How to recharge weapon with charges?

I did this:

local combat = createCombatObject()
setCombatParam(combat, COMBAT_PARAM_TYPE, COMBAT_ENERGYDAMAGE)
setCombatParam(combat, COMBAT_PARAM_DISTANCEEFFECT, CONST_ANI_ENERGY)

local function autoRechargeHandWeapon(cid)
    local itemID = 7424
    -- check hands to refill
    local hand_to_check = 0
    local left_hand = getPlayerSlotItem(cid, CONST_SLOT_LEFT)
    local right_hand = getPlayerSlotItem(cid, CONST_SLOT_RIGHT)
    if left_hand.uid ~= 0 and left_hand.itemid == itemID then
        hand_to_check = CONST_SLOT_LEFT
    elseif right_hand.uid ~= 0 and right_hand.itemid == itemID then
        hand_to_check = CONST_SLOT_RIGHT
    end
    -- check charges in hand
    local wepon_hand_charges = getPlayerSlotItem(cid, hand_to_check).type
    print("wepon_hand_charges: " .. wepon_hand_charges)
    if wepon_hand_charges <= 2 then
        -- check if there is more in backpack
        local weapon_in_backpack = getPlayerItemCount(cid, itemID)
        print("weapon_in_backpack: " .. weapon_in_backpack)
        if weapon_in_backpack > 1 then
            -- over charges weapon on hands, refil:
            addEvent (
                function ()
                    doPlayerAddItem(cid, itemID, 600)
                end, 100
            )
            addEvent (
                function ()
                    doPlayerRemoveItem(cid, itemID, 600)
                end, 150
            )
        end
    end
end

function onGetFormulaValues(cid, level, skill, attack, factor)
    min = -1
    max = -2
    return min, max
end
setCombatCallback(combat, CALLBACK_PARAM_SKILLVALUE, "onGetFormulaValues")

function onUseWeapon(cid, var)
    autoRechargeHandWeapon(cid)
    return doCombat(cid, combat, var)
end

But i got 2 problems
1- the items that is adding on hands has not 600 charges, has 100... why?
2- how to get an specific item on backpack, get it charges, remove it, and then add other with the same charges?
