Best dressed battery

The Sealed Maintenance-Free (SMF) battery’s popularity is still strong and ACDelco says they’re reputation is based on three key features. The first being the fact that you can fit and forget – the units are maintenance-free after all, the second is extended service life thanks to the lead/calcium expanded grid design. Lastly, increased shelf life is offered by the SMF – it can be stored for up to 12 months without the need for charging and being a distress purchase product, stocks will always need to be at the ready.

Lead calcium technology resists corrosion, overcharging, water usage, amongst other unhelpful things wehich will limit a battery’s life.

ACDelco’s Platinum range of SMF batteries provides all makes coverage of cars, LCVs and some CVs. Most have a built-in hydrometer to show state of charge and are sealed to protect against acid damage. The units also feature heat-sealed covers and low resistance envelope separators to prevent shorting.
