• 1785 cycles to 80% DOD
• 7 year warranty

These heavy duty batteries are designed for unsurpassed repeated deep cycling service in renewable energy applications. Thick plate design with high density active material and increased liquid reserve. Several 2V cells are pre-assembled together to give higher voltage blocks. These in turn are connected to form a battery bank with appropriate voltage and capacity. Unique battery design features dual container construction. Removable cells are fitted with a durable case giving double protection against breakage or leakage. Easy on-site assembly with no special tools or skills requires. Supplied fully charged with inter-connectors. Self Discharge: ~2-3% per month.

• 3200 cycles to 50% DOD
• 2100 cycles to 80% DOD
• 10 year warranty

The Rolls Deep Cycle AGM battery range provide the performance and life of a true deep cycle battery with all the convenience of sealed construction and being maintenance free. They feature thick plates with a high density active material. This design allows for reserve energy to be stored deep within the battery plates and released during slow discharge. The Rolls AGM range are sealed, non hazardous, non spillable and completely maintenance free. They can be operated upright on their sides and are leak proof, shock and vibration resistant.

• 1250 cycles to 50% DOD
• 850 cycles to 80% DOD
• 5 year warranty

The Rolls AGM Series 2 batteries are an economy alternative to the red series 5. These batteries are deep cyle, sealed and maintenance free, perfect for smaller renewable energy projects.

• 2 year warranty
• 800 cycles to 50% DOD (depth of discharge)

Rolls Batteries AGM Terminal Covers to help prevent the possibility of short circuiting the batteries by insulating the terminal.

Ready-made cables for connecting batteries in series or parallel. Cables include two crimped terminal lugs.

(Rolls 5000 and Rolls Gel batteries are supplied with interlink cables included FOC)

Terminal covers protect against accidental contact & possible short circuit.

Water Miser caps recombine gases produced during charging to reduce frequency and need to top-up batteries with distilled water. Compatible with 4000, 4500 and 5000 series Rolls Batteries*.
