If you have tried discharging the batteries prior to charging them already with no result and from what you describe in your post, then I would have to say the charger has issues. Go to HD or Lowes (not sure if Lowes carry Makita) but another charger and test your battery again. If you get the same fault, there is an issue other than the charger, if not you need a new charger anyway. If you get the same fault with the new charger, you can always return the new one. Short of opening up the charger and using a volt meter, this is the easiest way to test to pinpoint the real problem. I hope this helps and good luck!

Polaroid rechargeable batteries in duracell charger


The problem isn't the brand of batteries Vs. charger; the problem is the electrical rating of the charger Vs. the charging specifications for the batteries. First make sure that the batteries are the correct type; i.e., nicad, lithium ion, etc. Do not try to recharge alkaline batteries. Your batteries have a mili-amp hour rating either shown on the battery or in the manufacturers specifications that are available on line. Each battery type also has charging specifications. The battery charger is designed to provide a specified charging voltage and current to the batteries and those specifications must match the battery's design. Using the incorrect charging voltage and current can cause the batteries to overheat and even explode.

Check that you have the correct battery in the charger as the charger will not charge any type of battery, only the battery type listed on the panel.

Some manufacturers put some chip on their battery so it can be identified by their charger. If you use a generic battery often, it will not charge or work properly. LG does this with their phone batteries! So you have to use another charger to charge them.

Can my makita bl1830 battery be repaired if it does not hold charge anymore


This battery has a known design defect that causes premature failure. The battery is still probably good, but the safety circuit n the battery spuriously locks it, due to a bug. Once locked, it won't charge in the Makita charger (flashing red and green lights). Makita knows about this problem but so far is not actively recalling the batteries. Makita will replace the pack if the charge count is under 150 (some people say 300?) regardless of warranty status, but you have to take or mail it to a Makita Service Center -- the dealers won't handle this unless it's in warranty.

If Makita won't fix it, you can try to repair it. If the red and green lights are flashing, the battery is probably locked and cannot be repaired in a way that will let it be charged in the Makita charger (but it can be charged in off brand chargers). Buy a clone charger on eBay for $60 and try it. If it charges, just use it, no repair needed.

Be aware that lithium batteries do lose capacity permanently at a rate of about 20% per year. So, 3-6 years is about the best battery life you can expect - from date of manufacture, so if it sat in the store a while that adds. Makita derates the cells to allow for some shelf life (down from 2400 Mah to 1500 Mah rating).

If the battery is weak, and only gives brief usage, you can replace some of or all of the cells in the battery. These are expensive and worth repairing. See this video:
http://www.youtube.com/watch?v=Z5taguEdlkY

If just 1 or 2 cells are weak, you can replace them with the same Sony 18650 size 2400 Mah capacity battery, green sleeve. The Sony's are not sold retail, and are hard to find other than from another Makita pack or from some laptop packs. If more are weak, you're better off just replacing all of them with new 18650 2400 Mah (or higher) batteries with tabs. Look for Tenergy or other quality brand.

Hope that helps.

I bought a new highter current ni cad for my makita; however, the


As long as the charger voltage and the battery voltage match (7 volts) there should be no problem. A fast charger just runs more current thru the battery (per unit time) than a not-so-fast charger. If you notice the battery getting really hot when it's charging (like too hot to touch), stop using it.

I think your tryiong to charge NIMH batteries oon a charger designed for Lithium Ion batteries. With all the new style batteries such as NICAD, NIMH and LI-ION, charging becomes difficult. Most chargers pre NIMH and LI-ion, were designed for NICAD's. The best advise, match your batteries with the correct charger
