Ni-MH Rechargeable Backup Batteries For Automotive T-BOX & In-Car Electronics
Automotive telematics T-BOX is the core electronic unit of intelligent connected vehicles, which requires long-lifespan backup power to retain vehicle positioning data, communication logs and fault records when main power fails. Our automotive-grade NiMH cells and customized battery packs are specially developed for vehicle T-BOX, V2X modules and a full range of onboard low-power electronics. Compared to disposable alkaline cells, NiMH reduces after-sales replacement costs for automakers; compared with lithium power sources, nickel metal hydride avoids thermal runaway risks inside sealed vehicle control boxes, fully adapting to high and low temperature fluctuations inside car cabins. Our car-spec NiMH products are supplied to mainstream vehicle telematics manufacturers, passenger car OEM factories and commercial fleet monitoring system suppliers worldwide, supporting customized voltage, size and connector schemes for mass production.
Core & Typical NiMH Application Scenarios For Intelligent Vehicle Onboard Systems
Vehicle T-BOX & V2X Telematics Terminals (Core Application)

Our low self-discharge NiMH battery packs serve as mandatory backup power for intelligent vehicle T-BOX telematics units. When the vehicle main battery is disconnected or power cut off, the NiMH pack maintains continuous GPS positioning, 4G/5G remote communication and fault data storage, avoiding loss of vehicle tracking information for fleet management and car OEM remote monitoring systems. The anti-vibration sealed structure withstands long-term bumpy road driving, while wide temperature formula stably operates in -20℃ ~ 50℃ vehicle cabin environments all year round.
Wireless Tire Pressure Monitoring Sensors (TPMS)

AA and AAA miniature NiMH cells match aftermarket wheel-mounted TPMS sensors. Ultra-low standby power loss supports months of continuous tire pressure and temperature detection, resisting extreme heat from summer road surfaces and cold winter outdoor parking, lowering maintenance frequency for logistics fleet operators.
Smart Remote Car Key Fobs & Keyless Entry Remotes

Compact micro NiMH rechargeable cells fit slim smart key shells for passenger cars and commercial vans. No memory charging effect allows users to recharge at any residual power, and low self-discharge ensures stable lock/unlock wireless signals after months of vehicle parking.
Infotainment & Navigation System Memory Backup Modules

Small-capacity NiMH backup packs retain radio presets, navigation position records and screen parameter settings for car multimedia hosts. The system will not reset repeatedly after each ignition startup when the main vehicle power supply is temporarily disconnected.
Onboard Dashboard Driving Recorders (Dash Cams)

Medium discharge NiMH packs supply emergency instantaneous power for dash cams. In sudden vehicle power failure collisions, stable flat voltage ensures complete storage of driving footage, solving data loss complaints for auto electronics aftermarket retailers.
Vehicle Emergency Warning & Breakdown Safety Lights

Sealed long-cycle NiMH cells power magnetic car emergency warning lights stored in vehicle trunks. Even after years of shelf storage, sufficient capacity remains for roadside breakdown warning without frequent replacement.
Car Door Lock & Keyless Access Control Modules

Micro NiMH cells maintain proximity sensing and wireless unlocking response speed for door access modules. It still supports normal touchless entry after long-term vehicle parking with depleted main battery.
OBD Vehicle Fault Diagnostic Scanners & Portable Inspection Tools
Standard AA NiMH cells power portable OBD fault detectors used in auto repair workshops. Hundreds of recharge cycles cut long-term procurement costs for maintenance tool suppliers, and stable voltage prevents fault code reading distortion during long inspection sessions.
Portable Vehicle Emergency Backup Power Modules
Custom series combined NiMH packs form compact trunk-mounted emergency power modules, supporting temporary mobile charging, lighting and auxiliary electrical startup assistance for passenger cars and light commercial vehicles.
