That's why we only stock the very best choice in batteries from the most respected manufacturers and all at consistently competitive prices. This 12v 50A/H dry Sealed Lead Acid battery is a perfect replacement for you mobility aid and is also safe to be taken on public transport including aeroplanes.
The capacities of lead-acid batteries are very dependent on the temperature at which the battery is operating. The Capacity is normally quoted for a temperature of 25°C however, the capacity will reduce by about 50% at -25°C and will increase to about 10% at 45°C (figure 5).
Most lead-acid batteries are constructed with the positive electrode (the anode) made from a lead-antimony alloy with lead (IV) oxide pressed into it, although batteries designed for maximum life use a lead-calcium alloy. The negative electrode (the cathode) is made from pure lead and both electrodes are immersed in sulphuric acid.
This 12v 50A/H dry Sealed Lead Acid battery is a perfect replacement for you mobility aid and is also safe to be taken on public transport including aeroplanes. Please be sure that the dimensions of your current batteries match the dimensions listed, to ensure they are compatible with your mobility aid.
It also provides almost 2x usable energy storage over lead acid batteries with the same Ah rating. The integrated battery management system (BMS) handles all charging and discharging regulation so that the battery can be charged using the same solar or grid connect chargers used for Lead Acid batteries.
Lead-acid batteries can be dangerous because they vent hydrogen and oxygen gas during operation. The following points should be remembered: Keep the electrolyte in flooded cells at the correct level with distilled water, to make good losses due to evaporation and gassing.
