Ego Power+ BA2800T 5.0Ah Battery

With EGO's rechargeable lithium battery, you'll never be caught off guard and you'll be able to use your devices longer between charges. Its patented Keep Cool technology keeps cells cool and prolongs battery life, while its patented Power Management System protects the battery from impacts that could otherwise damage it. The built-in charge gauge gives you a clear idea of the remaining charge available. The battery fully charges in 100 minutes with the standard charger and just 40 minutes with the fast charger. Both chargers are compatible with EGO Power+ batteries and devices.
