UPLUS BCI Group 140R Car Battery AGM-L50-UP - Start-Stop Power

Our review of the UPLUS BCI Group 140R AGM-L50-UP finds it best suited to drivers who need a compact, reliable start-stop battery with strong cold-weather starting and good cycle life. The single biggest reason to buy is its balance of 570 CCA cold cranking power and AGM start-stop technology in a BCI Group 140R package, which makes it an easy fit for many modern vehicles with heavy electrical loads. Installation is straightforward if your old battery matches the listed dimensions and terminal layout.

Key Features

• BCI Group 140R size: The standard BCI Group 140R dimensions make this battery an easy physical replacement for compatible vehicles when measurements match.
• AGM construction: Absorbent Glass Mat design provides maintenance-free operation and resists acid leakage for safer use and handling.
• High cold cranking amps: 570 CCA delivers reliable starting power in cold conditions for dependable engine starts.
• Enhanced cycle life: Construction using high density negative paste and enhanced alloy gives up to four times the cycling life versus conventional batteries for stop-start use.
• Reserve capacity: 80 minutes RC supports accessories and electronics during heavy electrical usage or short-trip driving.
• Local after-sales support: A three-year warranty with regional warehouses means faster response and support in the US.

Who It's For

The UPLUS AGM-L50-UP is aimed at owners of vehicles that require the BCI Group 140R (H4 LN1) footprint and those with start-stop systems, frequent short trips, or heavy accessory loads such as navigation, heated seats, and entertainment systems. It is also a good match for drivers in colder climates who want dependable starting performance from a compact battery.

Buyers who need an exact physical and terminal match should measure their existing battery before ordering; if dimensions or terminal layout differ, they should look for the specific group size that matches their vehicle. This is not intended for those who require deep-cycle marine or RV batteries beyond start-stop and cranking duties.
