• Question : Can two of these batteries charge in series on a gate opener made for lead-acid batteries?
  Answer : For an in-series (end to end 24v) circuit, twin batteries of equal AH rating usually do fine/discharge equally, as long as they are recharged equally. Uneven recharge is usually the culprit for developing an imbalance. This can be reduced by recharging them individually/not in series to equal levels.
