Tutoriels techniques, guides d'achat et tableaux de références croisées pour les batteries au plomb-acide et AGM. AGM vs inondée, dimensionnement par temps froid, décodage de groupe BCI, références croisées JIS / DIN.
Buyer's guide
AGM batteries handle modern start-stop and high-accessory loads better than flooded; flooded chemistry is still the right call for older standard vehicles. Here's how to tell which one your car needs.
Canadian winter guide
Cold cuts cranking amps in half and drains stored capacity. Here's what CCA rating to look for, what to expect at −30 °C, and how to keep a battery healthy through a Canadian winter.
How to read group sizes
BCI Group 65, 47/H5, 51R — the codes feel arbitrary but every digit means something. Here's the system, and how to read your current battery's case before you order a replacement.
Technical primer
CCA is what starts your engine in winter; RC is what runs your stereo when the engine is off. Here's how to read both numbers and what trade-offs the bigger ones imply.
Cross-reference chart
Japanese makes use JIS group codes (D23, D26, B20); Europeans use DIN (L2, L5, LB3). Here's how those map to the BCI numbers North American dealers stock, with practical examples by make.
D'autres articles seront publiés au cours de la semaine 6 + du mois 2 — le tableau JIS-vers-BCI est conçu pour s'étendre à mesure que nous ajoutons des pages par marque, et les guides d'achat recevront une expansion plus approfondie sur l'hiver canadien parallèlement à la couverture du corridor par temps froid au T4.
