AJC Battery Compatible with Leoch LP12-35 12V 35Ah UPS Battery

Our review of the AJC Battery compatible with the Leoch LP12-35 12V 35Ah UPS Battery finds it to be a straightforward, budget-conscious replacement for UPS systems that need a direct-fit, same-voltage battery. The bottom line: this AJC unit is aimed at users seeking a like-for-like swap for 12V UPS modules where capacity and terminal type must match. It delivers the expected 12V voltage and 35Ah capacity with NB terminals, so installation is typically quick for anyone familiar with UPS battery replacement, and it avoids the guesswork of mismatched specs.

Key Features

• Direct compatibility: Designed as a replacement for the Leoch LP12-35 so it fits systems that accept that form factor and spec.
• 12V voltage: The 12V output provides the same operating voltage required by many small UPS units and backup modules.
• 35Ah capacity: The 35Ah rating offers the same stored energy as the original, maintaining expected run times when paired with the same load.
• NB terminals: The specified terminal type ensures straightforward mechanical and electrical connection in compatible UPS trays and holders.
• AJC brand replacement: Marketed as a replacement by AJC, making it clear this is not an OEM Leoch part but an alternative from a known aftermarket brand.

Who It's For

This battery is suited to technicians, small business owners, and home users who need a like-for-like replacement for a Leoch LP12-35 in a UPS, telecom cabinet, or similar backup system. It is particularly useful when the priority is maintaining the original 12V/35Ah specification and the NB terminal layout without modifying connectors or mounting hardware.

Users who need a higher capacity, different terminal type, sealed gel maintenance specifics, or a branded OEM Leoch warranty should look elsewhere. This product assumes compatibility with the listed specs rather than offering enhanced performance features beyond the original.
