I have the 9 amp nimh battery, charger and 18w hid light head from a halcyon Helios 9 for sale. Battery is fairly new and still does about 3:45hous burn time. The canister I’m keeping for my heated gear. Pm me to discuss.
Have you tried to cycle charge and discharge your battery. I found that the nimh battery charger will give you the green light but battery has not really been fed enough amp hours. I have to keep the battery charging over night after green light comes on as the charge continues to trickle charge ethe battery,and these batteries need this trickle charge.
