43 12 V Batteries What does C100 mean when referring to the capacity of a rechargeable battery? The usable capacity of a rechargeable battery is heavily dependent on the amount of discharge current. Since the rechargeable battery is completely discharged during a measurement, a discharge over a longer period (e.g. 100 hours for C100) means that the discharge current is much lower than during a rapid discharge (e.g. 20 hours at C20; C20 always applies when no other data are provided). As a result, a rechargeable battery in an application with very low discharge current has a higher usable capacity than when the same rechargeable battery is used within a shorter timespan and thus at a higher discharge current. Special Wet Rechargeable Battery 12 Volt • extremely low self-discharge • ideal for 12 V battery units with or without solar panel • designed especially for fencing units due to its slow charge and discharge cycles • acid: sulphuric acid 37 % = density of 1.28 • supplied without acid • when not in use, the battery must be charged at least once a month • „dry pre-charged“ battery • charge completely after filling with acid • capacity data for a 100-hour standard discharge (C100) • 1-year warranty (note: warranty does not cover deep discharging) Important: for safety reasons, the batteries are supplied without battery acid. We recommend that they be filled by a professional „on site“! Ref. no.

Usable capacity = rated capacity x 0.65 2. Energy consumption of device (Ampere) = energy consumption in mA (see device type plate, e.g. 120 mA) : 1000 3. Operating period (hours) = usable capacity: energy consumption Example: 1. 88 Ah x 0.65 = 57.2 Ah 2. 120 mA : 1000 = 0.120 A 3. 57.2 Ah : 0.120 A = 476 hours (19 days)
