Re: Helt urladdat AGM-batteri

Vid 11,5V är det lämpligt att stoppa testet, efter det sliter du bara mer på batteriet och det ska aldrig laddas ur så långt vid verklig drift.

Det låter lågt.
För ett 92Ah (K20) batteri blir 10 timmars strömmen 92/1,15/10 = 8Ah. Det ska alltså då laddas med minst 3,2Ahttps://www.odysseybattery.com/wp-content/uploads/2020/05/ODYSSEY_Battery_Reconditioning_Charge_Procedure.pdf skrev:1. Discharge the battery using the vehicle head lights or connecting some electrical load to the battery and discharge to 10.0V under load measured with a hand-held digital volt meter. Once 10.0V is achieved, disconnect the electrical load or turn off the headlights or other electrical system or device.
2. Begin recharging with an approved charger as listed at www.odysseybattery.com and with appropriate amperage for the capacity of the battery, minimum 40% amperage of the 10 hour capacity rating of the battery. Utilizing chargers that achieve 14.7V during charge and 13.6V in float are ideal. Monitor the batteries terminal voltage with the charger operating to assure 15.0V is not exceeded at any time. Charge the battery until the charging amperage seems to be near zero amps and if the charger has a 13.6V float, float charge for 8-10 hours.
3. If the battery gets hot to the touch (exceeds 125⁰F), stop charging and allow to cool. Once cool, begin charging again until charge complete.
4. Charging times can be 6-10 hours depending on the charger amperage rating to the amp-hour rating of the battery. As an example, a 10 amp charger on an ODYSSEY PC925 would take approximately 7-8 hours to fully recharge.
5. Performing more than one discharge and recharge cycle is beneficial to increasing restored capacity.
