1. lon Li lon cells have a high energy density This minimises battery size and weight It is a low maintenance battery the re is no memory effect and no scheduled cycling is required to prolong the battery s life In addition the self discharge is less than half that compared to NiCd The batteries have a lifetime of about 3 years from manufacture This is caused by internal oxidation which is hastened at high temperatures The Li lon batteries supplied by Leica Geosystems have a protection circuit to maintain safe operation limits the peak voltage of each cell during charge and prevents the cell voltage from dropping too low on discharge In addition the cell tempe rature is monitored to prevent temperature extremes GEB211 GEB221 2 2 Condition when delivered NiCd For safety reasons the batteries are only dispatched from the factory in a discharged state In this way in the case of misuse or damage to the battery hazardous conditions or physical damage caused by a large amount of stored energy are prevented NiMH For safety reasons damage free storage and shipment the batteries are dispatched with a minimal quantity of energy NiMH batteries must not be stored in a discharged state The batteries should therefore be fully charged as soon as possi ble once received Li lon For safety reasons damage free storage and shipment the batteries are dispatched with a minimal quantity of energy 2 3 Charging the batt2. performed automatically This compensates for the self discharge of the batteries that occurs for technical reasons The batteries are thus always available with full capacity The trickle charging feature only activates for NiCd and NiMH batteries as Li lon batteries only have a very small discharge when not in use Refresh function If the capacity of a NiCd or NiMH battery drops noticeably it is recommended to subject the battery to the refresh function 2 to 3 times The refresh function comprises a full discharge of the battery with subsequent quick charging Further information can be found in the user manual of the GKL221 The memory effect of batteries is explained in Section 2 8 Battery Adapter The GKL221 charger is supplied with two battery adapters Using the charger in combination with the battery adapters the following batteries can be connected to the charger Battery adapter Rechargeable batteries GKL221 with Up to four Li lon batteries and two GDI221 one battery with 5 pole socket GKL221 with one GDI221 amp one GDI222 Up to two Li lon batteries one camcorder type battery and two batteries with 5 pole sockets GKL221 with two GDI222 Up to two camcorder type batteries and three batteries with 5 pole sockets 1 3 Normal Charger GKL22 The GKL22 is a simple low cost normal charger 14 hour charger for charging NiCd and NiMH batteries It is available in the GKL22 EU and GKL22 1 US mai

7. eries New and stored batteries New NiCd and NiMH batteries reach their maximum capacity only after a few charging and discharging cycles The batteries should be fully discharged and charged three to five times NiMH batteries that have been stored and not used for an extended period more than a month should be refreshed simularly For Li lon batteries a single discharging and charging cycle is sufficient The easiest way to perform this cycling is by using the GKL221 Charging Station which has a discharge function Al ternatively the batteries can be charged and then placed in the related survey equipment during normal use and dischar ged until the equipment switches off Batteries in regular use After use the battery can be placed in the charger until fully charged the green light flashes The charging time de pends on the battery capacity and temperature An indication of charging times is shown on Page 3 2 4 Charging temperature The charging temperature ambient temperature has a significant impact on the life of the batteries Charging at high temperature can cause loss of capacity These losses in capacity are irreversible Even with several charging and discharging cycles the original capacity can no longer be ob tained For optimal charging we recommend that the batteries be charged at ambient temperatures as low as possible 10 C to 20 C 50 F to 68 F The permitted tem perature range in whic

9. ies fail prematurely A pos sibly defective cell must never be replaced in a battery pack The cells in a battery pack are all from the same manufacturing batch and thus have the same manufacturing tolerances If new and old cells are mixed the weaker old cells in the battery pack are more heavily loaded and further failures inevitable For this reason the entire battery pack is always replaced in Leica Geosystems service centres The Li lon and camcorder type batteries are in sealed housings and the cells cannot be replaced 2 11 Life The life of batteries is primarily defined by the following factors e Electrical loading e Charging method e Temperatures on charging discharging and storage e Quality of the cells Losses in capacity caused by incorrect charging are practically excluded with the Leica Geosystems chargers which have special switch off criteria to protect the battery Reduction in battery capacity is normally due to age However it can also be the result of storage at excessively low or high temperatures see Section 2 6 The suppliers who provide batteries to Leica Geosystems are among the leading manufacturers of batteries and guarantee good quality 2 12 Protecting the environ ment disposal For reasons of environmental protection and safety used or defective batteries must not be thrown away They must be correctly disposed of in a discharged state Follow the national regulations on disposal 2 13 Safe

12. power to surveying equipment forms one of the most important preconditions for all surveying tasks in the field It is a basic precondition for the function of the equipment and a key factor for reliable malfunction free operation in all environmental conditions For batteries to have a long service life retain their performance and operate without malfunctions they must be correctly maintained stored charged and discharged Incorrect handling of batteries and chargers can lead to malfunctions or premature loss of capacity of the batteries This product information summarises the most important and useful information on the chargers and batteries for Leica Geosystems surveying instruments and surveying systems 1 Chargers 1 1 Charging technology Leica Geosystems currently provides quick chargers as a matter of preference accelerated charging These charge the batteries in a correspondingly short time They ensure thanks to the latest charging technology appropriate charging and therefore the long life of the batteries Our chargers are divided into two product lines The Professional Series for the highest of demands and functionality and the Basic Series as a simple low cost alternative For batteries with 5 pin charging sockets a simple low cost normal charger with reduced functionality is still offered 1 2 Professional Charging Station GKL221 The GKL221 is an intelligent charging station with advanced charging
