You're looking at a U-shaped brass adapter that basically bites onto your battery post and lets you switch between side and top terminal configurations—it's a socket terminal adapter, model numbers BT295 and BT296, and we've been moving these for years in the automotive electrical world.

Most folks grab these when their factory terminals corrode out or they're swapping in a higher-amp alternator and need that 200-amp current rating—it handles 12 or 24 volt systems, and the U shape gives you a solid mechanical grip without any soldering or crimping nonsense.

Inside diameter runs roughly +19mm on one side, -17.5mm on the other, so you've got a bit of wiggle room depending on your battery post size—it's injection molded brass, weighs about 143 grams for a set, and (usually 2-4 weeks lead time) we keep production rolling for both positive and negative polarity.
Actually, what makes these reliable is the brass itself—it's not plated steel or cheap alloy, so you get real conductivity and high-temperature resistance that holds up under hood—we run COA on every lot, and CE certifcation is standard, but I'll be honest, they're not meant for marine saltwater environments.

Anyway, when you order, we typically ship by HS code 8536909000, and MOQ is around 50 sets or so—we've got stock most of teh time, but double-check if you need a custom inside diameter or a different plating, because the standard tooling is set for these dimnesions.
The inside diameter is +19mm for the positive terminal and -17.5mm for the negative terminal—so you get two sizes in one set.
Yes, they’re CE certified, which means they meet European safety and performance standards for electrical components.
Absolutely, we can adjust the polarity marking or tweak the U-shape dimensions. Just send us your specs and we’ll work out the details.
MOQ is usually around 500 sets for custom orders. Lead time is about 20-30 days after we finalize the design and sample approval.
Store them in a dry, cool place away from moisture and extreme temps—like a sealed container or original packaging. This prevents tarnishing and keeps the high-temp resistance intact.
