Deep Discharge

REBATT UK can offer the re-conditioning service on batteries every 120 cycles or every 3 months. The price is £ 2.00 / battery pack plus p+p. Optimum results are achieved when nickel-based batteries are reconditioned from NEW.

The discharge is taken down to 0.2v per cell which is deemed to be the voltage rating needed to remove the crystalline formation from the cell pack before been recharged again. Usually this process can be successful on the first attempt, however, if the 80% target capacity is not achieved the battery analyzer will repeat the process.

Memory Effect – This adverse condition occurs when the battery cells are only partially discharged many times therefore a periodic full discharge is so important that “if forgotten” large crystals will; form on the cell plates [referred to as memory effect]

The crystalline build – up reduces working capacity and the battery pack will eventually lose its performance if below the 80% needed before been recharged again very quickly. To prevent memory effect the user should occasionally [every 120 cycles] fully discharge the battery down to 0.1volts per cell to remove the crystalline formation from the cell plates.
