Answers before you buy
Dimensions and weight of this model?
Measurements are 242 × 175 × 190 mm, and it weighs 17.9 kg. Check the height under the bonnet or seat as well.
Is this enough battery for a cold start?
Rated 680A for cold starts and 62Ah in capacity, it will suit engines whose manufacturer specifies equal or lower values. Big diesels in cold climates benefit from extra margin.
Can I connect several of these in series or parallel?
It is rated 12V and 62Ah. Check your equipment's voltage first: a mismatch can damage electronics or simply not work.
How AGM batteries work and how to look after them
Open up an AGM battery in your imagination and you would find the acid soaked into thin glass-fibre sheets squeezed against each plate. Because nothing can spill, AGM batteries can live inside a cabin, a boot or under a seat. If the original was AGM, the replacement should be AGM too.
