Frequently Asked Questions

What applications are 2V long life batteries designed for?

2V long life batteries are engineered for telecom base stations, UPS systems, solar and wind energy storage and other critical installations that require more than a decade of reliable standby power.

Why do 2V cells last longer than 12V monobloc batteries?

A 2V cell is an independent single-cell unit with thicker plates, more active material and a larger electrolyte reserve, so it ages more evenly across the string and delivers a longer float and cycle life than multi-cell 12V blocks.

What is the difference between the 10hr and 20hr capacity rates?

Capacity depends on discharge time. A 10hr rating draws more current than a 20hr rating, so the same battery shows fewer Ah at 10hr. Always size the system with the rate that matches the actual discharge profile.

What should be considered when connecting 2V cells in series?

Use cells of the same model, capacity and age in one string, keep cable resistance equal between cells, and check string voltage and individual cell voltages periodically to prevent imbalance from shortening service life.

How long is the design float life of these batteries?

Under proper float charging at 20-25 °C with a quality charger, 2V long life AGM and GEL batteries are typically designed for 15-20 years of standby service, depending on ambient temperature and cycling depth.
