Yuasa High performance motorbike battery YTX14H-WC 12V 12Ah (12.6Ah) (AGM maintenance-free)

The Yuasa YTX14H-WC is the performance-enhanced "High Performance" version of the widely used YTX14 standard battery. The "H" in the type designation stands for a significantly higher starting power, which is achieved by an optimised grid structure and additional plates inside. With 240 A cold start current (instead of the usual 200 A), it offers significant reserves for engines that are difficult to start, large V2 units or use at low temperatures. The suffix "WC" (Wet Charged) usually identifies it as a factory-filled and sealed variant that is ready for immediate use.

Highlights at a glance

• High performance series: Delivers up to 20% more cold starting current (240 A) than the standard YTX14, which ensures powerful cranking of the starter especially with large displacements.
• Wet Charged (WC): The battery is usually supplied factory filled, charged, and hermetically sealed, eliminating the need to handle acid packs and enabling immediate installation.
• AGM technology: Due to the electrolyte bound in the glass mat, the battery is leak-proof, extremely vibration-resistant, and maintenance-free (no need to top up water).
• Identical dimensions: Despite higher performance, it has exactly the same case (150 x 87 x 145 mm) as the standard battery and fits into the battery box without modifications.
• Cold start specialist: Ideal for vehicles also used in winter (e.g. snowmobiles, ATVs) or motorcycles with high current demands at start (ABS systems).
• Long service life: The compacted plate structure and the sulphation inhibitor ensure high cycle resistance and robustness against vibrations.

The power pack for BMW & V-Twins

The YTX14H-WC is the ideal upgrade for motorcycles that are equipped with a 12Ah/14Ah battery at the factory but struggle to start. It is particularly popular with riders of the BMW R1200 GS (LC), large Honda V-Twins (VTX 1300, Shadow 1100), Aprilia Dorsoduro/Shiver or various Piaggio maxi scooters. It often eliminates the problem of the "tired starter" after cold nights.

FAQs for Yuasa YTX14H-WC

What is the difference from the standard YTX14-BS?

The only difference is in the performance, not in the size.

• YTX14-BS (standard): approx. 200 A starting current.
• YTX14H-WC (High Performance): approx. 240 A starting current. The H version has more lead plates in the same space. It is slightly heavier, but starts the engine much more vigorously.

Can I install this battery flat?

As the "WC" version is a factory-sealed VRLA battery (AGM), it is leak-proof. Many manufacturers allow installation lying flat up to a certain angle. As the mat completely binds the acid, the risk of leakage is minimised as long as the case is undamaged.

Do I have to recharge the battery?

Although "Wet Charged" batteries are supplied charged, they can lose voltage during storage. Measure the voltage before installation: If it is below 12.6 V, you should fully charge the battery once with a suitable motorcycle charger (AGM-capable) to guarantee maximum service life.
