You’re considering the COMPATIBLE WITH BMW F 850 GS 850 2018-2020 LITHIUM BATTERY SPECIFIC LITHIUM ION SKYRICH BATTERY FOR MOTORCYCLE SCOOTER 150X87X93 LIGHT RECHARGEABLE, and this section helps you understand what that long title actually means. This battery is sold as a Skyrich HJTX14H-FP lithium-ion unit designed to be a drop-in replacement for specific motorcycle and scooter models; it promises reduced weight and reliable rechargeability compared with older lead-acid types.
You’ll find the seller highlights that the title indicates the specific model fitment, so confirm the HJTX14H-FP matches your OEM battery reference before buying. The listing also mentions dimensions and a couple of extras — those practical details help you check clearance in the battery compartment and what you’ll get in the box.
What the product name tells you
You’ll recognize the model targeted at BMW F 850 GS (2018–2020) in the title, which signals compatibility rather than a BMW-manufactured part. The long name bundles chemistry type (lithium ion), brand (Skyrich), and the physical size (150 x 87 x 93 mm), so you know at a glance where it’s meant to fit.
You should still cross-check your bike’s existing battery label for model numbers and terminal placement, since fitment varies by year and aftermarket parts may use different terminal orientations.
Key Specifications
Below you’ll find the main specs pulled from the listing and written in clear terms so you can verify fit and electrical match before purchasing. These are the core facts you’ll use to compare against your bike’s requirements.

You’ll notice the specs focus on physical size, model code, and terminal placement — the three things that most often determine whether a battery will physically and electrically fit your bike. If something doesn’t match, the battery may not seat correctly or the terminals may not align.
Notes about the specs you should check
You’ll want to confirm the HJTX14H-FP model matches your bike’s OEM battery part number and that the positive terminal position (POS. SX — positive on the left) matches your bike’s wiring harness orientation. Also double-check that your motorcycle’s charging system is compatible with lithium-ion chemistry to avoid under- or overcharging issues.
If any of those items don’t line up, you risk installation headaches or reduced battery lifespan.
Compatibility
You should treat compatibility as the first checkpoint before purchase. The title names BMW F 850 GS (2018–2020) as compatible, but compatibility claims from sellers are best confirmed against your bike’s battery label or owner’s manual.
You’ll want to confirm three things: the OEM reference number, the battery’s physical dimensions, and the terminal placement. Even if the dimensions look close, small differences in bracket mounts or connector types can make installation more difficult than expected.
How to confirm fitment the right way
You’ll check your current battery’s printed model number and compare the HJTX14H-FP model code. Measure the battery compartment and compare the 150 x 87 x 93 mm dimensions, and verify terminal orientation so you don’t create reversed-polartiy connections.
If you can’t find the OEM number, take a photo of your current battery and the terminal setup and compare it with the Skyrich listing. If in doubt, reach out to the seller with those photos to get confirmation.
Performance and Power
You’ll expect a lithium-ion battery like the Skyrich HJTX14H-FP to deliver better power-to-weight ratio than traditional lead-acid batteries, giving cranking power with significantly reduced mass. That can improve handling slightly and make the bike easier to start after long idle periods.
Because the listing emphasizes “light rechargeable,” you should take that to mean the battery is optimized for low weight and frequent recharge cycles rather than absolute reserve capacity. For everyday street riding and typical touring, this trade-off is usually favorable; for extended storage or heavy accessory loads, you’ll want to monitor voltage and charging closely.
Real-world riding performance
You’ll find starting will generally be crisp for normal conditions — the battery is sized for routine engine starts on the listed motorcycles. If you run a lot of high-draw accessories (heated gear, extra lighting, winches, etc.), you’ll need to make sure the bike’s charging system keeps the battery topped up.
For reliability over multiple seasons, you should pay attention to charge control and avoid leaving the bike parked with electronics connected, since lithium batteries can be more sensitive to long-term parasitic draws.
Starting Power and Cold Cranking
You’ll want a battery that reliably delivers high current at startup, especially in cooler climates where starting draws increase. The HJTX14H-FP is designed to provide sufficient cranking amps for compatible motorcycles, but the listing does not publish explicit cold cranking amp (CCA) numbers.
Because explicit CCA data isn’t listed, you should compare real-world feedback from other riders on the same model or contact the seller/manufacturer for CCA figures. That will give you better assurance whether the battery will start your bike consistently in your climate.
Tips for cold-weather use
You’ll minimize starting issues by ensuring the battery is fully charged before exposure to cold and by storing the bike in a warmer place if possible. If you live where temperatures often drop below freezing, consider a battery warmer or keeping a compatible charger on hand for top-ups.
If you frequently do short rides where the alternator doesn’t fully recharge the battery, plan on using a smart charger that supports lithium chemistries to maintain battery health.
Weight and Handling
You’ll immediately notice the weight reduction compared with traditional lead-acid batteries, which makes the bike slightly lighter and easier to balance, especially when performing maintenance or lifting the bike onto center stands. The listing highlights the battery as “light rechargeable,” indicating light construction typical of lithium-ion cells.
The reduced mass contributes to a small improvement in handling responsiveness, particularly when performing low-speed maneuvers or carrying the bike on a trailer. However, the change is subtle — it’s a convenience and handling enhancement rather than a dramatic performance upgrade.
How much weight saving to expect
You’ll usually see lithium motorcycle batteries weigh roughly half of a comparable lead-acid unit, but the listing doesn’t provide a specific weight figure. If weight is a high priority for you (racing or performance tuning), ask the seller for the exact weight so you can compare it to your OEM battery.
Installation
You’ll approach installation as a straightforward swap if dimensions and terminal orientation match your bike. Before you start, make sure you have the right tools, a clean workspace, and the correct polarity orientation marked so you don’t reverse the terminals.
Begin by removing the seat and any body panels necessary to access the battery compartment, then disconnect the negative terminal first and the positive second. Remove any brackets or straps holding the old battery, test-fit the Skyrich to confirm it seats properly, and then connect the terminals — positive first, then negative — making sure connections are snug and protected against corrosion.
Step-by-step checklist for a smooth install
You’ll follow these steps to reduce risk and make installation fast:
- Gather tools: basic wrench or socket set, gloves (included), and possibly dielectric grease for terminals.
- Disconnect the negative terminal on the old battery first, then the positive.
- Remove the old battery and clean the tray and connectors.
- Fit the Skyrich HJTX14H-FP into the tray and secure any hold-down brackets.
- Connect the positive terminal first (POS. SX indicates positive on left when viewed from front), then the negative.
- Double-check tightness, apply terminal protection if needed, and replace covers and panels.
Take your time and avoid forcing connectors. If terminal posts or connector types don’t match, you may need small terminal adaptors or an alternate bracket.
Durability and Maintenance
You’ll appreciate that lithium batteries generally tolerate more charge/discharge cycles than lead-acid equivalents and have lower self-discharge rates, which is helpful if you use the bike intermittently. The Skyrich name is commonly associated with motorcycle lithium batteries that emphasize longevity, but actual lifespan depends on how you use and charge the battery.
To get the most out of the battery, maintain consistent charging habits, avoid deep discharges, and store the bike with a proper lithium-compatible maintenance charger if you plan to keep it idle for more than a few weeks.
Routine care recommendations
You’ll preserve battery life by keeping terminals clean and by using a charger and maintainer designed for lithium chemistries. Avoid charging with a charger exclusively meant for lead-acid batteries unless it has a lithium setting; improper charging can reduce lifespan or cause damage.
Charging and Battery Management
You’ll need a charger that’s specifically compatible with lithium-ion motorcycle batteries to properly manage charging curves and cell balancing. The listing states “light rechargeable,” indicating typical onboard charging and external smart chargers should be used rather than trickle chargers made for lead-acid chemistry.
Use a smart lithium charger or maintainer that has a lithium mode, low-voltage detection, and safety cut-offs. These chargers manage charge voltage and current suitable for the cells, and they help prevent overcharging, which is a primary cause of failure in lithium batteries used in motorcycles.
Charging routine you should adopt
You’ll plug in a lithium-capable maintainer after every long ride or anytime the battery falls below a healthy resting voltage. If you store the bike for winter, a periodic top-up with a correct charger will keep the battery in the best condition and avoid deep discharge.
If you notice a drop in performance, measure voltage and specific gravity equivalents using a diagnostic tool and, if needed, top up with a charger rather than relying on the bike’s alternator alone.
Safety Features
You’ll find lithium motorcycle batteries often include protective circuits such as internal cell balancing, overcharge protection, and short-circuit protection, though the listing doesn’t itemize which protections are built into the Skyrich HJTX14H-FP. These protections are crucial for safe operation and for preventing thermal events.
Because product listings vary in the depth of safety information provided, you should request or verify the presence of protective circuitry and compliance with relevant safety standards if you have safety concerns or if you ride in harsh conditions.
Handling precautions
You’ll handle the battery like any lithium-ion device: avoid crushing, puncturing, or exposing it to extreme heat. Don’t attempt to open the battery pack or modify the terminals, and if the battery shows bulging, heavy swelling, or emits unusual odors, stop using it and seek professional disposal.
