It seems that the charger must be compatible with the can bus system, is this the right charger? Do I have to buy one from the dealer? Any one has a good suggestion, thanks post #2 of 136 post #3 of 136 post #4 of 136 Pigtail to direct to battery with an inline fuse fitted in the positive line I've used a optimate 2/3 for 5 yrs without probs You really need a BMW trickle charger for aux socket as it runs via the canbus ,but the very latest optimate are now canbus circuit friendly so can be plug n play without a pigtail needed To view links or images in signatures your post count must be 10 or greater.

(see the graph below) current source is applied to the battery. When the battery accepts the 200mA at a voltage less than 13.9 volts the charger moves to "bulk charge." happen within seconds if the battery is not sulfated. Stage 2 bulk charge stage. is applied to the battery until the voltage rises to 14.4 volts. Stage 4 pulsing charge. is switched between 300mA and 3000 mA. If, during the 300mA part of the cycle the battery drops below 13.3 volts a new pulse is started. If the voltage stays above 13.3V for more than 30 minutes (verification stage) the charge isThe voltage is measured and then the voltage falls below 12.7 volts the charger returns to stage 2. 14.4 volts maximum during

when the charger is connected to a fully charged battery the charger can sometimes go into sleep mode. Dim green light flashing How to desulfate a batteryThe desulfation or rejuvenation algorithm works by detecting that the battery charge current is low even when the charge voltage is high. This can mimic a fully charged battery, so additional information is needed. This is done by increasing the voltage up to 18 volts with a small current limit. If the battery reaches that current limit without much additional voltage the charger signals that the battery is fully charged. If, however, the current limit isn't reached by 17 or 18 volts the charger signals that the battery is sulfated and automatically goes into the desulfation charge as is shown in the above diagram. desulfation is complete the charger switches into the bulk charge mode. found this very effective in rejuvenating sulfated batteries, but if the battery has lost a lot of water the battery will not have much capacity left.
