Hi i purchased the SLB DSE 901 starter kits i was having trouble finding anyone in the UK that stocked the spare batts and attys for the SLB so i went to TW and purchased there RN ones now i purchased 5 black and 5 silver batts i am now having trouble charging them in the chargers bought for the SLB batts it has to be the chargers as the SLB batts charge up well on them and i am certain that all 10 batteries from TW cannot be all faulty. I screw the batts in and it goes red but about 10 mins later they go green and the batteries start to flash. I then set them up have around 4 puffs then the batts start flashing to be recharged again. I have now sent for two chargers from TW to see if that is the problem. Has anyone else had any problems like this with the SLB and RN types not being compatible?
