What the Fulbat 12N18-4A is for

With 18.9 Ah, the Fulbat 12N18-4A starts ride-on mowers, tillers and garden machinery and copes with garden-engine vibration.

Dimensions, polarity and mounting

In terms of format, the Fulbat 12N18-4A measures 205 × 90 × 162 mm (length × width × height). The positive terminal on the left decides which side the cables end up on: it is the detail that causes most buying mistakes, so check it before ordering. Checking the three dimensions and the terminal position before buying avoids the most common mistake when replacing a battery.

Technology inside the Fulbat 12N18-4A

The 12N18-4A is one of the Fulbat references for this type of use; it shares the same manufacturing and quality-control criteria as the rest of the brand's catalogue.

Conventional lead-acid is the benchmark against which other technologies are compared: good cranking current, great tolerance to alternator charging and the best price per amp-hour.

How to make it last longer

Check the voltage before the first start of the season and clean the terminals. On batteries with filler caps, check the electrolyte level and top up only with distilled water.
