WEIZE 12V 35Ah Deep Cycle Battery Twin Pack
The WEIZE pair offers two 12V 35Ah sealed lead-acid batteries designed for deep-cycle use in mobility devices. When connected in series, these packs can deliver 24V, making them suitable as extra back-up power for compatible scooters and wheelchairs. The design emphasizes maintenance-free operation, with screws included for mounting but without a wire harness. Terminal configuration is Left Positive (+) Red and Right Negative (-) Black, which is a common setup for mobility equipment. They are described as broadly compatible with a range of devices beyond scooters, such as solar storage and emergency lighting.
These batteries provide a practical back-up option where a 24V system is needed or where two 12V packs are preferred over a single higher-voltage pack. Because they are lead-acid, weight is heavier than lithium options, and charging times can be longer. Proper ventilation and disposal considerations apply to lead-acid batteries. The bundled screws help with mounting, but verify your scooter’s mounting hardware and frame clearance before purchase.
- Includes two 12V 35Ah sealed lead-acid batteries
- 2-pack with mounting screws (wire harness not included)
- Left positive / right negative terminals
- Suitable for 24V configurations in scooters or wheelchairs

Buying Guide
Voltage And Compatibility
Match the battery voltage to your scooter’s system. 36V packs suit most M365-family scooters and other 36V boards, while 12V packs are common for older or toy-grade models. Confirm connector type, mounting space, and whether an in-series connection is needed to reach the target voltage. Inconsistent voltage or an improper connector can prevent a battery from fitting or charging correctly.
Battery Type And Safety
Li-ion and LiFePO4 offer higher energy density and lighter weight than lead-acid options, but require careful handling and a compatible BMS. A robust Battery Management System protects against overcharge, over-discharge, short circuits, and overheating. For mobility devices and scooters used outdoors, safety certifications (CE, ROHS, MSDS) indicate reliable manufacturing and safer operation.
Capacity And Range
Higher capacity (Ah) generally means longer run time, but also more weight. Real-world range depends on rider weight, terrain, wind, tire condition, and acceleration habits. If you frequently ride hills or carry extra gear, prioritize higher Ah within your scooter’s size and weight limits.
Size, Weight, And Fit
Battery dimensions must fit the available compartment or rack. Measure length, width, and height, and compare with product specs. Weight affects handling during installation and daily carrying. A slightly larger pack may offer more range but require more mounting clearance.
Installation And Maintenance
Some packs come with mounting hardware and pre-wired connectors; others require adapters or a new harness. Inspect terminal layout and ensure polarity matches your scooter’s battery compartment. For lead-acid packs, plan for venting and longer charging times. Lithium packs typically require less maintenance but demand careful charging practices and safe disposal at end of life.
Warranty And Support
A solid warranty and accessible customer support help mitigate risk when purchasing a replacement pack. Look for clear return policies and guidance on compatibility checks. Vendor reliability also matters for long-term serviceability and potential future replacements.
