What Long does differently

All the Long batteries in our catalogue are genuine product, recently manufactured and covered by the manufacturer's warranty.

The Long 55D23R-MF within the Starting Series range

The 55D23R-MF is part of the Long Starting Series range. Choosing the right reference within the series comes down to capacity, dimensions and terminals: technology and quality are common to the whole family.

How to make it last longer

In normal daily use the alternator keeps the battery charged; if the car stands for weeks, a maintenance charge once a month prevents deep discharge. Keep the terminals clean and tight, and check that the resting voltage does not drop below 12.4 V: below that it is time to recharge.

Manufacturer's warranty

The Long 55D23R-MF comes with the manufacturer's official warranty against manufacturing defects; the exact period is stated in the brand's conditions. If it fails through a defect within the period, we replace it free of charge.
