Mighty Max Battery12V 5Ah F2 SLA Replacement Battery for Leoch DJW12-4.5

Perfect replacement battery for APC BE425M. Easy to install and works great.

I got this battery for a small UPS unit. The price is great and it seems to be working perfectly although it’s only been a few days.

No problem installing into unit. A bit of a bonus, 1/2 amp hour more.

Advertised as an F2 terminal battery. What I got was an F1 battery with cheap little adapters. If I was ok with the adapters I would have just bought a cheaper F1 battery in the first place.

Seller suggested rather than a return they send an adapter to “make it fit”! Adapter never received and now I cannot return the battery (window for return expired). Since this is a backup for a garage door, I purchased a replacement that fits perfectly it I’m left with a brand new, totally unusable battery. Very disappointed!!

The battery resolved my APC UPS from constantly cycling. The original battery was just over 3 years old and started showing signs of failing about 6 months ago with a couple of UPS resets each month until last week, and it would not reset with even the smallest load.Installation: There are four screws on the case and a connector on each terminal to remove the battery, so removal and installation was a breeze. The terminals were type F2 as the original although a bit thinner metal than the original terminals, I snugged up the wire connector with my needle nose plyers for a tight connection. I rate this a 3 out of 10 difficulty level as the hardest part was removing the all-important "safety disconnect plug" on the bottom, and finding a screw I dropped on the carpet, a slippery little sucker (as Julia Roberts once said).Great Savings: The UPS replacement cost would have been around $60, so I am convinced this $17 battery was an economical and "Eco-Friendly" repair that anyone should try versus replacement.Finding Help: I recommend first understanding what you are getting into with safety, and ordering the correct battery. I searched YouTube and found a relevant repair video with the exact APC model, and this helped give me the confidence needed. I also learned from their honest mistake and ordered the correct battery with F2 connectors, as they come with ether F1 (Narrower) and F2 (slightly wider). Proper size is important to ensure OEM fit to the original wire connectors. I expect that your brand, and model will likely vary a bit depending on the design and amperage capacity of the unit. Safely open the unit and read the label on the battery, the part number will likely reveal the proper connection specifications.
