It replaces the original battery without adaptation in motorcycles with a 205 × 90 × 165 mm format: same 21 Ah capacity and the positive terminal on the right. - Resistant to the vibration typical of two wheels. - Energetic cranking for high-compression engines. - AGM technology: absorbed electrolyte, no spills, can be mounted at an angle. - Same JIS code as the original battery: fits first time. ### What the Exide AGM12-23 is for With 21 Ah, the Exide AGM12-23 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 7 kg, M04 terminals and B0 hold-down. ### The Exide AGM12-23: Moto AGM range and AGM technology The AGM12-23 is part of the Exide **Moto AGM** 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 (Absorbent Glass Mat) technology seals the electrolyte in glass microfibre. The result is a maintenance-free battery that is highly vibration-resistant and able to withstand deep discharges that would ruin a classic lead-acid battery. ### Size, terminals and hold-down of the Exide AGM12-23 In terms of format, the Exide AGM12-23 measures 205 × 90 × 165 mm (length × width × height) and weighs 7 kg. The positive terminal on the right decides which side the cables end up on: it is the detail that causes most buying mistakes, so check it before ordering. It uses a B0 hold-down and M04 terminals, the system that anchors and connects it in the vehicle. 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. ### Why choose Exide batteries Exide is one of the world's largest battery manufacturers and an original-equipment supplier to many car makers. Its European plants produce starter, industrial and leisure batteries under original-equipment quality controls. All the Exide batteries in our catalogue are genuine product, recently manufactured and covered by the manufacturer's warranty. ### Usage and maintenance tips Charge with a charger that has an AGM mode: it limits the voltage and protects the glass-fibre separators. If the bike spends the winter standing, connect a trickle charger: deep discharge through inactivity is the first cause of premature failure. ### Warranty and coverage The Exide AGM12-23 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. ### Delivery times and returns Orders placed **before 6:00 pm** with the battery in stock ship the same day. Delivery in mainland Spain and Portugal takes 24-48 working hours; for the Balearic Islands and the rest of the European Union allow 3 to 5 working days. You have **14 days** to return an unused battery; in mainland Spain and Portugal collection is free. We email you the tracking number as soon as the parcel ships. ## Frequently asked questions ### Is the Exide YTX24HL-BS an AGM battery and what are the benefits of AGM? Yes. The Exide YTX24HL-BS is AGM (Absorbent Glass Mat): sealed lead-acid, with the electrolyte absorbed in glass fibre. Its advantages: more charge/discharge cycles than a conventional battery and better heat tolerance. ### How should this motorcycle battery be charged? With a 12 V motorcycle charger delivering at most 10 % of its capacity: 2.1 A for its 21 Ah. High-current car chargers can damage it. If the bike is laid up for the winter, keep it on a maintenance charger. ### Does it need maintenance? No: being AGM, it is sealed and nothing needs topping up. Just keep it charged if the bike stands for a long time. ### What is the service life of the YTX24HL-BS model? There is no exact figure: for a battery such as the Exide YTX24HL-BS (AGM), a reasonable guide is 4 to 6 years, keeping it charged when the bike is not in use. Actual lifespan varies with climate (cold starts, heat evaporating the electrolyte), with usage and short journeys, with the condition of the alternator and charging system, with power draw while parked and with maintenance. ### What are the dimensions of the Exide YTX24HL-BS battery? It measures 205×90×165 mm in length × width × height, with the terminals included in the height. Measure the battery tray before ordering: a one-millimetre difference is enough for the hold-down clamp not to close. ### Which side is the positive terminal on this battery? It has the positive on the right (polarity). If your current battery has its positive on the other side, this one is not suitable without longer cables or a reconfigured system (short-circuit risk). Put it in front of you, terminals towards you: the post with the red ring and the + sign is the positive. ### Is the YTX24HL-BS valid for my vehicle? The quickest way is to enter your number plate in the finder: DGT/DVLA/KBA detect model and engine. You can also look at the "Compatible vehicles" tab, verified by our technical team, or send us make, model, engine and year on WhatsApp; we answer during business hours (Mon–Fri 10:00–13:30 and 16:30–18:00 (Spanish time, CET)). In every case, the motorcycle manufacturer's specifications (owner's handbook) take precedence. ### Which batteries are equivalent to the Exide YTX24HL-BS? See the "Equivalents" section of this page for the recommended options at the same performance level. A battery interchangeable with the Exide YTX24HL-BS must match it on dimensions (205×90×165 mm), polarity (positive on the right), capacity (21 Ah) and cranking current (350 A). ### Exide AGM12-23 or Exide ETX24HL-BS: which one to choose? Sister reference of the AGM12-23, practically identical on paper. Compared with the AGM12-23 it has the same Ah and cranking power. It costs 8,50 € less. Choose by price and availability: in real use you will not notice a difference. ## Equivalent batteries - [EXIDE ETX24HL-BS](https://baterias.com/gb/battery-exide-etx24hl-bs-12v-21ah-350a) ## Technical team (editorial authorship) The FAQs, guides and comparisons on this site are reviewed by the baterias.com technical team — automotive battery specialists since 2012. → https://baterias.com/gb/technical-team --- *baterias.com — Automotive batteries · 2026-11-10*
