a few queries of the Nikon L4 battery charger

[perfection]

Question 1 - How long on an average do batteries take to refresh (discharge)

in this charger?

 

Question 2 - What does a quicj orage blinking light indicate on the charge

function?

 

Question 3 - Can i charge Ni MH cells of a slightly higher MAmp rating with

this charger ? The cells given with the L4 ae rated as 2000 mAmp but the

spare ones i bought are rated 2500 mAmp - any problems here

 

Thanks

Answer No.1 This is a hard question to answer. All depends on the charger you have. In general a fully discharged battery would take about 14 or so hours to charge if using a "common" cheap charger supplied with battery. The more expensive chargers can do it in 1 to 3 hours. There should be some numbers on the back of your charger indicating the current in mA. Most cheap charger charge at about 1 tenth or 0.1 times the rating of your battery. That is to say if you have a 2000 mMr battery it should would require a charger of about 200 mA to charge in 14 or so hours. The relationship of time and current is linear. Partially discharged batteries require diffrent times. It is best always to use the equipment until the battey symbol indicats empty and then charge. Keep an eye on your battery and make sure that they do not get "too hot to touch" while reaching the end of their charge. The more expensive chargers look at the voltage while charging and cut off when a peak voltage is reached.

 

Question No.2 Check your manual if possible.

 

Question No.3 Yes you can but as indidicated in Q1 you have to charge longer about factor of 1.25 (ratio of 25 to 20). Again don't let the battery overheat. If you do there is a chanch of poping their seals, leaking fluid and loss of capacity!
