Replacing the battery in your classic Mercedes W113 “Pagoda” can be a straightforward task, but owners sometimes notice subtle differences between original and modern replacement batteries. This article addresses a common observation regarding battery size variations and ensures you choose the right battery for your W113.
Original Battery Specifications and Modern Replacements
If you’re replacing the battery in your Mercedes W113, you might observe that the new battery, while visually similar, is slightly smaller than the original. As shown in the accompanying image, there can be a small gap between the battery case and the original battery hold-down frame. This is typically because modern replacement batteries, such as the A 002 541 87 01 26, are not exactly the same dimensions as the older batteries like the A 003 541 33 01 they supersede. The original hold-down frame was designed to perfectly fit the dimensions of the older, ancestor batteries.
Historically, Mercedes-Benz utilized VARTA batteries as original equipment in the W113 and many other models for decades. VARTA was a long-time supplier until it was acquired by Johnson Controls in the mid-2000s. Owners of classic W113s might recall original VARTA batteries, often with white cases and embossed blue VARTA lettering. Even replacement batteries with Mercedes-Benz part numbers were often manufactured by VARTA, maintaining similar case designs and internal components.
Ensuring Longevity of Your Mercedes W113 Battery
While battery technology has evolved, maintaining your Mercedes W113’s battery remains crucial for reliable operation. Using a battery tender when your classic car is not in regular use can significantly extend battery life. Consistent use of battery tenders helps maintain optimal charge levels, preventing sulfation and prolonging the lifespan of your new A 002 541 87 01 26 battery, potentially mirroring the long service life experienced with previous VARTA or Mercedes-Benz branded batteries.
In conclusion, when replacing your Mercedes W113 battery, be aware of slight size differences in modern replacements. These variations are normal and do not affect battery performance or compatibility. Focusing on quality replacement batteries and proper maintenance practices will ensure reliable starting power for your classic Mercedes-Benz W113 Pagoda for years to come.
