If we multiply this by 10 cells we get an ideal charge with 12 hours The 10A charger may force too much current and damage the cells. Here is what I gathered from my readings:ġ2V/7.2Ah safe charge requires 12 hours 600mA I don't know exactly how this automatic charger works but if we go by the formula posted earlier in this thread it looks like this scheme would charge a bit too fast. The ten cells would have their - posts connected to a common rail and the + posts connected to another common rail and these would terminate externally on the case as two insulated posts (one for each rail). After each use recharge them as soon as possible. More important with lead acid batteries: Do not leave them partially discharged for extended periods and do not discharge them fully. Provided you do not leave it at the charger for days. For instance the LTS-NP25 (PDF at ).īut for your bicycle a fixed voltage of 2.45V/cel will suffice. These will measure DC and are not that expensive, around $10. But the perfect solution is a compensated current transformer from LEM. Sensing current can be done with a resistor in the ground lead of the batteries. Besides this, the voltages are also slightly temperature dependent. 275A 6/12V Battery Charger/Engine Starter. 6/2/40/200A 6/12V Fully Automatic Battery Charger/Engine Starter. When the charging current drops to 5% of the Ah value switch over to 2.35V to trickle charge. 15A 6V/12V Fully Automatic Battery Charger. So the best and fastest way is to charge with 2.45V current limited to app. For standby use a trickle voltage of 2.35V/cell is recommended, for cyclic use 2.45V/cell is recommended. With lead acid batteries the trickle voltage depends of their use.
