kungfumonkey Posted September 25, 2012 Share Posted September 25, 2012 hey guys just quick question but how long should i charge my 9.6v 1600mah crane stock batts for on there first charge as dont wanna under charge them damage them etc or does it not matter aslong as they dont get over 60 degrees? i have a fast/trickle charger - http://www.component-shop.co.uk/html/jlc002as.html and these are the batts i have - http://www.component-shop.co.uk/html/8vp1600afp-ll.html any help is much appreciated Link to comment Share on other sites More sharing options...

The charger goes to trickle charge once it senses the battery has charged so you are unlikely to damage it if you leave it on a bit too long - would not leasve it all day though!

RR01 Posted September 25, 2012 Share Posted September 25, 2012 lol im a complete tard at times cheers for that mate good job u said sum,thing as all i cld find online was charge it for 12 hours from new lol The time you saw online was probably for a lower mA charger rate. 1000mA is a fairly high charge rate for a Nihm battery. Charging lower and slower will actually make the battery retain the charge for longer. The normal equasion for battery charging is: mAh of battery x 1.5 / charge rate in mA. So example: 1600mAh x 1.5 = 2400. 2400 / 500mA = 4.8 hours or 4 hours 48 mins. This is assuming the battery is run down to it's notional voltage (i.e. 9.6V in your case) or lower. If the battery was showing about 10.3V on a volt meter then you could drop the charge time to about 3 hours. Although your battery says 9.6V, when fully charged it will show about 11.3V on a volt meter if the battery is in good condition. Link to comment Share on other sites More sharing options...

Supporters Richard65 Posted September 26, 2012 Supporters Share Posted September 26, 2012 Your charge sounds fine. The charger shows a green light when the battery is fully charged and automatically switches to a trickle charge so it will not damage the battery.

Supporters Richard65 Posted September 26, 2012 Supporters Share Posted September 26, 2012 I think the main point he was making was thatb the 12 hour charge time waqs incorrect and that it should be 2-3 hours. The charger you bought is quite a fast charger for the 1600 batteries and he was just pointing out that a slower charger might be better for a longerlife of the battery. With the 1600 battery you would probably need a spare for a full day of skirmishing or charge up in the breaks using the sites chargers (they will be fast chargers).
