The Hama CGA-S007E is a direct replacement battery for the Panasonic type CGA-S007. The power output of the battery is 3.7v 800m Ah & offers equivalent power of the official battery at a snip of the original price. Lithium Ion batteries have no memory effect & therefore do not need to be discharged. Lithium cells generally hold the initial charge & can be left for weeks before needing a recharge. Only the most modern battery technology is used in hama Lithium Ion batteries. They are environmentally friendly, feature a very high energy density & have no memory effect. The batteries are much smaller & lighter than any other rechargeable battery with similar capacity. All batteries are produced to the highest quality standards. A built-in microprocessor safeguards the cells by limiting maximum voltage & by protecting against deep discharge, short circuit & overload. The Hama HL-007 type battery is rechargeable & recyclable over 600 times.
