Share the start behavior and discharge history
Say whether the engine cranks slowly, clicks, or has no electrical response, and whether a jump helps. Note whether the battery went flat after sitting or during repeated short trips. A worn battery, loose connection, alternator fault, or key-off draw can look similar.
If a battery installed recently has already discharged, the cause should be checked before replacing it again. Do not handle a swollen, leaking, or unusually hot case. Report the condition and do not attempt a jump until the hazard has been assessed.
Confirm the specification and work area
The right size, terminal position, chemistry, and capacity depend on the vehicle’s engine and equipment. Some models use AGM batteries or require registration after installation. Send year, make, model, engine, and a label photo if it can be viewed without removing covers.
If the vehicle is at a warehouse or managed yard, reserve a safe place away from loading traffic and confirm permission. Tell us if the battery is mounted in the trunk or under a seat. Safe hood or panel access must be available before dispatch.
Test before approving a replacement
Provide jump-start dates, battery invoices, warning lights, and whether the vehicle can remain parked. Do not disconnect power to inspect the label; that can affect memory or security functions. Hye Tech confirms fitment and availability before scheduling.
The standard diagnostic/service visit starts at $149 for the mobile visit and up to the first hour of initial testing. Battery cost and any charging repair are separate. Findings and added work are explained for approval before proceeding.
