In order to prolong the life of your THOMSON VM40 replacement battery please read the following:
Your THOMSON VM40 battery is charged during production in order to test it. Your THOMSON VM40 rechargeable battery will discharge between the end of the production and the moment you receive it. That is why your THOMSON VM40 battery will have to be charged before you use it. You can use your existing charger or an external charger this will optimize charging of your THOMSON VM40 battery and prolong the life of your camera power supply.
Your THOMSON VM40 rechargeable battery discharges slowly and progressively when not in use. The self discharge rate is about 1% of the battery's capacity per day at room temperature. The higher the temperature, the faster your VM40 battery will discharge. If you intend to leave your THOMSON VM40 battery for a prolonged period without use then a service charge is recommended from time to time, taking in to account the self discharge rate and time between using your THOMSON VM40 battery.
Rather than supplying original THOMSON VM40 batteries, we supply replacement VM40 batteries made by Uniross and Hahnel. Our VM40 batteries have a two year warranty, represent excellent value and meet or exceed the original specifications. We also offer free delivery on all our products including the VM40 battery.
