Tubular AGM batteries

Optima batteries incorporate the SPIRALCELL technology : they provide much greater power than conventional batteries and deliver strong loads over short periods of time. There are ideal for use with engine start or bow thruster applications.
Charge voltage : 13.6 V without boost / 14.4 V with boost.
Construction features lead sheets separated by fibreglass layers to retain electrolyte.
Circular-plated watertight batteries, compact, vibration-resistant and leak-proof.

Plastimo tips & tricks

HOW TO INSTALL YOUR BATTERY ON BOARD

  • Make sure that contact is cut off.
  • Disconnect the defective battery by starting first with the cable linked to the mass (negative terminal).
  • Clean battery support and terminals if necessary, with a metallic brush.
  • Install new battery.
  • Secure the battery firmly.
  • Reconnect, starting with the positive cable (usually the red one). Tighten the clips reasonably, and apply grease to the terminals.


HOW TO WINTER YOUR BATTERY AND PROLONG ITS LIFETIME

During the winter lay-off period, or during long periods of rest (over one month), disconnect your battery and then re-charge it to 100 %. Store it in a sheltered place, away from any source of heat, to avoid the plates sulphating irreversebly. A tension check and possibly a re-charge are necessary before putting the battery to use again.
