Hi, i have two NiMh batteries; a 9.6v at 1500mah and a 8.4v at 1100mah. Both are fully charged says my voltage meter; but as soon as i use any of the two in my gun they don't have the power to pull the spring back. I know my gun works because as soon as i use my friends battery my gun works. I use two standard chargers to charge the two. I calculated how long to charge them and unplugged the batteries from the chargers when the time was up to take them off. I have used both batteries in multiple games before and only now they do not work. I search around the internet and cant find any answers. Please help, i need to know if i can fix my problem or trash the batteries.
