Battery Tender Jr strange behaviour

[Mover]

Hi,

I've had a Battery Tender Jr for about 5 years that the Venture is plugged into when not in use. Recently when first plugging into the electrical outlet the light will flash green very rapidly. That might last for about 10-15 seconds then it will slow back down to the usually alternating red and green until it goes to steady green. I checked the connections at the battery and they are tight. I haven't found any info on the Deltran website to indicate what this rapid green flashing might be so thought I'd ask here.

Thanks

GREEN LIGHT FLASHING – When the green light is flashing, the battery

is greater than 80% charged. For BT Plus models the red light will also be

on steady. (Note: Does not apply to the 8V Plus or the 6V Junior).

This flashing I've seen because I've used the BT Jr continuously for almost 5 years however what I'm experiencing is a extremely rapid flashing that has only started to occur recently. Thanks though.
