Interstate SLA1165 12V 55Ah AGM Battery Pair

This listing is for two Interstate SLA1165 sealed AGM batteries, each rated 12V and 55Ah. The product information describes the model for both standby and cyclic applications. Those terms refer to different operating patterns, so use the battery only where its specifications match the equipment manufacturer's requirements. The pair is supplied as batteries; the listing does not identify a prewired pack or a particular terminal arrangement.

Keep the Per-Battery Rating Clear

Each battery is rated 12V and 55Ah. The equipment's wiring determines whether the pair supplies a different system voltage or changes available capacity, so do not treat the two labels as one combined pack specification. Check the required battery count and the original wiring diagram before ordering, and preserve the equipment's specified connection arrangement during replacement.

Check Physical and Electrical Compatibility

Compare the SLA1165 model number with the installed battery labels and the equipment manual. Confirm the battery tray dimensions, cable reach, terminal style and orientation; the listing does not provide enough terminal detail to assume a connector type. Also verify that the device and charger are designed for sealed AGM batteries with this voltage and capacity. A battery may have the right nominal voltage yet still differ in fit, terminals or charging requirements.

Replace as a Matched Set

If the equipment uses the two batteries together, replacing the pair at the same time helps avoid mixing different models, capacities or service histories. Follow the manufacturer's instructions for battery handling, wiring and charging. If the current labels or wiring do not clearly match the SLA1165, pause and confirm the required model and terminal configuration with the equipment maker or a qualified service provider rather than adapting the connections.
