Deep Cycle Buying Guide

Get more life — and choose the right battery

Lithium vs AGM

Lithium is lighter, gives ~100% usable capacity, charges faster and lasts far longer — best for regular use. AGM costs less upfront and is proven for lighter or backup duty.

Size it right

Match capacity to your daily draw. With lithium you can use nearly all the rated Ah; with AGM, plan around ~50% usable to protect its life.

Charging matters

Lithium needs a lithium-profile charger or DC-DC and pairs beautifully with solar. AGM works with standard chargers. We'll set the right charging for your setup.

Where it's used

Caravans, camper trailers, 4WDs, boat house banks and off-grid solar. Tell us your rig and we'll match the right chemistry and size.

Not sure — lithium or AGM?
