SuperCharge SMFN70ZZLX 765CCA 12V SilverPlus Battery

The SuperCharge SMFN70ZZLX is a sealed SilverPlus battery in the N70 case, sold for SUVs and 4WDs and rated at 765 cold cranking amps.

Inside are lead calcium plates that SuperCharge calls Tropicalised Power Plates, joined with hardened alloys and intercell connections. A hydrometer eye sits in the lid for a quick look at the battery.

Problems it solves

• A diesel that turns over slowly on a frosty morning. You get 765 CCA to spin the starter.
• Lights or a camp fridge running with the engine off. With 85Ah on board, the reserve rating sits at 165 minutes.
• Cell caps and distilled water. Being fully sealed, it has neither.

Fitment and compatibility

Measure the tray first. The case is 304 mm long, 173 mm wide and 203 mm high, and the posts need 224 mm of clearance. Assembly C decides which corner the positive sits in, so match it to the battery coming out.

Still unsure? Bring the old battery to Albion Park Rail or South Nowra and we will put it beside an SMFN70ZZLX for you.

What is in the box

One SMFN70ZZLX battery.

Install notes

Take a photo of the leads before you undo anything. The front ledge gives the hold down something to bite on, so tighten it until the battery cannot shift on a corrugated road.

Warranty

This comes with the manufacturer's warranty through the Australian distributor. See the manufacturer's terms for details, plus our guarantees under the Australian Consumer Law.

SMFN70ZZLX FAQs

How do I swap my old battery for the SMFN70ZZLX and connect it?

Negative off first, then positive. Lift the old battery out, fit the new one the same way round, positive on, negative on last, and clamp it firmly.

Does the sealed SMFN70ZZLX ever need its cells topped up?

No. SuperCharge builds it fully sealed with calcium plates, so there are no cell caps to open.

Does SuperCharge sell the SMFN70ZZLX for 4WD use?

Yes. SuperCharge sells it as an SUV and 4WD battery. Check that your tray takes an N70 case and that the old battery is assembly C before you buy.
