The Maxximus brand battery is the ultimate in performance and enhanced safety. The innovative use of aluminium envelopes combined with cellular construction has resulted in a higher capacity. Tests confirm that the battery shows up to 107% of its rated Q10 capacity on average. Maxximus also means higher safety. Continuously monitored operating temperature and voltage levels on individual cells prevent overheating of the battery and as a result prevent its destruction. It has a system protecting against full discharge of the battery and a system protecting the phone against surges.
