charger
A battery charger, or recharger, is a device that stores energy in a battery by running an electric current through it.
The charging protocol (how much voltage or current for how long, and what to do when charging is complete) depends on the size and type of the battery being charged. Some battery types have high tolerance for overcharging (i.e., continued charging after the battery has been fully charged) and can be recharged by connection to a constant voltage source or a constant current source, depending on battery type. Simple chargers of this type must be manually disconnected at the end of the charge cycle. Other battery types use a timer to cut off when charging should be complete. Other battery types cannot withstand over-charging, becoming damaged (reduced capacity, reduced lifetime), over heating or even exploding.
The charger may have temperature or voltage sensing circuits and a microprocessor controller to safely adjust the charging current and voltage, determine the state of charge, and cut off at the end of charge.
Chargers may elevate the output voltage proportionally with current to compensate for impedance in the wires.A trickle charger provides a relatively small amount of current, only enough to counteract self-discharge of a battery that is idle for a long time. Some battery types cannot tolerate trickle charging; attempts to do so may result in damage. Lithium-ion batteries cannot handle indefinite trickle charging.Slow battery chargers may take several hours to complete a charge. High-rate chargers may restore most capacity much faster, but high rate chargers can be more than some battery types can tolerate. Such batteries require active monitoring of the battery to protect it from overcharging. Electric vehicles ideally need high-rate chargers. For public access, installation of such chargers and the distribution support for them is an issue in the proposed adoption of electric cars.
The MJ3 Charger on my Mainsboost system has stopped working and I have sourced a replacement, but need a plumber that understands these installations to come and replace that unit and ensure it's commissioned properly. Let me know if you've worked with this system before and can quote on...
Hi does anyone know if the lochinvar eco charger system has a sell on value? I’ve recently taken 3 out of a hotel in London and was wondering if it was worth trying to forward them on.
Cheers
Hi,
We have <2 bar coming into the house, sometimes as low as 1bar and on occasion .8bar. Thames Water been out, won't / can't do a thing. Not obligated to do so since 1bar recorded delivered on average over a week (logger fitted).
We have a terrace house, loft extension has a power shower...
Hi, does anyone know what I could use temporarily to charge my anton charger. I have left the charger at a house I wont be able to get back to till Tuesday. Thanks for any help.
As in title, one battery very good, the other fairly good but wont hold as much charge as the first. Drill in very good condition. Overall good cosmetic condition and well looked after. Includes carry case and charger £100 ono
Makita BHR200 sds cordless drill 1x3.3 ah battery and charger
surplus to requirements havent used it for a while.
looking for around £90.00 inc postage.
My local Lidl stores are doing this tomorrow. Maybe same elsewhere. If you haven't got a similar charger, then buy this at only £13.99.

Just thought I'd offer this up on here first before putting it on eBay.
Got a Milwaukee 18v fuel impact driver for sale, with case, charger and 1 3.0ah battery. All have been used but are in great working condition.
Only selling because I have two but used to let my apprentice use it when...
makita 24v drill body and charger only, NO BATTERIES.
Ideal as a spare, or if you have an apprentice that keeps borrowing your drill. I had as a spare but as i'm no longer on the tools I have no use for it.
as it is all packed ready to go £45 posted.
Hi,
I will soon be installing a multi-fuel stove with back boiler (Woodwarm Fireview 9 with 8.82kw to water) in my living room, with the intention of heating my hot water indirectly and running some radiators. I have done some research on load valve systems and very much like the concept.
I...
