walshie Posted August 5, 2012 Report Share Posted August 5, 2012 I need help deciding what battery to get for my lamp. My mate has a 12v 7Ah one and that seems fine, but I don't understand the 7Ah bit. Would a 10Ah just last longer or would it blow the lamp up? Is it just a case of finding the happy medium between weight and power? Also can these batteries be charged with either a motorbike charger or a trickle charger, or do I need to buy a specific charger? Thanks.

steve_b_wales Posted August 5, 2012 Report Share Posted August 5, 2012 The bigger the AH, the longer the battery will last. I have a few batteries, but my main one is a 12v/12amp hour. This is excellent for general use. I also use an 18amp/hour one,but the battery is a lot heavier. You can use a car charger to re-charge them, but I use trickle chargers to keep them topped up. These cost as little as £5.00. Quote Link to comment Share on other sites More sharing options...

kent Posted August 8, 2012 Report Share Posted August 8, 2012 when i started lamping there was no such thing as gunlights and the battery of choice was a lead acid motorbike one (carried in a cheap canvass rucksack), it still burned your coats etc and i once ruined a kitchen floor during changing. now we have the Lithium Ion seled units that weigh a fraction, take re-charging well and dont ever leak. To my mind you gan get a fair bit of lamping time out of one of the smaller ones if your lamp aint a real stubble burner and two makes a heck of a long night out and can still be carried easily on a belt pouch no less!. Battery MUST MATCH THE LAMP so if you feel you must have a gizzilion candle power your gunna need lug a big old battery to to keep it lit Quote Link to comment Share on other sites More sharing options...

walshie Posted August 8, 2012 Author Report Share Posted August 8, 2012 Thanks for the replies guys. i actually have a dedicated motorbike charger and a motorbike trickle charger putting out 0.6 amps. Would either of these be O.K? Quote Link to comment Share on other sites More sharing options...
kent Posted August 8, 2012 Report Share Posted August 8, 2012 I've been looking at two gazillion candle power lamps. Then you need the biggest darn battery you can carry, can't see much point to over powerfull lamps - your meant to see them and shoot em not burn thier little eyes out. Seriously too much power is counterproductive more often than productive IMO Quote Link to comment Share on other sites More sharing options...

Would either of these be O.K? The 0.6 amp would be fine. Any 10, 12 or 14Ah battery will serve you well even if you run a 100 watt (eg Lightforce 170) bulb.

wymberley Posted August 8, 2012 Report Share Posted August 8, 2012 (edited) Which charger would you suggest.I would like one that gives an indication of when the battery is fully charged. For the larger Ah units, Deben do a 0.5 A indicator version. Edited August 8, 2012 by wymberley Quote Link to comment Share on other sites More sharing options...
houlsby Posted August 9, 2012 Report Share Posted August 9, 2012 Pah.. I love my job, unlimited supply of brand new fully charged 7ah batteries and charging systems. no messing about, 3 in a rucksack and jobs a good en! (part of my job is fitting battery monitoring systems on water works) Quote Link to comment Share on other sites More sharing options...
hillmouse Posted August 12, 2012 Report Share Posted August 12, 2012 (edited) Cheap option is the 7Ah taken from replacement programme for emergnecy lighting in commercial premises. Might last 3 years, might already be stuffed. As they are only £20 I would buy new and have a warranty. Car charger will cook them, heat them and if forgotten about split them. Dedicated trickle chargers are the way to go. The Lithium ions are absolutley fantastic, typically 25% of the weight, double the endurance and 5 times the price of SLA but worth every penny for convenience. The 22Ah will power a 2 gazzilllion lamp, weighs the same as a bag of sugar and will last long enough to see to phone the fire brigade to come and put out the stubble fire the 2 gazzilion lamp caused. Or with a sensible lamp do a whole night. Edited August 12, 2012 by hillmouse Quote Link to comment Share on other sites More sharing options...
