Security Brands 56-TC38 3.8 Amp 12 Volt Trickle Charger
The Security Brands 56-TC38 is a 3.8 amp smart maintenance charger designed for 12 volt batteries used around gate, access-control, and standby power systems. A weak or neglected battery can cause keypad resets, receiver trouble, short solar runtime, poor relay operation, or gate operator faults depending on the equipment. This charger helps maintain a compatible 12 volt battery at a proper charge level with microprocessor control instead of simply applying a constant charge. It is not a substitute for diagnosing a failed battery, bad solar regulator, damaged wiring, or an overloaded access system. Use it only with supported battery types and only where the site setup allows a standalone charger or maintainer.
Compatible With
- Most compatible 12 volt AGM batteries
- Most compatible 12 volt gel batteries
- Most compatible 12 volt lead-acid batteries
- Most compatible 12 volt SLA, VLA, VRLA, and wet batteries
- Security Brands and AAS access-control battery maintenance applications where a separate 12 V charger is appropriate
- Bench charging or maintenance of compatible 12 V standby batteries

Technician Note
Power-management and timer parts should be matched by voltage, load requirements, battery type, and enclosure location. Do not guess on voltage or wire a high-voltage timer into a low-voltage circuit.
Before Ordering
- Confirm the manufacturer part number and any old/new part number references.
- Match the product family and application, not just the brand name.
- Check voltage, frequency, activation method, receiver family, or battery type as applicable.
- Review the existing wiring, mounting location, and enclosure before replacing the part.
- For fire access or line-voltage work, confirm local code and use a qualified professional when required.
Professional Advisory
Access-control and power-management parts should be installed in accordance with the gate operator, access controller, local code, and site safety requirements. For high-voltage wiring, fire department access, or unsafe gate movement, use a qualified gate technician or licensed professional where required.
