Tolerates extreme temperatures well, with low self-discharge during winter shutdowns or between stays at vacation homes. ### Why this solar battery? - **Designed for solar systems** optimised for daily charge/discharge cycles - **Handles extreme temperatures** in technical rooms or outdoor installs - **Minimal self-discharge** when left idle over winter or holidays πŸ”Œ Voltage 12 V ⚑ Capacity 100 Ah C20 πŸ“ Dimensions 338Γ—170Γ—217 mm βš™οΈ Technology AGM βš–οΈ Weight 34,5 kg 🏷️ Model CWP Series ## Description ## Solar battery Long CWP100-12N CWP Series 100Ah 12V 12*V* Voltage 100*Ah* Capacity 34.50*kg* Weight For off-grid photovoltaic installations and storage systems, the **Long CWP100-12N** from the **CWP Series** range stores **100 Ah** with AGM technology through daily charge and discharge cycles. Measuring 338 Γ— 170 Γ— 217 mm, it is the direct replacement for off-grid PV systems fitted from the factory with a 100 Ah battery of this format. - AGM: faster recharging and better cycle resistance than a conventional battery. - Low self-discharge during the darker months. - Maintenance-free in off-grid installations. - Compatible with common MPPT and PWM controllers. ### What the Long CWP100-12N is for With 100 Ah, the Long CWP100-12N stores the energy from your panels for the night and cloudy days. Check that it matches your current battery in dimensions, terminals and hold-down: this reference has a weight of 34.50 kg. ### The Long CWP100-12N: CWP Series range and AGM technology The **CWP Series** is the Long range the CWP100-12N belongs to: it shares the same construction and quality criteria with the rest of the series, and varies in capacity and format to suit each vehicle. AGM (Absorbent Glass Mat) technology seals the electrolyte in glass microfibre. The result is a maintenance-free battery that is highly vibration-resistant and able to withstand deep discharges that would ruin a classic lead-acid battery. ### Size, terminals and hold-down of the Long CWP100-12N It has external dimensions of 338 Γ— 170 Γ— 217 mm and weighs 34.50 kg. Checking the three dimensions and the terminal position before buying avoids the most common mistake when replacing a battery. ### Long: the maker behind the CWP100-12N Long (Kung Long Batteries) is one of the world's largest manufacturers of sealed VRLA batteries. Its AGM and GEL series for UPS, mobility, alarms and cycling are found in equipment worldwide as original equipment. We guarantee that every Long arrives new, charged and with the manufacturer's full warranty. ### Care and maintenance Size the installation so as not to discharge the battery more than 50% daily and set the controller to the battery technology. Charge with a charger that has an AGM mode: it limits the voltage and protects the glass-fibre separators. ### Manufacturer's warranty The Long CWP100-12N comes with the **manufacturer's official warranty** against manufacturing defects. If it fails through a defect within the warranty period, we replace it at no cost to you. ### When you get it and how to return it Same-day dispatch from our warehouse for in-stock orders placed **before [[ks:cutoff]]**: 24-48 working hours in mainland Spain and Portugal, 3 to 5 days in the islands and the rest of Europe. Returns are accepted for **[[ks:return_days]] days** if the battery has not been used (free collection on the Iberian mainland). You will receive tracking by email. ## Frequently asked questions ### Is the CWP100-12N model AGM? What does this technology offer? Yes. The CWP100-12N from Long uses AGM (Absorbent Glass Mat) technology: a sealed lead-acid battery where the electrolyte is absorbed in a glass-fibre mat. It withstands more charge/discharge cycles than a conventional one, handles heat better and is the required technology for devices with advanced Start-Stop and regenerative braking. Expected lifespan: 5-8 years under normal conditions. ### How do I change this battery step by step? In most devices it fits in 15-30 minutes with a 10 mm wrench; if the battery is under the seat or in the boot the time can double. See the step-by-step guide on this page. Quick summary: 1) switch off the engine and remove the key; 2) locate the original battery (engine bay, boot or under seat); 3) disconnect the negative (βˆ’) terminal first, then the positive (+); 4) loosen the hold-down clamp and remove the old battery; 5) fit the new one in the same orientation β€” match the polarity shown on the product sheet; 6) connect the positive (+) first, then the negative (βˆ’). On devices with Start-Stop or BMS, register the battery via OBD so the alternator applies the correct charging profile. ### How long does the Long CWP100-12N battery last? Expected lifespan of the Long CWP100-12N is 5 to 8 years in mild-climate device use with Start-Stop. In cold regions it drops slightly due to cold-start stress; in very hot regions it also drops because of electrolyte evaporation. To extend its life: avoid deep discharges (headlights on with engine off), have the alternator checked yearly, and keep the battery clean and properly secured. ### What are the measurements of the CWP100-12N model? Dimensions (length Γ— width Γ— height) are 338Γ—170Γ—217 mm β€” also written as 338x170x217 mm β€” following the European DIN standard. Always measure the space in your device before buying: even one extra millimetre can prevent the hold-down clamp from closing. The height shown includes the terminals. ### Which batteries are equivalent to the Long CWP100-12N? Directly interchangeable batteries (same dimensions, same polarity, same Ah and CCA) are the OEM equivalents from leading brands: Bosch, Tudor, Exide and, depending on the model, Banner or Yuasa. Exact equivalence depends on technology β€” an EFB cannot be replaced with a conventional battery in Start-Stop devices. See the "Equivalents" section to view recommended options at the same performance level. ## Technical team (editorial authorship) The FAQs, guides and comparisons on this site are reviewed by the baterias.com technical team β€” over 25 years of experience validating automotive batteries. β†’ https://baterias.com/gb/technical-team --- *baterias.com β€” Automotive batteries Β· 2026-10-04*
