Does the coleman charger 1 spotlight model # 5347a718 need a battery

TR2.6-12 is the battery you need.

Hi Mary, go to batteryspec.com. In the search box put in TR2.6-12 even though it's 2.6, it equates to 2.8 for our spotlights. The battery is around $20 with a 1 year warranty, and has the same specs (dimensions, terminal position) as ours.

6 volts rechargeable battery. Check with the manufacture for a recharger for the 110v and or a car charger for your light.

If the voltage and tip polarity of your replacement charger matches the charging port on your spotlight, there's no reason why it shouldn't work as a substitute for your original charger. Note, however, that if your original charger was more powerful (say, 1.5 amps instead of the 1-amp charger you have here), it will take noticeably longer to fully charge your spotlight than the original charger took. it's not a problem if the original charger had a lower mA rating than the replacement in your hand--the spotlight will sip an appropriate amount of juice from the charger.

The short answer is "The tip should be set to positive (+).

I found an old Vector VEC127Y Spotlight. It appeared to be in perfect condition but the battery was dead and there was no charger. I was able to buy a replacement battery at BatteriesPlus for $21 USD. Here is the link for the battery

I also purchased a Universal A/C adapter to use as a charger at BatteriesPlus for $17 USD. Their site does not list it yet but here is the manufacturers link. Please note the original battery was rated 6Ah. The replacement is only rated for 5Ah. Which means one less Amp hour (Ah). Which means a shorter run time, after charging, than the original battery had. Otherwise they are equal.
UNIVERSAL AC ADAPTER
I installed the new battery. I set the AC Adapter to 6V and installed the largest of the seven adapter tips that came with the charger, with TIP set to be positive (+). I opened the battery compartment of the spotlight and disconnected both the red (positive +) and black (negative -) battery leads from the battery. I then plugged the adapter tip of the Universal AC Adapter into the spotlight and plugged the AC Adapter plug to a power outlet. With a multimeter I tested the polarity of the spotlight battery leads while charging. I was able to confirm that the Adapter TIP should be set to positive (+). After reconnecting the spotlight battery leads and setting the AC Adapter to charge, I have a perfectly great spotlight in full working order.

Unfortunately the batteries lose their ability to charge when not used for an extended period of time. The light is very simple to dismantle by removing the black rubber ring that holds the lens on and then removing the screws. I believe the following battery may be the replacement you need.

Depends upon the model, but most use 12v 500Ma batteries w/ a barrel-pin connector.
