Hello. I have an IDX VL-2 Plus V-lock Li Ion charger and Endura batteries. When I put the batts on charge I see the solid red light (normal) and after a while it shows green (normal), the problem is the batteries have no charge on them. The user manual says if it is a battery fault the charger will flash amber when the battery is put on charge. If it is a charger fault it will flash red. It does neither. It acts normal, but the batteries don’t charge. I haven’t used them in quite a while, so, could the cells in the batts be dead or is it the charger? The charger’s 4 pin DC output is working fine

Thanks.
