# 55Ah batteries We stock 22 batteries of 55 Ah (AGM, lead-acid, EFB) priced between 55.14 € and 361.16 €, VAT included. Amp-hour capacity is the total energy the battery stores: when replacing, always fit equal or slightly higher capacity than the original, never lower. 55Ah is the typical capacity for petrol superminis and small hatchbacks (Citroën C3, Fiat Panda, Renault Clio and similar). A quality conventional battery is plenty for this segment if the car has no Start-Stop. At this rating we stock AGM, lead-acid, EFB. Start-Stop golden rule: never downgrade technology — factory AGM must be replaced with AGM; factory EFB can be upgraded to AGM but never downgraded to conventional. Brands available right now in at 55 Ah: Fullriver (5), Optima (4), Long (4), Exide (3), Tudor (2), Ritar (1). All with official warranty and live stock. Cold cranking amps (CCA, EN standard) of the listed models range from 350 to 765 A. When replacing, pick a CCA equal or higher than your original: every amp counts in winter. ## Available models | Modelo | V | Ah | CCA (EN) | L×An×Al mm | Tech | Polarity | € VAT incl. | Stock | URL | |---|---|---|---|---|---|---|---|---|---| | Marine battery Optima BTDC-4.2 12V 55Ah AGM | 12 | 55 | 765 | 254×175×200 | AGM ESPIRAL | | 216,23 | ✓ | https://baterias.com/gb/battery-optima-blue-top-btdc-42-8016-253-12v-55ah | | Caravan battery Optima YTU-4.2 12V 55Ah AGM | 12 | 55 | 765 | 254×175×200 | AGM ESPIRAL | | 210,15 | ✓ | https://baterias.com/gb/battery-optima-yellow-top-ytu-42-8014-254-12v-55ah | | Caravan battery Optima YTS-2.1 6V 55Ah AGM | 6 | 55 | 765 | 255×90×206 | AGM ESPIRAL | + left | 160,75 | ✓ | https://baterias.com/gb/battery-optima-yellow-top-yts-21-8018-356-12v-55ah | | Start-Stop battery Tudor TL550 12V 55Ah 540A EFB | 12 | 55 | 540 | 207×175×190 | EFB | | 76,39 | ✓ | https://baterias.com/gb/battery-tudor-tl550-55ah-480a | | Start-Stop battery Exide EL550 12V 55Ah 540A EFB | 12 | 55 | 540 | 207×175×190 | EFB | | 95,42 | ✓ | https://baterias.com/gb/battery-exide-el550-12v-55ah-480a | | Caravan battery Optima YTS-4.2 12V 55Ah AGM | 12 | 55 | 765 | 254×175×200 | AGM ESPIRAL | | 213,10 | — | https://baterias.com/gb/battery-optima-yellow-top-yts-42-8012-254-12v-55ah | | Car battery Tudor TC550 12V 55Ah 460A | 12 | 55 | 460 | 242×175×190 | Flooded | | 55,14 | — | https://baterias.com/gb/battery-tudor-tc550-12v-55ah-460a | | Deep-cycle battery MK Powered M55-12 SLD M 12V 55Ah AGM | 12 | 55 | 0 | 226×135×214 | AGM | | 198,48 | — | https://baterias.com/gb/battery-mk-m55-12-sld-m-12v-55ah | | Marine battery Fullriver DC55-12 12V 55Ah AGM | 12 | 55 | 400 | 229×138×212 | AGM | | 207,24 | — | https://baterias.com/gb/battery-agm-fullriver-dc55-12-12v-55ah | | Ritar FT12-55 stationary UPS battery 12V 55Ah AGM | 12 | 55 | 0 | 291×106×230 | AGM | | 223,25 | — | https://baterias.com/gb/battery-ritar-ft12-55-12v-ft-agm | | Car battery Exide EB558 12V 55Ah 620A | 12 | 55 | 620 | 230×180×186 | PLOMO/ACIDO | | 156,08 | — | https://baterias.com/gb/battery-exide-eb558-12v-55ah-620a | | Car battery Exide EC550 12V 55Ah 460A | 12 | 55 | 460 | 242×175×190 | PLOMO/ACIDO | | 68,10 | — | https://baterias.com/gb/battery-exide-ec550-12v-55ah-460a | | Car battery Tudor TB558 12V 55Ah 620A | 12 | 55 | 620 | 230×180×186 | PLOMO/ACIDO | | 163,87 | — | https://baterias.com/gb/battery-tudor-tb558-60ah-640a | | Deep-cycle battery Long WP55-12N 12V 55Ah AGM | 12 | 55 | 0 | 226×135×214 | AGM | | 218,80 | — | https://baterias.com/gb/battery-long-wp55-12n-12v-55ah | | Deep-cycle battery Kronobat ES55-12 12V 55Ah AGM | 12 | 55 | 0 | 226×135×214 | AGM | | 194,36 | — | https://baterias.com/gb/best-price-battery-12v-55ah-agm-es55-12 | | Marine battery Fullriver DCG55-12 12V 55Ah AGM | 12 | 55 | 0 | 271×170×189 | AGM | | 242,12 | — | https://baterias.com/gb/battery-fullriver-dcg55-12-12v-55ah | | Deep-cycle battery Fullriver HC55 12V 55Ah AGM | 12 | 55 | 620 | 229×138×212 | AGM | | 361,16 | — | https://baterias.com/gb/battery-fullriver-hc55-12v-55ah-620-cca | | Deep-cycle battery Long LG55-12N 12V 55Ah GEL | 12 | 55 | 0 | 226×135×214 | GEL | | 211,75 | — | https://baterias.com/gb/battery-long-lg55-12n-12v-55ah | | Deep-cycle battery Long WP55-12 12V 55Ah AGM | 12 | 55 | 0 | 226×135×229 | AGM | | 218,80 | — | https://baterias.com/gb/battery-long-wp55-12-12v-55ah | | Deep-cycle battery Long WP55-12NE 12V 55Ah AGM | 12 | 55 | 0 | 226×135×214 | AGM | | 218,80 | — | https://baterias.com/gb/battery-long-wp55-12ne-12v-55ah | | Stationary battery Q-battery 12LS-55 12V 55Ah AGM | 12 | 55 | 0 | 229×138×210 | AGM | | 230,06 | — | https://baterias.com/gb/battery-q-battery-12ls-55-12v-55ah | | Marine battery Fullriver FT620-51 12V 55Ah AGM | 12 | 55 | 620 | 229×138×230 | AGM | | 264,05 | — | https://baterias.com/gb/battery-fullriver-ft620-51-12v-55ah-620a | | Marine battery Fullriver FFD55-12 12V 55Ah AGM | 12 | 55 | 350 | 229×138×212 | AGM | | 337,25 | — | https://baterias.com/gb/battery-fullriver-ffd55-12-12v-55ah-350a | | Traction battery Sonnenschein GF12050V 12V 55Ah GEL | 0 | 55 | 0 | 275×175×190 | GEL | | 282,06 | — | https://baterias.com/gb/battery-sonnenschein-gf12050v-12v-55ah | | Traction battery Sonnenschein GF12050VG 12V 55Ah GEL | 0 | 55 | 0 | 278×175×190 | GEL | | 286,65 | — | https://baterias.com/gb/battery-sonnenschein-gf12050vg-12v-55ah | ## Frequently asked questions ### How much does a 55Ah battery cost? Between 55.14 € and 361.16 €, VAT included, depending on technology (AGM, lead-acid, GEL) and brand. Price grows with cold cranking amps (CCA) and Start-Stop technologies such as EFB or AGM. ### Can I fit a battery with more capacity than 55Ah? Yes, as long as the dimensions and terminal layout match your tray and the CCA is equal or higher than the original. What you should never do is fit LESS capacity than the manufacturer specifies. ### What sizes do 55Ah batteries usually have? The most common sizes for this rating are 226x135x214 · 229x138x212 · 254x175x200 (length × width × height, in mm). Always check your tray before buying: each product page lists exact dimensions. ### AGM, EFB or conventional for my car? It depends on the equipment: with advanced Start-Stop (regenerative braking) fit AGM; with basic Start-Stop, EFB — or AGM, never less —; without Start-Stop a quality conventional battery is enough. On this page you can filter by technology to see only the ones that suit your case. ### How do I know which polarity I need? Look at your current battery from the front with the terminals on the far side: if the positive (+) sits on the right it is right polarity; on the left, left polarity. Every card shows the polarity and you can filter by it above — with the wrong polarity the cables will not reach the terminal. --- Updated: 2026-08-03 · https://baterias.com/gb/batteries-55ah
