Product Information

Battery Storage - If you don't plan on using the Power Tool battery for a long time, store it in a clean, dry, cool place away from heat and metal objects.

As battery technology has advanced, so recharging times have reduced. Old NiCad batteries always seemed to take hours (and many did). Modern Li-ions recharge much more rapidly. Don’t store drained batteries. If you’re storing batteries for any length of time, don’t leave them with no charge because they may not “wake up” when you want to charge them again. Experts recommend charging to about 50%. Makita’s LXT batteries, for example, are supplied with 30% charge, which is “for storage purposes only.” A. Makita warns that non-genuine batteries could perform poorly, catch fire, damage the charger, and so on. Their use will certainly void the tool warranty. Any of these things might be true, but let’s not forget that Makita has a vested interested in selling you its own battery! time and has not been scientifically proven to work, so in most cases, your best bet is to replace the old battery.You could try opening the casing and looking for some obvious disconnection fault, but if the electronic control circuit is faulty you will need an electronics specialist to repair it.

Use the full capacity of the battery between charging for best results. Simply put, as a rule of thumb, you should discharge completely and charge completely.This battery has been manufactured with high quality components. It conforms with the exact specification of the original manufacturer and the battery is guaranteed against all manufacturing defects. Don’t overcharge the batteries. Overcharging can dramatically reduce the performance of your batteries, particularly NiCd and NiMH types. A short while won’t make much difference, but don’t leave batteries in the charger for any longer than necessary after they’ve reached full charge. Some Makita batteries have circuitry to prevent overcharging, but it’s best not put it to the test. Makita’s Lithium-ion Extreme Technology (LXT) batteries have useful charge indicators. We have 10-year experience on batteries. As a professional manufacturer of power tool batteries, Waitley focuses on the stability, safety and compatibility of replacement batteries.

Don't store a discharged battery that has less than one-half charge. Give it a full charge and then store it. Be prepared for any unpleasant chemical spillage - ventilation/gloves/goggles/bath sink - I've no idea what is in these batteries! Exercise the Battery - Do not leave the battery dormant for long periods of time. We recommend using the battery at least once every two to three weeks.PA18|1850|253023|1820|192827-3|1928273|1928281|1928299|193060-0|1930600|1930618|1931020|1931402|1931591|1937830|193784-8|1937848|194105-7|1941057|194107-3|1941073|194158-6|1941586 Our warranty does not extended to any products that are physically damaged or that are not under normal operating conditions as a result of misuse or improper installation on the buyer/user's part.
