They weigh far less than an equivalent lead-acid battery, deliver more cranking current, barely self-discharge and include a BMS that protects against overcharge and deep discharge. Pick yours by the code of your current battery: every Exide ELT model directly replaces the lead-acid YTX, YTZ and YT references (*ELTX9 = YTX9-BS, ELTZ7S = YTZ7S, ELTX14H = YTX14-BS…*), same size and polarity. Express delivery and official warranty. Buy online with **express delivery in 24-48 h**, official Exide warranty and technical advice. Not sure which model your bike takes? Find it by make and model in the [motorcycle battery finder](https://baterias.com/gb/motorcycle-batteries). ## Lithium, AGM or lead-acid: what really changes A LiFePO4 lithium motorcycle battery is not just "lighter": it changes service life, self-discharge and starting behaviour. Indicative comparison: LiFePO4 lithium (Exide Li-Ion) AGM Conventional lead-acid **Weight** A third to a half Reference Similar to AGM **Life cycles** Over 2,000 300–500 200–300 **Monthly self-discharge** 2–3% 3–5% 5–10% **Cold cranking** Very high (wake up for a few seconds below 0 °C) Good Average **Maintenance** None, built-in BMS None Check acid level **Mounting position** Any Any Upright only **Price** Higher Medium Low ## Exide, a world-leading manufacturer **Exide Technologies** is one of the world's leading battery manufacturers, with over a century of history and factories across Europe, and owns the **Tudor** brand, the historic reference in Spain. Its Li-Ion motorcycle range applies that experience to LiFePO4 cells: built-in BMS, the same dimensions as the lead-acid batteries they replace and an official manufacturer warranty. ## Exide Li-Ion technical data and equivalents Find the code of your current battery (YTX, YTZ or YT) on its label and pick the Exide model that replaces it.

Before switching, check your motorcycle manufacturer's recommendations. As a rule, any 12 V petrol motorcycle with a charging regulator in good condition (13.8–14.6 V) will usually accept a lithium battery.

If it has been in storage, charge it before fitting. - Use a charger with a lithium mode (or a lead-acid charger without desulphation or equalisation). Never exceed 14.6 V. - Below freezing, switch the ignition on for a few seconds before starting so the BMS wakes the battery. Compatible chargers: [battery chargers](https://baterias.com/gb/battery-chargers) and [Motobatt chargers](https://baterias.com/gb/motobatt-battery-chargers).

As a general rule, any 12 V petrol motorcycle with a charging regulator in good condition (13.8–14.6 V) will usually accept a lithium battery. If yours meets that condition, choose the Exide ELT model matching the code of your current battery: size and polarity match. ### **How long does a lithium motorcycle battery last?** In normal use, several times longer than lead-acid: over 2,000 charge cycles versus 300–500 for an AGM. The BMS prevents the deep discharges that shorten life. ### **Does it cope with the cold?** Yes. Below 0 °C the battery needs to "wake up": switch the ignition on for a few seconds (lights, dash) before starting and it recovers full power. ### **Will my usual charger work?** A lead-acid charger without desulphation or equalisation modes works; a charger with a lithium mode is ideal. Never exceed 14.6 V. ### **How much lighter is it than lead-acid?** A third to a half: the ELTX9 weighs 0.7 kg versus roughly 3 kg for a lead-acid YTX9-BS. ### **Does it need maintenance or activation?** No. It arrives sealed and charged, with no acid, and the built-in BMS protects against overcharge and deep discharge. Just recharge it if it sits unused for months. ### **What about warranty and delivery?** Official Exide warranty and express delivery in 24-48 h; free returns within 14 days. ## You may also like - [AGM and conventional motorcycle batteries](https://baterias.com/gb/motorcycle-batteries) - [Motobatt batteries](https://baterias.com/gb/batteries-motobatt) - [Varta Powersports](https://baterias.com/gb/batteries-varta) - [Battery chargers](https://baterias.com/gb/battery-chargers) ## Products in this category | Product | Brand | Price | |---|---|---| | [Motorcycle battery Exide ELTX20H 12V 7Ah 380A Li-Ion](https://baterias.com/gb/battery-exide-eltx20h-12v-84wh-380a) | EXIDE | 190,40 € | | [Motorcycle battery Exide ELTZ7S 12V 2Ah 150A Li-Ion](https://baterias.com/gb/battery-exide-eltz7s-12v-29wh-150a) | EXIDE | 72,20 € | | [Motorcycle battery Exide ELTX9 12V 3Ah 180A Li-Ion](https://baterias.com/gb/battery-exide-eltx9-12v-36wh-180a) | EXIDE | 84,30 € | | [Motorcycle battery Exide ELT12B 12V 5Ah 260A Li-Ion](https://baterias.com/gb/battery-exide-elt12b-12v-60wh-260a) | EXIDE | 163,95 € | | [Motorcycle battery Exide ELTZ14S 12V 5Ah 290A Li-Ion](https://baterias.com/gb/battery-exide-eltz14s-12v-60wh-290a) | EXIDE | 149,40 € | | [Motorcycle battery Exide ELTZ5S 12V 2Ah 120A Li-Ion](https://baterias.com/gb/battery-exide-eltz5s-12v-24wh-120a) | EXIDE | 66,60 € | | [Motorcycle battery Exide ELTX12 12V 4Ah 210A Li-Ion](https://baterias.com/gb/battery-exide-eltx12-12v-42wh-210a) | EXIDE | 106,20 € | | [Motorcycle battery Exide ELTX14H 12V 4Ah 240A Li-Ion](https://baterias.com/gb/battery-exide-eltx14h-12v-48wh-240a) | EXIDE | 110,80 € | | [Motorcycle battery Exide ELT9B 12V 3Ah 190A Li-Ion](https://baterias.com/gb/battery-exide-elt9b-12v-36wh-190a) | EXIDE | 90,80 € | | [Motorcycle battery Exide ELTZ10S 12V 4Ah 230A Li-Ion](https://baterias.com/gb/battery-exide-eltz10s-12v-48wh-230a) | EXIDE | 127,40 € | | [Motorcycle battery Fulbat FLTK01 2Ah 140A LiFePO4](https://baterias.com/gb/battery-fulbat-fltk01-2ah-140a) | FULBAT | 115,10 € | | [Motorcycle battery Fulbat FLT7B/9B 4Ah 240A LiFePO4](https://baterias.com/gb/battery-fulbat-flt7b-9b-4ah-240a) | FULBAT | 139,04 € | | [Motorcycle battery Fulbat FLTX7A/9/12/14 FLTZ10S/12S/14S 5Ah 300A LiFePO4](https://baterias.com/gb/battery-fulbat-fltx7a-9-12-14-fltz10s-12s-14s-5ah-300a) | FULBAT | 149,30 € | | [Motorcycle battery Fulbat FLT12B/14B 6Ah 360A LiFePO4](https://baterias.com/gb/battery-fulbat-flt12b-14b-6ah-360a) | FULBAT | 174,95 € | | [Motorcycle battery Fulbat FLTX20HL 12Ah 720A LiFePO4](https://baterias.com/gb/battery-fulbat-fltx20hl-12ah-720a) | FULBAT | 298,34 € | ## Technical team (editorial authorship) The FAQs, guides and comparisons on this site are reviewed by the baterias.com technical team — over 25 years of experience validating automotive batteries. → https://baterias.com/gb/technical-team --- *baterias.com — Automotive batteries · 2026-10-06*
