Description

Keep your mobility equipment powered with the U1 UB12350 12V 35 Ah AGM battery from Universal Battery.


This high-quality sealed lead-acid battery is designed for reliability, long service life, and consistent performance in a wide range of mobility devices and equipment.

The UB12350 uses AGM technology for spill-proof, maintenance-free operation. Its durable construction and secure post terminals make it an excellent choice for anyone needing dependable power for U1-size battery applications. Most mobility scooters and power chairs use two 12-volt batteries wired together, and the UB12350 offers strong performance at an economical price.

AGM construction absorbs the electrolyte into a fine fiberglass mat, allowing safe shipment by air or ground with no hazardous material restrictions. With a higher 35 Ah capacity compared to many gel batteries of the same size, this battery delivers excellent runtime and value.

This battery includes the L-shaped post terminals shown in the product images.

Compatibility:
The UB12350 replaces standard 35 Ah U1 batteries, including models such as:

BP35-12H, BP35-12S, BP35-12F, SLA-12V-35AH-T3, DURDC12-35J, 12V33Ah/10HR, BT33-12HC, BT35-12HC, ML35-12 SLA, ES33-12, MU-1 SLD A, MU-1 SLD M, PC33-12, PC33-12M, PS12-35-D, PS-12350, 33-12, 33-12FP, SP12-35 NB, TD35-12, AB12350, and others.

Replacing Golden GB148 Batteries

I just replaced the batteries in my GB148 and now it runs a lot better. The batteries were fine, fit properly, and came with new terminal screws. However, the battery case was really annoying to disassemble and reassemble. You need a really long Phillips screwdriver. Be careful not to lose the screws when they fall out. These scooters are full of examples of semi-finished engineering (including the nearly useless battery charge monitor).
