Bateria chumbo 6V 4Ah recarregável SY4-6 para alarmes, balanças e brinquedos

La bateria SY4-6 sol tenir dimensions aproximades de 70 mm d’alt, 47 mm d’ample i 101 mm de llarg, amb un pes típic entre 0,6 kg i 0,8 kg. La caixa normalment inclou només la bateria; no se subministren cables ni connectors addicionals.

La bateria SY4-6 ve precàrregada de fàbrica i es pot utilitzar directament. Per maximitzar la seva vida útil, és recomanable fer servir un carregador específic per a plom-àcid AGM a 6 V, limitant el corrent a 1,2 A (0,3C). S’aconsella evitar descàrregues profundes reiterades i recarregar la bateria dins de les 24 hores posteriors a una descàrrega. Emmagatzemeu-la sempre entre 10 °C i 25 °C.

Aquesta bateria AGM és lliure de manteniment i segellada, però s’ha de mantenir allunyada de fonts de calor superiors a 50 °C i no s’ha d’obrir ni perforar. Compleix amb normatives internacionals com IEC 60896-21/22 i està dissenyada per minimitzar el risc de fuites. Utilitzeu sempre protecció contra polaritat inversa durant la instal·lació.

Davant d’una bateria de liti equivalent, la SY4-6 ofereix un cost inicial més baix i més robustesa davant càrregues de flotació, però té menor densitat energètica, més pes i una vida útil menor (normalment 200-300 cicles vs. 500-1000 cicles en liti). Requereix espai i pes extra en aplicacions mòbils, però és preferida en sistemes estacionaris o on el cost és crític.

The SY4-6 battery usually has approximate dimensions of 70 mm high, 47 mm wide and 101 mm long, with a typical weight between 0.6 kg and 0.8 kg. The box normally includes only the battery; no cables or additional connectors are supplied.

The SY4-6 battery comes pre-charged from the factory and can be used straight away. To maximise its service life, it is recommended to use a specific charger for 6 V AGM lead-acid batteries, limiting the current to 1.2 A (0.3C). It is advisable to avoid repeated deep discharges and recharge the battery within 24 hours after discharge. Always store it between 10°C and 25°C.

This AGM battery is maintenance-free and sealed, but it must be kept away from heat sources above 50°C and must not be opened or punctured. It complies with international standards such as IEC 60896-21/22 and is designed to minimise the risk of leaks. Always use reverse-polarity protection during installation.

Compared with an equivalent lithium battery, the SY4-6 offers a lower initial cost and greater robustness with float charging, but it has lower energy density, higher weight and a shorter service life (usually 200-300 cycles versus 500-1000 cycles for lithium). It requires extra space and weight in mobile applications, but is preferred in stationary systems or where cost is critical.
