Maintenance-free lead batteries Panasonic will surprise by their lifetime


When observing basic rules will the top quality AGM VRLA batteries last you up to 15 years – we will advise how.

This description could start by a long list of technical improvements of Panasonic batteries. thanks to which they gained a stable place on the top of development in this segment (AGM, expanded positive grid. additives for regeneration from a deep discharge, self-extinguishing container material,…).

However those are things, which can be easily checked up from available internet source or even better from satisfied users. Instead of it, we better bring you a few advices for usage of VRLA/ SLA batteries to serve you as long as possible:

● batteries can be recharged by several ways, but one of the most reliable belongs a „constant voltage/ limited current“ method, i.e. observing max. 2.45V/ cell and a current limitation. It responds 14.7V at 12V battery and a max. current of 0.4CA. This is suitable at so called cycle usage.

● at a stable connection to a voltage source, a voltage per cell shouldn´t exceed 2.3V what is 13.8V at 12V battery. Current limitation should be set to 0.15CA.

● battery lifetime grows significantly with a decreasing temperature, i.e. it is very important to place a battery far from heat sources (transformer,…)

number of cycles (thus a battery lifetime) is very strongly dependent on a level of discharge before consequent recharging. Dependence is so strong, that for example at discharging to 50% a standard battery will reach a lifetime of approx.
