Customer Questions & Answers
What are the exact dimensions and weight of the SY9-12 battery, and what is included in the box?
The SY9-12 battery measures approximately 151 mm (length) x 65 mm (width) x 94 mm (height, excluding terminals) and weighs between 2.5 and 2.7 kg. The box includes only the battery, ready to install; no cables or additional accessories are supplied.
What charging requirements should I bear in mind to maximise this battery's service life?
We recommend charging the battery with a charger suitable for 12 V AGM batteries, preferably limiting the initial current to 2.7 A (0.3C). Float charge voltage should be 13.5–13.8 V and cyclic charge voltage 14.4–15.0 V at 25 °C. It is essential to avoid frequent deep discharges to extend service life.
Is there any special safety risk or consideration when installing or handling this AGM lead battery?
As a sealed AGM battery, the SY9-12 is safer than an open lead-acid battery, as it does not emit gases or liquids. It is important to install it upright, avoid short-circuiting the terminals and not expose it to high temperatures (>40 °C) or fire. It complies with safety regulations for civilian use, but it must be recycled properly.
How does this SY9-12 lead battery differ from a lithium battery of similar capacity?
Lead AGM batteries such as the SY9-12 are more affordable, more robust against short overcharges and ideal for standby applications. However, lithium batteries usually offer lower weight, higher energy density and a longer cycle life, although at a higher cost and with greater complexity. The choice depends on the specific requirements and budget.
Does this battery require regular maintenance?
No, the SY9-12 battery is maintenance-free thanks to its AGM technology and electrolyte gel.
Can this battery be used straight away when received?
Yes, the battery comes factory charged and can be used straight away without prior charging.
What devices is this battery suitable for?
It is suitable for alarms, electronic scales, electric toys, uninterruptible power supplies and other portable electronic devices.
What is the battery polarity?
The polarity is positive on the right, with the red terminal as positive and the black terminal as negative on the top.
What are the dimensions of the SY9-12 battery?
Its dimensions are 150mm long, 60mm wide and 92mm high.
