Compared to flooded batteries AGM batteries are dry celled with the positive and negative plates separated by an absorbent glass mat that holds the electrolyte like a sponge. This minimises electrolyte spillage. OPTIMA AGM batteries use a higher purity of lead compared to other AGM batteries on the market, this extends battery life and increases performance for example; superior starting power, the ability to recharge much faster, higher charge acceptance and shock/vibration resistant. Optima Batteries can be used in a vast range of applications from industrial, agricultural, commercial, marine, auto, ICE, mobility and golf with their easy recognisable colour coded ranges:
