Battery replacements: If your battery does not have a part number, or does not have one of the part numbers listed above, it is out of date and should be replaced. Authorized replacement agents are:
Responses are generally available within twelve hours depending on replacement agent availability. If possible, contact a replacement agent before updating your controller's firmware to avoid downtime. Current batteries are compatible with all older controller hardware.
Auto-positioning
Starting with Generation 3 batteries (see part numbers, above), all power cells have automatic positioning. Place the battery on the ground and use the Linden Lab Edit Tool to adjust the number in its object description, then re-insert the battery. The default value is -0.334. The ideal value is a function of the unit's chest depth. See Support Article 2235 for a complete guide on configuring this value.

All figures are presented under the assumption that the unit is not currently using any power. Most units require 478 W while recharging, which will increase the recharge times given above and slow the rate of degradation. See below for more details on degradation mechanics.
Degradation
Degradation is calculated with:
degradation_base = incoming_power ^ 1.1 new_capacity = old_capacity - degradation_rate * degradation_base
The value for incoming_power is calculated after deducting the unit's current usage, so high power requirements during charging will slow the degradation of the battery (as well as charging.)
Degradation stops when capacity reaches 40% of original value.

FRG Induction Charger series 4* | varies | varies |
CPD Cartouche Charger* | varies | varies |
ARC 47-9000 series | 144 kW (288 kJ every 2 seconds) | 1012352 J |
ACS CP-150 | 15 kW (150 kJ every 10 seconds) | 493969 J |
FSD series 12 wall outlets | 72 kW (14.4 kJ every 0.2 seconds) | 37514 J |

Power output from standard WCN wireless charging varies based on distance. A single WCN can produce up to 5 kW every 5 sec, resulting in a degradation_base of no more than 11719 J. For a standard unit drawing 780 W, this is further reduced to 9724 J.

WCN-based power level maintenance is strongly recommended for batteries shorter than 8 hours. Generation 4 batteries will reduce the rates for non-uRTG batteries by a factor of 10.
