The Motobatt YTX4LBS-YB4LB-YT4LBS-YTZ5S from the Quadflex range is a motorcycle battery with 4 Ah and 70 A of cold cranking current (EN), designed for motorcycles, scooters, quads and personal watercraft. Its 114 × 70 × 87 mm make it the exact replacement for the 4 Ah battery fitted as standard to many motorcycles.

- AGM: faster recharging and better cycle resistance than a conventional battery.
What the Motobatt YTX4LBS-YB4LB-YT4LBS-YTZ5S is for
With 4 Ah, the Motobatt YTX4LBS-YB4LB-YT4LBS-YTZ5S covers the starting of motorcycles, scooters, quads and personal watercraft. The JIS code on your current battery label is the safest way to confirm equivalence. Check that it matches your current battery in dimensions, terminals and hold-down: this reference has a weight of 1.57 kg.
Size, terminals and hold-down of the Motobatt YTX4LBS-YB4LB-YT4LBS-YTZ5S
The Motobatt YTX4LBS-YB4LB-YT4LBS-YTZ5S is made in the 114 × 70 × 87 mm format and weighs 1.57 kg. Before replacing it, measure your current battery tray: if all three dimensions and the terminal positions match, the swap is direct and needs no adapters.
The Motobatt YTX4LBS-YB4LB-YT4LBS-YTZ5S: Quadflex range and AGM technology
The YTX4LBS-YB4LB-YT4LBS-YTZ5S is part of the Motobatt Quadflex range. Choosing the right reference within the series comes down to capacity, dimensions and terminals: technology and quality are common to the whole family.
AGM means the acid is held in a glass mat instead of floating free. That is why the battery can be installed in the cabin without gases, survives more cycles and recovers its charge quickly.
What Motobatt does differently
Motobatt batteries stand out for capacity and cranking current above the original battery in the same tray, thanks to a compact AGM design and the four-terminal Quadflex system. At baterias.com we work directly with the manufacturer or its official distributor: real stock, brand-new product and official warranty.
Manufacturer's warranty
The Motobatt YTX4LBS-YB4LB-YT4LBS-YTZ5S comes with the manufacturer's official warranty. The warranty does not cover discharge through prolonged inactivity: if the bike stands for months, use a trickle charger.
How to make it last longer
Avoid repeated cranking attempts on a cold bike for long: if it does not start on the third try, let the battery rest for a minute. Check the resting voltage before the season (above 12.6 V on a charged battery) and make sure the terminals are clean and tight.
Shipping, delivery and returns
Same-day dispatch from our warehouse for in-stock orders placed before 6:00 pm: 24-48 working hours in mainland Spain and Portugal, 3 to 5 days in the islands and the rest of Europe. Returns are accepted for 14 days if the battery has not been used (free collection on the Iberian mainland). You will receive tracking by email.

Frequently asked questions
How is the Motobatt YTX4LBS-YB4LB-YT4LBS-YTZ5S battery installed in the vehicle?
In most motorcycles it fits in 15-30 minutes with a 10 mm wrench; if the battery is under the seat or in the boot the time can double. See the step-by-step guide on our blog. Quick summary: 1) switch off the engine and remove the key; 2) locate the original battery (engine bay, boot or under seat); 3) disconnect the negative (−) terminal first, then the positive (+); 4) loosen the hold-down clamp and remove the old battery; 5) fit the new one in the same orientation — match the polarity shown on the product sheet; 6) connect the positive (+) first, then the negative (−). On motorcycles with Start-Stop or BMS, register the battery via OBD so the alternator applies the correct charging profile.
What is the service life of the YTX4LBS-YB4LB-YT4LBS-YTZ5S model?
Expected lifespan of the Motobatt YTX4LBS-YB4LB-YT4LBS-YTZ5S is 4 to 7 years in regular use (depends on technology and climate). In cold regions it drops slightly due to cold-start stress; in very hot regions it also drops because of electrolyte evaporation. To extend its life: avoid deep discharges (headlights on with engine off), have the alternator checked yearly, and keep the battery clean and properly secured.
What are the measurements of the YTX4LBS-YB4LB-YT4LBS-YTZ5S model?
Dimensions (length × width × height) are 114×70×87 mm — also written as 114x70x87 mm — following the European DIN standard. Always measure the space in your motorcycle before buying: even one extra millimetre can prevent the hold-down clamp from closing. The height shown includes the terminals.
Is the YTX4LBS-YB4LB-YT4LBS-YTZ5S valid for my vehicle?
Three options to confirm: 1) enter your number plate in the finder (DGT/DVLA/KBA auto-detect your model and engine); 2) check the "Compatible vehicles" tab on this page, where we list every vehicle verified by our technical team; 3) if you cannot find your model, message us on WhatsApp with brand, model, engine and year — we reply during business hours (Mon–Fri 10:00–13:30 and 16:40–18:00 (Spanish time, CET)). The YTX4LBS-YB4LB-YT4LBS-YTZ5S typically fits a wide range of European vehicles thanks to its standard DIN case format.
What are the equivalents of the YTX4LBS-YB4LB-YT4LBS-YTZ5S model?
Directly interchangeable batteries (same dimensions, same polarity, same Ah and CCA) are the OEM equivalents from leading brands: Bosch, Tudor, Exide and, depending on the model, Banner or Yuasa. Exact equivalence depends on technology — an EFB cannot be replaced with a conventional battery in Start-Stop motorcycles. See the "Equivalents" section to view recommended options at the same performance level.
