Ritar EV12-100S 12V 100Ah 620A is a deep cycle battery for floor scrubbers and sweepers: drained through the shift and recharged overnight, with no water or gassing in a public space. 306.5×168.5×215 mm case, 31 kg.

Ritar’s EV series is designed for the frequent deep discharge of electric vehicles: a patented deep-cycle active material formula, strong Pb-Ca-Sn cadmium-free grids, thick plates and a high-performance AGM separator. Over 300 cycles at 100 % depth of discharge. Sealed (VRLA) and maintenance-free, with self-discharge below 3 % per month. The whole series at Ritar EV batteries.
306.5×168.5×215 mm case, 31 kg. 12 V and 100 Ah, 620 A cold cranking (CCA) and a maximum discharge current of 1000 A for 5 seconds.

In most devices 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 devices with Start-Stop or BMS, register the battery via OBD so the alternator applies the correct charging profile.
Expected lifespan of the Ritar EV12-100S 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.
Dimensions (length × width × height) are 307×169×215 mm — also written as 307x169x215 mm — following the European DIN standard. Always measure the space in your device before buying: even one extra millimetre can prevent the hold-down clamp from closing. The height shown includes the terminals.
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 devices. See the "Equivalents" section to view recommended options at the same performance level.
