Motorcycles can use GEL, AGM, or conventional batteries. GEL batteries are ideal for occasional use. AGM batteries are the best option for heavy use or high-power motorcycles. Always check the polarity before installation.
Polarity indicates which side has the positive (+) terminal. This is critical for motorcycles because some models have the positive terminal on the left and others on the right. Check the label on your current battery or the manufacturer's manual.
Yes. First disconnect the negative (−) wire and then the positive (+) wire. When installing the new one, connect the positive (+) wire first and then the negative (−) wire. Always respect the correct polarity.

Guide to safely replace the battery of the Keeway Flash Flash 50. Estimated time: 10-20 minutes. Tools: 8-10 mm wrenches, 4-6 mm Allen keys or Torx depending on the model. Many bikes require removing the seat or a side panel to reach the battery. Check the manual for fully faired models or those with reverse polarity.

  1. Prepare the motorcycle Put the bike on the centre stand — or, failing that, the side stand — on flat, firm ground. Switch off the ignition, remove the key and wait a few minutes for the engine to cool.
  2. Locate the battery On most motorcycles the battery sits under the seat, behind a side panel or near the fuel tank. On cruisers and adventure bikes it may be under the tank or in a frame compartment. Check the owner's manual if you can't find it.
  3. Remove the seat or access panel Release the seat (usually unlocked with the ignition key) or undo the side-panel screws (4-6 mm Allen keys or Torx are common). Keep the fasteners in order so you don't lose any.
  4. Identify polarity and hold-down Find the positive terminal («+», red cable) and the negative («−», black cable). Warning: some motorcycles — especially classic Japanese models — use reverse polarity; always confirm the exact orientation before removing the battery. Check whether it is held by a strap, clamp or plate.
  5. Disconnect the negative terminal first Using an 8-10 mm wrench, loosen and disconnect the negative terminal. Move it far enough from the chassis and secure it so it can't touch accidentally while you work.
  6. Disconnect the positive terminal Remove the positive protective cap if present and disconnect that terminal. Move the cable aside carefully and shield the area to avoid short circuits.
  7. Remove the old battery Undo the strap or hold-down. Lift the battery out keeping it upright; it weighs 2-8 kg depending on type. If it is an old flooded battery, be extra careful not to spill acid.
  8. Install the new battery and connect the terminals Fit the new battery matching the original polarity. If it is an AGM delivered dry, follow the manufacturer's instructions to activate it with electrolyte before installing. Connect positive first, then negative, and tighten gently — don't overtorque, the screws can break.
  9. Refit panels and verify Reattach the panel and seat. Without holding the starter button for more than 5 seconds at a time, start the bike and check lights, indicators, horn and instrument cluster. Reset the clock and any lost settings.

General reference guide: always consult your vehicle manufacturer's manual before following these steps, as procedures may vary or not be suitable depending on model, year and equipment. If in doubt, consult a professional. baterias.com accepts no liability for damage resulting from an incorrect procedure.
