Five ways to extend the life of your lead acid battery. Part I
Sulphation: Lead and lead-dioxide react with sulphuric acid to form lead sulphate – small crystals which easily reforms back to lead, lead-dioxide and sulphuric acid. After time, some lead sulphate does not revert, but forms a stable crystalline coating which no longer dissolves on recharging. Sulphation can be reduced if a battery is fully re-charged …

What happens when a lead acid battery is fully discharged
When a lead battery sits below 50% state of charge (about 12.10v for a 12v deep cycle battery), the rate of growth & accumulation of lead sulphate crystals increases substantially. These crystals block access & availability to the plates for the electrolyte, this diminishes battery capacity. The battery has no doubt taken some damage that cannot typically be 100% reversed, but just use …
BU-706: Summary of Do''s and Don''ts
The unit mAhrs refers to how long the fully charged battery at 3.7 V dc is able to deliver 900, or 1200 milliamps, so 1.2 Amperes for an hour, before becoming fully discharged. The old one could only average 0.9 Amperes over the hour. It refers to the capability of the battery to deliver power. As long as that power is delivered at the rated voltage of your device; 3.7 V dc in this instance ...

Sealed lead-acid batteries can ensure high peak currents but you should avoid full discharges all the way to zero. The best recommendation is to charge after every use to ensure that a full discharge doesn''t happen accidently.
Lead Acid Battery Explained
In a fully charged lead-acid battery, the electrolyte is approximately 25% sulfuric acid and 75% water. The separator is used to electrically isolate the positive and negative electrodes. If the electrodes are allowed to come in contact, the cell will short-circuit and become useless because both electrodes would be at the same potential.
