200 cells are in the underwater section of the magnetohydraulics complex.

Once the sonic emitter has been upgraded, Doctor 8 will give 100 regular, overcharged and max charged energy cells.

Muggy can provide 50 a day once given the 'Parts Production' upgrade.

The box that holds the cells only appears once reaching Idolized reputation with Caesar's Legion.

Extremely large numbers can be found in one of the boxes that appears during Caesar's Favor and Caesar's Hire (sometimes over 1800 can be found).

When killed, Mister Gutsies and Protectrons will have small amounts on them.

The box will be replenished randomly with energy cells, microfusion cells, and electron charge packs, providing a continuous supply of energy weapons ammunition.

Hidden Valley bunker - If the Courier gains Accepted status or higher with the Brotherhood of Steel, they will be approached by a BoS initiate telling them that they have placed recycled ammunition in a box at the bottom of the entrance stairs to the L1 area.

Percentage chance of empty casing, hull or drained cell/pack/tank This type of energy cell is superior in all properties compared to overcharged energy cells. It requires Vigilant Recycler and can only be crafted at a workbench. The only drawback is a 10% increase in weapon degradation. A drained energy cell can be recovered at a higher rate than even standard ammunition (40%, up 5% from standard).

Max charge energy cells increase weapon damage output to 1.5 times normal and have an armor-piercing effect of -10 Damage Threshold, but causes weapons to degrade at 2.5 times the normal rate and drained energy cells can only be recovered 10% of the time.ДЄdded in the Gun Runners' Arsenal add-on, the optimized energy cell causes 30% more damage, has an armor-piercing effect of -5 Damage Threshold and weighs only 60% of the weight of all other energy cells in Hardcore mode.

This is the most powerful of the energy cell variants. It increases the damage output of weapons by 25% and has a -5 Damage Threshold effect on enemies (standard energy cells give -2 to DT), but degrades weapons 50% faster than normal and only has a 25% chance to recover a drained energy cell (the normal recovery rate is 35%). This ammunition is more powerful than standard energy cells. The bulk design also means a significantly reduced chance of recovering a drained energy cell (only 20% compared to the standard 35%). The reduced charge results in only 85% of normal weapon damage and no Damage Threshold negation (standard energy cells negate 2 points), but also reduces the strain on the weapon as well, reducing weapon degradation rate to 85% of normal.

Bulk energy cells are less potent than the standard version but are cheaper to purchase.
