Energizer CP05U Cordless Phone Battery (GP30 & GP40 equivalent)

The Energizer CP05U cordless phone battery, is also known as the GP30AAKBMU or BC-E10N. This battery can be used to replace the GP30AAK3BMX and GP30AAK3BMJ as it is supplied with a universal connector allowing it to replace a wider range of batteries: The two separate connectors are pushed onto the contact pins in the phone to replace the original single connector. This battery also replaces GP40AAKBMU, GP40AAK3BMX, GP40AAK3BMJ, Varta T301, Varta T385, Varta T388, Varta T390 As the original NiCd cells can no longer be manufactured under European law, the batteries offered will be NiMH batteries.

These will operate in the same way as the original battery and should be fully charged on receipt by putting them into the handset and leaving it on the charger base overnight. NiMH batteries are of a higher capacity than NiCd batteries, which means that they will last longer before needing to be recharged.

The Universal Connector has an individual connector on each of the leads. These connectors may be fiddly to fit on the existing telephone connection, so big fingers may need to use a pair of tweezers to successfully push the connectors into place.

TIP: Make a note of which way the coloured black and red leads fit on the existing connection before removing the battery in your telephone.
