Only the polarity: the FG1250 has the positive terminal on the right and the FG1251 the positive terminal on the left. Capacity (125 Ah), cranking power and dimensions are identical.
How much does the Fulmen FG1250 weigh?
29.5 kg, with 125 Ah of capacity. For reference, the Fulmen FF1250 (125 Ah) weighs 31 kg.
Which battery is equivalent to the Fulmen FG1250?
With the same dimensions, polarity and similar capacity you have the Exide EG1250, Tudor TG1250 and Deta DG1250. As the FG1250 is a conventional battery, an EFB or AGM of the same size also works.
Are truck batteries fitted in pairs?
Almost always, in series for 24 V. Replace them in matched pairs: mixing a new one with an old one unbalances charging and shortens the new one's life.
