional batteries, which works to your advantage when you want a snug, secure mount without bulky filler. You should measure the length, width, and height of your battery tray and allow a few millimeters clearance for wiring and vibration damping.
Because this battery is lighter, you’ll also see weight savings affecting handling slightly—less mass high on the bike can make the front end feel a touch livelier. Be careful that the battery retains the same terminal polarity and orientation; some lithium packs change terminal placement compared with the OEM and require adapter leads or a different mounting method.
Electrical fitment and terminal considerations
Polarity and terminal type are critical. You must confirm that the positive and negative posts are positioned where your bike’s wiring expects them to be. If the terminals are reversed or in a different spot, you’ll need adapter cables or custom connectors to avoid stress on the wiring harness.
Additionally, your RSV 4 RR’s charging system must be compatible with lithium-ion chemistry. While many modern motorcycle regulators/rectifiers work fine, some older or aftermarket charging systems produce voltage spikes that can shorten lithium battery life if not managed. Check charging voltage specs and, if necessary, consider a voltage stabilizer or a dedicated lithium-compatible regulator.
Performance characteristics and riding impressions
You’ll notice several performance differences right away when switching from a conventional lead-acid battery to a Skyrich lithium unit. These differences affect starting, throttle response in some cases, and even a small change in weight distribution.
Lithium batteries like the HJTX14H-FP typically provide higher cranking amps per weight and maintain higher voltage under load, which helps with consistent and quick engine starts—great if your RSV 4 RR spends time idle between runs. You’ll generally get better cold-start behavior and quicker engine turnover, which is particularly useful for track days, fast road starts, and repeated starts at servicing events.
Cold cranking and real-world starting
You can expect improved starting performance thanks to lithium batteries’ lower internal resistance and better voltage stability under high load. If you often ride in cooler weather or do a lot of stop-start urban riding, the Skyrich unit should give you more reliable first starts.
Keep in mind, however, that lithium batteries can be more sensitive to very low temperatures than some lead-acid chemistries. While you’ll still usually start better, if you store your bike outdoors in freezing conditions, you should consider a battery heater or store the bike in a warmer area to maximize battery life and immediate starting capacity.
Charge acceptance and recharge speed
Lithium-ion packs typically accept charge more readily and recharge faster than lead-acid equivalents if the charging system is appropriately matched. This means after extended rides or short pit stops, the battery can regain usable charge quicker, which benefits endurance riders and riders doing repeated short trips.
You’ll want to avoid prolonged undercharging or overcharging. Many riders use an external lithium-compatible charger for maintenance charging during storage or periods of infrequent use. If your bike’s on-board charging system isn’t optimized for lithium chemistry, consider a small external charger to keep the pack healthy.
Installation guide — step by step
Installing a motorcycle battery is straightforward, but you should take your time and be safe. You’re replacing the battery that powers everything from the starter to the ECU, so correct installation matters.
Before you start, disconnect the negative terminal on the old battery first to prevent short circuits, then the positive. Remove any hold-downs or straps, and lift out the old battery. Position the Skyrich battery in the tray, ensuring the terminal orientation matches your wiring harness. Refasten hold-downs, attach positive cable first, then negative, and ensure connections are tight and free of corrosion.
Tools and supplies you’ll need
You’ll need a few basic hand tools and a safe workspace to do the swap. Gather a socket set or spanners that match your battery terminal nuts, a screwdriver if required for covers or clamp hardware, and possibly an adapter lead if terminals don’t exactly match your bike harness.
A torque wrench is nice to ensure you don’t over-tighten battery terminals; snug and secure is ideal. Have dielectric grease or a corrosion-preventing compound on hand to lightly coat terminal surfaces for future protection, and keep the included work gloves handy to avoid cuts or grease on your hands.
Detailed steps with safety tips
- Park the bike on a flat, stable surface and switch off the ignition. Leave the key out while you work to prevent accidental powering of the bike.
- Disconnect the negative (-) cable from the old battery first, then the positive (+) cable. You’ll reduce the chance of shorting the system by following this order.
- Remove the old battery hold-downs and carefully lift the battery out. Keep it upright; if it’s a sealed lithium pack it won’t leak, but it’s good practice.
- Compare the new battery’s terminal locations with the old one. Confirm polarity and that cable lengths can reach the posts comfortably.
- Place the Skyrich battery in the tray with protective padding if necessary. Secure it with the original hold-downs or the hardware supplied.
- Attach the positive (+) cable first to the new battery, then the negative (-) cable. Ensure terminals are tight and won’t vibrate loose.
- Turn on the ignition and test: check that the dash lights come on and try a normal start. Confirm all electronics work as expected.
- If you see error codes or odd behavior, recheck connections and battery voltage; if issues persist, consult a mechanic or an Aprilia dealer.
Always wear gloves and eye protection when working with any battery to protect against potential sparks or acid (mostly a concern with older lead-acid batteries, but a good habit).
Charging, maintenance, and storage best practices
You want to keep this battery performing well for many seasons, and practice matters. Lithium packs are low-maintenance compared with lead-acid, but they’re not maintenance-free.
For regular riding, the bike’s charging system will normally keep the battery topped up. If you store the bike for longer than a few weeks, use a dedicated lithium-compatible trickle charger or maintainer. This will keep the battery at a healthy storage voltage without overcharging. If you store the bike in very hot conditions, try to place it in a cooler area; extreme heat shortens lithium battery lifespan.
Initial charging and “first use” recommendations
When you receive the Skyrich HJTX14H-FP, check the manufacturer’s instructions about initial charging. Often, these batteries ship at partial charge and are ready to install straight away, but a full initial charge with a lithium-compatible charger is a good practice. You’ll ensure all cells are balanced, maximizing early life performance.
After installing, run a full charge cycle and then do a couple of short rides to let the onboard charging system balance the pack while riding. If your bike will sit unused for a month or more, hook up the maintainer to keep it in the ideal storage voltage window.
Long-term storage and winterizing tips
Store the battery at around 30–50% state of charge for long-term storage if you can remove it, or use a smart lithium maintainer to hold it at the recommended storage voltage. Avoid storing at 100% charge for extended periods and also avoid leaving it fully discharged. Extreme temperatures—both cold and heat—affect longevity, so plan storage locations accordingly.
If you remove the battery from the bike, disconnect it carefully and keep it in a cool, dry place off the concrete floor. Check charge every 1–2 months with a small lithium charger or voltmeter and top up as needed.
Safety and handling
You’ll handle the battery more safely if you follow a few important precautions. Lithium batteries can present fire risks if physically damaged or charged improperly, so treat them with respect.
Never short-circuit the terminals and avoid crushing, puncturing, or subjecting the pack to severe impacts. Use only lithium-compatible chargers and avoid jump-starting from high-powered sources that can create voltage spikes. If the battery is swollen, hot, or emits an unusual smell, remove it from service and recycle it through a proper facility—do not continue to use it.

Before you buy, make sure you understand the warranty terms—length of coverage, what is and isn’t covered, and whether the warranty is handled by the manufacturer or the retailer. Skyrich and many sellers offer limited warranties on defects and failure, but conditions often require correct installation and charging practices.
Check the return policy of the seller in case the unit doesn’t physically fit your bike or arrives with damage. Keep all packaging, receipt, and serial numbers in case you need to make a claim. If you’re buying from an online marketplace, read seller feedback and confirm how warranty claims are processed.
Practical scenarios where this battery really shines
You’ll see the most benefit if you’re a weekend track rider, a sport-touring enthusiast who wants every bit of weight savings, or an owner who values the quick, reliable starts that lithium batteries offer. If you do frequent short rides but still want dependable starting after long idle periods, the low self-discharge will be appreciated.
If you ride in very cold climates regularly or you have an older charging system with voltage spikes, you’ll need to be more careful; the benefits still exist, but you’ll pair the battery with a charging strategy to protect it.
Troubleshooting common issues
If your bike displays error codes, starts intermittently, or the battery appears dead shortly after installation, take these steps. Verify terminal connections are tight and correctly polarized, check battery voltage with a multimeter, and confirm the charging system is producing the expected voltage range while the engine is running.
If the battery reads low after a proper charge and a normal ride, investigate parasitic drains (alarm systems, accessories, or aftermarket electronics). If the battery shows physical swelling, extreme heat after charging, or a burning odor, stop using it immediately and take it to a professional—these are signs of cell failure or damage.
Environmental and disposal considerations
You’ll want to dispose of the old battery responsibly. Lithium-ion packs require special recycling; they should not go in household trash. Most motorcycle shops, recycling centers, or battery retailers will accept old batteries for proper recycling.
When storing a lithium battery at end of life, don’t crush or incinerate it; take it to a certified recycling or hazardous waste facility. Responsible disposal helps prevent environmental harm and reduces the risk of fires associated with damaged lithium packs.
