š 44AH C20 CAPACITY
Supplied C20 capacity: 44Ah
The C20 rating represents battery capacity measured over a 20-hour discharge test under specified conditions.
Although the REDTOP 35 has an Ah capacity rating, it is designed primarily as a high-cranking starting battery rather than a dedicated deep-cycle auxiliary battery.
ā³ 90-MINUTE RESERVE CAPACITY
Supplied reserve capacity at 25A: Approximately 90 minutes
Reserve capacity provides an indication of how long the battery can support a specified electrical load under applicable test conditions.
Actual runtime will vary depending on load, temperature, battery condition and state of charge.
š« STARTING BATTERY ā NOT A DEDICATED DEEP-CYCLE BATTERY
The Optima REDTOP 35 is designed primarily for engine-starting duties.
Its main strength is delivering high cranking current for ignition rather than repeatedly supplying deep discharges to auxiliary loads.
ā ļø IMPORTANT: Do not select the REDTOP 35 as a dedicated deep-cycle auxiliary battery unless the intended application has been confirmed as suitable. Repeated deep discharge is not its primary design purpose.
š§° MAINTENANCE-FREE OPERATION
The AGM construction means there is no routine requirement to top up electrolyte with water.
This simplifies maintenance compared with conventional serviceable flooded batteries.
